2.1 DESCRIPTION OF GRANULATOR

This family of granulators has been designed for effective granulation of plastic and rubber of various sizes. The granulator consists of a loading hopper (in which material for grinding is placed) connected to a cutting chamber where a series of rotating and fixed blades reduce it to granules, the size of which is determined by the holes in the grille. These granules drop down to the collection box.

NOTE If required, the collection box can be replaced with a “granule extraction cone”

controlled by a powerful suction system or (alternatively) by a screw-type mechanic conveyor system that outlets them.

It has also equipped them with all the safety devices and protection deemed necessary. Finally it has provided them with sufficient information for safe, correct use. In accordance with the ‘Workplace Lighting’ requirements, the premises accommodating the granulator shall have no areas of shade, tiresome dazzle or hazardous stroboscope effects due to the lighting at the workplace. Ideal ventilation of the premises shall also be guaranteed, with appropriate use of proper extraction plant if provided. The granulator shall be used only by QUALIFIED OPERATORS and is built to granulate PLASTICS. Materials other than those stated may only be used by written permission of PLASTIC SYSTEMS S.p.A.. Lack of such permission shall exonerate the manufacturer from any liability whatsoever for possible damage to the granulator, objects, persons and animals. Operating, maintenance, cleaning and inspecting staff etc. shall act in strict compliance with the accident prevention standards of the country of destination of the granulator. The operator is advised to wear suitable clothing for the respective working environment and situation. The person assigned to the granulator or its maintenance is asked to pay careful attention to the clothing worn, e.g.: - Avoid wearing clothes with parts which may become trapped in parts of the granulator; - Avoid wearing scarves or other loose items of clothing; - Avoid wearing cumbersome rings or bracelets which may trap hands in parts of the granulator. Before starting work the operator shall be fully aware of the positions and functioning of all controls and features of the granulator.

NOTE SEE SECTION 0.4 FOR EXACT OPERATOR QUALIFICATIONS Paragraph 1.5 ‘Glossary’ defines various terms used in this paragraph. Ordinary and extraordinary maintenance and cleaning shall take place with the granulator at a standstill and disconnected from the electricity supply. When making the electric connections, it is sound practice to comply with the general rules of installation and connection; these operations shall be carried out by qualified staff. Do not modify parts of the granulator for any reason. In case of malfunction due to breach of this requirement, PLASTIC SYSTEMS S.p.A. will not be answerable for the consequences. We advise making written requests for any modifications direct to the manufacturer.


3 - 3

Clean the granulator coverings, panels and controls with soft cloths, either dry or dipped in a mild detergent solution. Do not use any solvent such as alcohol or benzene which might damage the surfaces.

N.B. Qualified staff are defined as those who have followed specialisation and training courses etc. and who have experience of granulator installation, start-up and maintenance.

3.2 INTENDED USE, UNINTENDED USE AND IMPROPER USE

3.2.1 Intended use

The machine described in this manual is designed for the granulation of the plastic and rubber materials stated in the terms of the contract and within the prescribed limits. 3.2.2 Unintended use

The use of the granulator for processing materials that are not specified in the terms of the contact, or to obtain results that are outside the prescribed capabilities of the machine, are construed as "UNINTENDED USE" and therefore constitute "IMPROPER" use of the machine.

ATTENTION The machine must not be used to process flammable, explosive, toxic/noxious,

ferrous materials or materials that develop any of the foregoing characteristics when subjected to processing.

The machine is not designed for use in explosive atmospheres and it must not therefore be installed in places subject to the presence of explosive atmospheres.

PLASTIC SYSTEMS S.p.A. declines all liability for damage that may be caused to property or injury to persons resulting from improper use of the machine, and in such circumstances shall also consider the warranty to be completely invalidated.


3 - 5

3.3 SAFETY DEVICES

Granulators are provided with safety devices to protect workers and the granulator itself. The user is therefore warned not to remove or tamper with such devices. 3.4 SAFETY DEVICES INSTALLED ON GRANULATOR

All moving parts are enclosed by protective cases which cannot be removed without specific equipment and, moreover, cannot remain in their proper positions without fastening attachments.

ATTENTION Always make sure the casing is fitted before starting the granulator. Fig. 3-1A Emergency Stop Buttons Both the front side of the machine and the control panel are provided with EMERGENCY STOP BUTTONS (a red mushroom-head push-button on a yellow background) Ref. ‘A’ - Fig. 3-1A and 3-1B. This button must be used whenever an emergency situation arises. When pressed, it triggers an immediate halt of all moving components.

N.B. Pull red button outwards to release.


3 - 6

Fig. 3-1B The machine only resets after "RESET" button is pressed. The top of the cutting chamber is protected by the hopper which feeds material for grinding, while the bottom is enclosed in the machine structure.

Fig. 3-2 Front panel opening electromagnetic safety switch The cutting chamber is accessible by opening the front panel, the catch of which is controlled by an electromagnetic safety switch Ref ‘D’ - Fig. 3-2. When released, this triggers a halt of the machine. About 30 seconds after rotor has come to a complete halt, the rotation sensor sends a pulse to the ELECTROMAGNETIC SWITCH which releases the front door; at this point the front panel can be opened unscrewing completely the knob Ref. "C" - Fig. 3-2.

ATTENTION The electromagnetic safety switch releases and opens the front panel only if the

granulator has already been connected to the supply mains and the MAIN SWITCH, Ref. “E” Fig. 3-1B, is in Pos. "ON".

IMPORTANT Before releasing the front opening, check that the emergency push-buttons are

disabled. To reset, close the front panel, screw up the knob, then press Reset button.


3 - 7

Rear panel opening safety microswitch Fig. 3-3A The safety microswitch on the rear panel is controlled by a plate, Ref. "E" - Fig. 3-3A, which is integral with the panel. When the panel is closed, the plate presses against a screw, Ref. "F" - Fig. 3-3A, that activates the microswitch; opening the panel serves to deactivate safety microswitch "G" - Fig. 3-3B, which disconnects the power supply to the motor causing the rotor to stop. To reset, close the panel so that the plate operates the safety microswitch and then press the Reset button. Fig. 3-3B

3.5 SOUND CHARACTERISTICS OF GRANULATOR: NOISE LEVEL GENERATED

Noise tests were performed by the ENGINEERING OFFICE OF VALERIO TARABUSI, ASSOCIATED PROFESSOR OF ENGINEERING PHYSICS AT THE FACULTY OF ENGINEERING, BOLOGNA. 3.5.1 Series G40 granulator noise test

Research has been conducted to assess the noise generated by the operation of Granulators Models G40-50, G40-70, G40-90 standard version and suction fan version, manufactured by PLASTIC SYSTEMS S.p.A.. - Borgoricco (Padova). 3.5.2 Noise levels generated: background regulations and Test methods

Reference was made to the following technical regulations to establish the noise emitted by the machine: S.P.I. NOISE TEST - Noise Measurement Procedure for Granulators, by Society of the Plastic Industry. UNI 7712 - Machine Tools - Determining Noise in the Working Environment - 1977 ISO 3746 - Acoustics - Determination of sound power level of noise sources - Engineering method for free field conditions over a reflecting plane - 1981. ISO 3746 - Acoustics - Determination of sound power level of noise sources - Survey method - 1979. DIN 45635 - Measurements of airborne noise emitted by machines - Enveloping measuring method - 1972. The technical specifications of the granulator PLASTIC SYSTEMS S.p.A.Mod.

3.9 RESIDUAL RISKS AND HAZARDS

3.9.1 Residual cutting hazard

When handling the blades (maintenance, adjustment, replacement), the sharp edges constitute a cutting hazard.

WARNING The operator must adopt appropriate personal protective equipment, namely cut-

resistant gloves according to the requirements indicated in standard EN 388; the operator must also protect the blade cutting edges with rubber guards.

3.9.2 Residual risk due to noise

Even though the measured sound pressure levels are within the established safety limits, prolonged exposure to the noise of the machine can cause damage to the hearing of operators or other exposed persons. It is therefore recommended to install the machine in a soundproof enclosure, or to equip all exposed persons with relative personal protective equipment such as hearing protectors, safety earmuffs or earplugs.

Important! The clothing worn and the protection devices used must comply with the EEC

Directive 686 concerning personal protective equipment, or alternatively, with statutory regulations in the country of installation of the machine.

3.9.3 Residual risk caused by jamming of the rotor

In the event of rotor jamming caused by a build up of material in the cutting chamber, the operator's action carried out in an attempt to remove the jam could lead to a potentially hazardous situation.

WARNING Do not act impulsively or without thinking. The operator must adhere strictly to the rotor clearing procedure described in

heading 7.10 of this manual.

4.1 RULES FOR MOVING THE MACHINE

To lift and move correctly and safely: - Use the equipment with the most suitable features and capacity; - Cover sharp edges. Before proceeding to lift: - Check that there is no material which may fall during the lifting stage. Before positioning the granulator, check that: - The floor is level and strong enough to bear the load; - There is sufficient room in the installation area for movement of products for processing

without obstructing necessary maintenance operations. 4.2 TRANSPORT AND INSTALLATION

The granulator is normally dispatched without packing, protected by a cellophane wrapping and installed on pallet. It is advisable to check for any damaged caused during transport on receipt and immediately notify it to the carrier. Also check that the list of components supplied on the delivery note matches the content of the packing. Together with the granulator, the customer will receive the instruction manual as well.

ATTENTION Before lifting or moving the granulator, check the weight marking on plate attached to

the granulator (see par. 3-6).


4 - 3

4.3 LIFTING

The granulator can be lifted with a forklift truck. Fig. 4-1

WARNING Before lifting the granulator, check to

ensure that the lift truck capacity is adequate in relation to the weight of the load.

When lifting the machine, observe the following procedure: • Secure to the base holes (Ref. "A" - Fig. 4-1),

by means of 4 M16 bolts, the lifting bar (Ref. "B" - Fig. 4-2), supplied with the machine, equipped with channels through which the forks can be inserted.

• Insert the lift truck forks into the lifting bar channels (Ref. "C" - Fig. 4-2) and then lift the machine.

• After having positioned the machine body as desired, remove the lifting bar. Fig. 4-2

ATTENTION During movement, the load must remain

in a horizontal position, regardless of the type of equipment used.


4 - 4

4.4 INSTALLATION

IMPORTANT Make sure the base on which the granulator rests is compact, even and perfectly flat

so that it holds the granulator rigidly without the slightest oscillation. The recommended flooring is reinforced concrete with a very smooth support surface.

POSITION GRANULATOR IN A SUFFICIENTLY ROOMY AREA TO LEAVE THE NECESSARY SPACE ON ALL SIDES FOR THE OPERATOR TO CARRY OUT ALL MAINTENANCE OPERATIONS. This granulator is designed to run without water. Although the fitted electric components are designed to EEC regulations, they must operate without moisture or water. We therefore advise installing the granulator in an environment sheltered from the weather and isolated from any water there may be on the ground. Having positioned granulator, disconnect eye-bolts from hooks and close panels in reverse order to opening. Detach control panel from harness used for transport and position alongside the granulator.


4 - 5

4.4.1 Levelling

Fig. 4-3 The granulator rests on 4 adjustable feet (Ref. ‘A’ - Fig. 4-3) which are used for levelling as follows: • Loosen locking upper and lower nuts "B" -

Fig. 4-4 on each machine foot. • Perform the adjustment on the right and left

sides, causing each foot to slide upwards or downwards as necessary.

• For adjustment of the rear feet lift the machine with a fork lift truck in order to gain access to the locking nuts.

• Tighten locking nuts "B" - Fig. 4-4. • Ensure that the feet are all resting on the

floor.

Fig. 4-4

4.5 ELECTRIC CONNECTION

N.B. Have this work done by a qualified ‘operator/electrical maintenance technician’. To start the granulator, ensure that the electric power cable is well made and reliable, protected by an automatic line switch and connected to a good earthing system to prevent the machine becoming a dangerous source of electric potential.

ATTENTION Before carrying out this operation, make sure line voltage is as stated on granulator

plate and that master switch (Ref. ‘E’ - Fig. 3-1B) is in the ‘OFF’ position. UNLESS OTHER VOLTAGES ARE REQUESTED AT THE TIME OF ORDERING, THE GRANULATOR WILL ALWAYS BE SUPPLIED FOR 400V 50 Hz.

IMPORTANT Choose a suitable electric cable for the power of the motor installed, bearing in mind

that it may be working 24 hours a day.

5.2 PRELIMINARY CHECKS BEFORE START-UP

N.B. The following procedures must be carried out by a qualified operator / maintenance

mechanic. 5.2.1 Checking the cutting chamber

IMPORTANT Before starting the granulator open the cutting chamber and check that no foreign

material has entered during the machine transport or installation operations.

ATTENTION It is important for the operator to wear work gloves thick enough to prevent his hands

being injured by touching sharp parts or blade cutting edges during this operation. The operations to carry out are as follows: 1) Set the main switch to the "ON" position to activate the electromagnetic safety switch that

locks front panel opening. 2) Wait for the safety switch to unlock the panel (approx. 30 seconds) and then fully unscrew

knob "C" - Fig. 3-2 and open the front panel. Fig. 5-2 3) Lift the front mobile guard (Ref. 1 - Fig. 5-2)

and secure it to the hopper by the expansion catch on the guard in order to gain access to the hopper fixing screws.

4) Unscrew the four screws (Ref. A - Fig. 5-2)

responsible for securing the hopper to the cutting chamber.

5) Return the main switch to "OFF" and then

disconnect power from the granulator and remove the fuses from the main power panel.


5 - 4

Fig. 5-3 6) Tip the hopper fully back to achieve

unrestricted access to the cutting chamber and then check for the possible presence of foreign objects.

7) When the hopper is tipped backwards the

rear closing panel (Ref. B - Fig. 5-3) opens by sliding towards the rear.

Fig. 5-4

IMPORTANT If you wish to access the

motor/transmission compartment at this point, lift the rear panel and secure it to the rear wall of the hopper by means of the expansion catch on the panel (Ref. C - Fig. 5-4), then return the hopper to its starting position.

After performing the check, close the hopper (unless it is secured to the hopper also the rear panel will close automatically), then close the front mobile guard and finally, the front panel.


5 - 5

Fig. 5-5

NOTE If the mobile front guard does not close it

will not be possible to close the front panel. This is because when the mobile front guard lowers it also depresses the safety plate, which otherwise prevents the front guard from closing, see Fig. 5-5.

After having re-closed all the parts the fuses can be reinstalled in the main panel.


5 - 6

5.2.2 Check of granulator rotation direction

Check correct direction of rotation ofimpeller as follows: - Turn master switch to position ‘ON’. - Press start button, holding it down for about one second, so that start clearances are checked

and granulator can start. - Check through the drive-guard spyhole that the rotor rotation direction is as stated on the plate

with a straight arrow attached above the protective guard. If direction of rotation is correct, granulator is ready for use.

ATTENTION If impeller is found rotating in the opposite direction to the straight arrow on plate, to

correct the direction of rotation, stop granulator by pressing EMERGENCY STOP; then cut off current by turning MASTER SWITCH to position ‘OFF’, disconnect fuses from line supply panel, then reverse one of the three electricity supply phase conductors inside the control panel.

After these operations, close control console door, refit fuses to power line supply panel, turn MASTER SWITCH to position ‘ON’ and reset EMERGENCY STOP button by pulling the red mushroom-head outwards. Press START button and hold down for about one second, then recheck that direction of rotation of rotor is correct. 5.2.3 Checking the direction of rotation of the suction fan (if installed)

Fig. 5-6 Start the suction system by pressing the "SUCTION FAN START" button. Check, through the inspection window that the direction of rotation of the motor corresponds to the direction indicated by the dataplate with the straight arrow (Ref. D - Fig. 5-6); if the motor is running in the wrong direction, invert the positions of two of the power feeding phase wires.


5 - 7

5.2.4 Checking position of fixed blades

ATTENTION It is necessary for this operation to be performed by a qualified ‘operator/mechanical

maintenance technician’ wearing protective gloves. Before starting any kind of working it is IMPORTANT to check the distance between fixed and rotating blades using the thickness gauges provided. Fig. 5-7

WARNING To gain access to cutting chamber,

follow the same procedure and take the same precautions as in heading 5.2.1; moreover, before performing the check it is advisable to lock the rotor to prevent it from rotating independently.

N.B. Please note that the distance left by the

manufacturer for normal applications is 0.15 - 0.20 mm.

Use a thickness gauge Ref. “A” - Fig. 5-7 to check the distance between the fixed and rotating blades. If the space between the fixed and the rotating knives is found to be significantly more than 0.15 - 0.20 mm, it will be necessary to adjust it (see specific section on Knife Adjustment). After performing the check re-close the hopper and all the panels.


5 - 8

5.2.5 Checking position of rotating blades

Fig. 5-8

ATTENTION It is necessary for this operation to be

performed by a qualified “operator/mechanical maintenance technician” wearing protective gloves.

WARNING To gain access to the cutting

chamber, follow the same procedure and take the same precautions as indicated in heading 5.2.1; moreover, before performing the check it is advisable to lock the rotor to prevent it from rotating independently.

Using an 0.05 feeler gauge (Ref. "A" - Fig. 5-8) check correct positioning of rotating knife, Ref."B" - Fig. 5-8. If the knife is not correctly positioned loosen the fixing screws (Ref."C" - Fig. 5-9), reposition it and then lock it by means of a torque wrench. Fig. 5-9

NOTE Driving torque of rotating blade bolts:

20.2 Kgm. (202 Nm.).

IMPORTANT Smear a light coat of lube oil on all

screws to prevent seizure. After performing the check re-close the hopper and all the panels.


5 - 9

5.3 OPERATING MODES

Granulator is designed to operate exclusively in automatic mode. After having enabled all the units required for the production cycle, the granulator requires exclusively the supply of material, which can be performed manually by the operator, or automatically by means of a feeding system.


5 - 10

5.4 STOP AND EMERGENCY MODES

5.4.1 Stopping the work cycle

To stop the work cycle proceed as follows: - Ensure that the cutting chamber is empty;

ATTENTION Before pressing the "GRANULATOR STOP" pushbutton, ensure that the cutting

chamber is completely empty; to make this check it is sufficient to listen to the noise made by the granulator; when the granulator starts to run silently, you can assume that the cutting chamber is empty.

- Press the "GRANULATOR STOP" button; - Press the "SUCTION UNIT STOP" pushbutton, if the suction option is installed.

5.4.2 Emergency stop

The emergency stop, performed by pressing the mushroom head emergency pushbutton, causes the machine to stop immediately and disconnects the power supply. This type of stop must be carried out to stop the machine in case of hazard to persons and things, or in case of a long idle period of the machine and before performing maintenance work.

ATTENTION This type of stop shall only be used when emergency conditions really occur.

NOTE To reset the emergency pushbutton pull the mushroom head outwards. 5.4.3 Stop due to electrical power loss

In the event of an electrical power failure, the operating cycle will stop immediately; this situation could result in jamming of the rotor because of the material still present in the cutting chamber. To restore normal operating conditions following a power loss, perform all the checks already described in headings 5.2.1, 5.2.2, 5.2.3, 5.2.4 and 5.2.5 and, if necessary, perform the "ROTOR UNBLOCKING" procedure as described in heading 7.9. For any adjustments that may be required, refer to chapter 7 "MAINTENANCE".

6.1 OPERATIONS FOR START-UP AND PRODUCTION

ATTENTION Before starting the granulator, always check for and remove any equipment, tools or

other objects placed on the granulator. Turn MASTER SWITCH to position ‘ON’, then press START button and release only when motor has started. Fig. 6-1

NOTE The electrical system of series N40

granulators is supplied prearranged for inclusion of a granulate conveyor system with suction unit (OPTIONAL). Therefore, before starting the granulator press the SUCTION UNIT START button, irrespective of whether this optional unit is present or not. Likewise, after the granulator has been stopped, press the SUCTION UNIT STOP button.

N.B. These granulator models are supplied

with ‘star delta’ electric system as standard. This means the motor starts at 660 V (to reduce current consumption at time of starting). Then, after approx. 10 - 15 seconds, it switches automatically to 400V.

It is perfectly normal for the motor to delay starting, as the electronic system has to check all the clearances at the various microswitches before clearing it to start. WAIT FOR ELECTRIC MOTOR TO REACH NORMAL SPEED OF ROTATION BEFORE FEEDING MATERIAL INTO THE GRANULATOR.

ATTENTION Avoid pressing material into hopper with the hands in any way when granulator is

running.

6 - OPERATION N40/Rev. 00.02.08 EN

6 - 3

If the hopper clogs, stop the granulator, turn off power supply and remove fuses.

IMPORTANT If the granulator stops repeatedly while working, it is necessary to check the setting

of the THERMOSWITCH ‘D’ - Fig. 6-1 (see figure shown on circuit diagram). Before stopping the granulator at the end of a shift or for other reasons, stop the supply of material for granulation and wait a few minutes to allow the cutting chamber to finish grinding the material inside it. Then press stop button.

ATTENTION Before pressing the stop button, make sure the cutting chamber is completely empty.

To check this just listen to the noise coming from the granulator. When it becomes silent, it means the cutting chamber is empty.

NOTE Should the granulator lock or stop with the cutting chamber full of material, proceed

emptying the room by removing the granules collection box and lowering the grid holder along with the grid.

NOTE It is good practice to clean the machine carefully after each work shift.

IMPORTANT When cleaning operations are concluded always check for possible residues of

granulate in the motor/transmission area and remove any residues fine by means of a vacuum cleaner.

7.1 GENERAL PRESCRIPTIONS

Before doing anything, read the instructions in this publication carefully.

ATTENTION Rely on specialised and skilled staff for these operations (see heading 0.4). - All maintenance operations shall be carried out with the granulator stationary and

disconnected from the electricity mains. - When the electric equipment is live, some parts of it may be dangerous. - Failure to follow the safety instructions when using such equipment may cause personal injury

or damage to objects. - Strictly follow the instructions in the paragraphs concerning each maintenance operation. Having carried out the maintenance work, before returning the granulator to service check that: 1 Any parts replaced and/or equipment used for the maintenance have been removed from the

granulator. 2 All safety devices are working.

IMPORTANT After the first week of production, check the tensioning of the drive belts. The correct

working tensioning level shall be the minimum required so that the belts do not slip. Check that the pulleys are properly aligned one with the other, as well.

IMPORTANT If it becomes necessary to wash the granulator never use pressurised water jets.


7 - 3

7.2 CHECKING THE SAFETY DEVICES

IMPORTANT At the start of each working shift, perform the checks listed below.

IMPORTANT If safety devices must be repaired or replaced, rely on skilled and competent

personnel (see heading 0.4), or on CMG technical service department. 7.2.1 Checking the emergency stop pushbuttons

With the machine empty and set up for operation, perform the following operations: 1) press the "SUCTION UNIT START" pushbutton, and hold it down for about one second to

allow the transmission of all the relative enable signals so that the suction unit (if present) can start;

2) press the "GRANULATOR START" pushbutton, and hold it down for about one second to allow the transmission of all the relative enable signals so that the granulator can start;

3) now press one of the emergency stop pushbuttons, and check that both the granulator and the suction system (if present) are stopped;

4) when you have finished performing the check reset the emergency pushbutton that was pressed by pulling the mushroom head outwards.

IMPORTANT Peform the foregoing check for each of the emergency pushbuttons.


7 - 4

7.2.2 Checking the front panel opening safety electromagnetic switch

With the machine empty and set up for operation, perform the following operations: 1) press the "SUCTION UNIT START" pushbutton, and hold it down for about one second to

allow the transmission of all the relative enable signals so that the suction unit (if present) can start;

2) press the "GRANULATOR START" pushbutton, and hold it down for about one second to allow the transmission of all the relative enable signals so that the granulator can start;

3) allow the machine to run for a few seconds and then press the following pushbuttons in

sequence: - "GRANULATOR STOP"; - "SUCTION UNIT STOP"; 4) if the sensor is working correctly, it doesn't allow opening the front door immediately. This is

because the microswitch connected to sensor allows opening the front door only when the sensor detects no rotor movement (30 sec. about).

7.2.3 Checking the rear panel opening safety microswitch

With the machine empty and set up for operation, perform the following operations: 1) execute all the operations described in heading 5.2.1 up to point 7; 2) raise the rear panel and secure it to the hopper by means of the expansion catch, see Fig. 5-4; 3) close the hopper, the front guard, and finally close the front panel, screwing down the knob

completely (Ref. C - Fig. 3-2); 4) Press the "SUCTION UNIT START" pushbutton and hold it down for approximately 1 second

and then press the "GRANULATOR START" pushbutton and check that the suction unit (if present) and the granulator do not start.

7.3 MONTHLY MAINTENANCE OPERATIONS

NOTE Have these operations carried out by an 'operator/mechanical maintenance

technician'. 7.3.1 Drive belt tensioning

Fig. 7-1 To achieve correct functioning of the granulator, it is of maximum important for the drive belts to be tensioned at all times. Correct tension reduces impeller bearing wear and minimises wear and stretching of the belts themselves. To check and tension if necessary, proceed as follows: 1 Execute all the operations described in

heading 5.2.1 up to point 7; 2 Raise the rear guard and secure it to the rear

wall of the hopper by means of the expansion catch, see Fig. 5-4; 3 Loosen the nut (Ref. A - Fig. 7-1); 4 Adjust the two tension rods (Ref. B - Fig. 7-1), tightening them sufficiently to achieve the

required tension. 5 Tighten the locking nuts of the two tension rods Ref. C - Fig. 7-1.

IMPORTANT Tighten the two tension rods (Ref. "B" - Fig. 7-1) by an identical amount such as to

keep the motor support axis perfectly perpendicular with respect to the belts axis. If all belts are equally tensioned when checked individually, this means the motor

support axis is positioned correctly in relation to the belts axis. When the adjustment has been completed free the rear guard and re-close the hopper.


7 - 6

7.3.2 Drive belt checking and adjustment

Check the tension of the drive belts initially after 8 or 10 hours of duty and, if necessary, adjust in accordance with the tabulated values. Check the tension and condition of the belts once a month thereafter. Whenever you adjust belt tension, recheck the situation after 20 or 30 duty hours at full load.

NOTE After tensioning the belts always check that the pulleys are correctly aligned.

IMPORTANT The following table contains the prescribed belt tensioning values.

which are located at their high position (Ref "A" - Fig. 7-11) with an adequate protection because the knives could present a hazard for the operator, who may suffer cuts since he is working above the knives.

3 Completely unscrew the screws Ref. C - Fig. 7-16 and remove the knife protection Ref. D - Fig.

7-16 and the fixed rear knife.


7 - 16

ATTENTION Before refitting blades, clean holder carefully with a rag.

N.B. To refit sharpened fixed blades, the same screws and washers that were holding it on

can be used. When new fixed blades are being fitted, however, it is necessary to replace the screws

and washers with new ones of the same strength.

NOTE Tightening torque for fixed blade bolts: Mod. N40-50 = 20,2 kgm (202 Nm). Mod. N40-70/N40-90 = 30,2 kgm (302 Nm).

IMPORTANT All screws must be moistened with a film of lubricating oil to prevent jamming.

Carefully clean holder of fixed blades before refitting them. Restore the correct distance with the rotating knives as already described in paragraph 7.4, then lock the screws with a torque wrench. Remove the protections previously fitted to cover the cutting edges of the rotating knives and then rotate the rotor slightly, checking through one complete revolution, the exact distance between the rotating knives and the fixed knives. Return the filling hopper to its lowered position and close the front panel, re-tightening the fixing knob. Re-install the fuses in the line supply panel and restart the granulator by setting the MAIN SWITCH to "ON" and pressing the start button.


7 - 17

7.7 REMOVAL AND REPLACEMENT OF ROTATING BLADES

N.B. Have the operation carried out by a qualified ‘operator/mechanical maintenance

technician’.



Fig. 7-17 If it proves necessary to sharpen or replace the rotating blades, it will be necessary to dismantle them, proceeding as described up to paragraph 7.3 point 4, then completely unscrew fastening bolts Ref. ‘1’ - Fig. 7-17 and remove blades.

IMPORTANT When rotating blades are removed for

sharpening, it is necessary to sharpen the complete set of blades.

ATTENTION Before refitting blades, clean holders carefully with a rag.

N.B. To refit rotating blades which have been sharpened only, the same screws and

washers that were holding them on can be used. When new rotating blades blades are being fitted, however, it is necessary to replace

the screws and washers with new ones of the same strength. Using an 0.05 feeler gauge (Ref. "A" - Fig. 5-8) check correct positioning of rotating knife "B" - Fig. 5-8. If the knife is not correctly positioned, loosen the fixing screws ("1" - Fig. 7-17), reposition it and then lock it using a torque wrench.

NOTE Tightening torque of rotating blade bolts: 20,2 kgm (202 Nm)


7 - 18

Restore the correct distance between the fixed knives and the rotating knives as already described in paragraph 7.4, then lock the screws with a torque wrench. Rotate the rotor slowly, checking the exact distance between the rotating knives and the fixed knives over one complete revolution. Return the loading hopper to its lowered position and close the front panel, re-tightening the fixing knob. Re-install the fuses in the line supply panel and restart the granulator by setting the MAIN SWITCH to "ON" and pressing the start button.

7.9 ROTATING BLADE SHARPENING SPECIFICATIONS

Fig. 7-19 A Min.length: 78 mm B New blade: 82 mm C grind these surfaces only Rotating blades must be sharpened to a tolerance of within 0.05 mm throughout their length. Greater variations cause difficulties in adjustment and lead to other serious faults in granulation.

IMPORTANT Minor scoring is acceptable following

regrinding of the knife. Never fit blades of smaller dimensions than those stated, because the blade

fastenings could foul the cutting circle of the blades. The impeller could also be impeded from rotation with serious damage to the blade supports and counterblades.


7 - 21

7.10 ROTOR UNBLOCKING PROCEDURE

NOTE Before performing any type of maintenance of the cutting chamber it is compulsory

for the operator to use suitable personal protection devices, i.e. work gloves having the characteristics specified by standard EN 388; also, the blades must be protected by fitting rubber guards to avoid injury to the hands through touching sharp parts or the cutting edges.

If the rotor becomes jammed because of a build-up of material in the cutting chamber, indicated also anomalous granulator running noise, proceed as follows: - press one of the emergency stop pushbuttons; - reset the emergency stop pushbutton; - leave the main switch set to "ON" so that the ELECTROMAGNETIC SAFETY SWITCH can be

activated and the front door is unlocked; - open the granulator; - padlock the main power switch. - empty the cutting chamber of all feedstock.

ATTENTION When the rotor is jammed, never try to free it with your hands: this operation is

extremely dangerous. Do not try to unblock the machine by placing your hands on the rotor, on the blades, or inside the cutting chamber. Keep hands well clear off the rotary trajectory of the rotor.

ATTENTION Before performing the following operations ensure that your feet are firmly planted on

the floor, that the floor is clean and unobstructed, and that your body is well balanced.

Beware of the possibility of losing your balance if the rotor should suddenly become unjammed.

To free the rotor when jammed by accumulated material, use a sturdy wooden lever of sufficient length to keep the hands well clear of the trajectory of the blades, and then lever the rotor in the direction opposite to the direction of rotation of the granulator. Use suitably long tongs to remove the material that caused the rotor to jam in the first place.

ATTENTION Be aware that the rotor may start to spin dangerously as soon as the obstructing

material is removed. After unblocking the machine, to restore normal operating conditions perform all the checks already described in headings 5.2.1, 5.2.2, 5.2.3, 5.2.4 and 5.2.5. For repair work (if necessary) refer to the procedures described in this section of the manual.

8.1 FAULTS, CAUSES AND REMEDIES

The following pages list certain faults which may occur with the granulator. These general indications allow any fault to be located and a quick repair to be made. In any case, when looking for causes of faults, it is sound practice to start with simpler checks before carrying out complicated dismantling and useless solutions.

Fault Possible Cause Possible Remedy Bearings overheating Blades moving in holders

Excessive belt tension There may be foreign material under the blade. Loose blade screws Weakened blade screws

Adjust belt tensioning Clean holder carefully. Tighten screws with a torque wrench. Screws must not be used more than six times.

9.1 DECOMISSIONING

When it has been decided no longer to use the granulator, it is recommended to disable it by disconnecting the supply cable from the mains and inserting any safety devices. 9.1.1 Scrapping the granulator

ATTENTION The granulator shall be scrapped by skilled personnel: both electricians and

mechanics. Before dismantling the machine, prepare an wide and orderly space all around it in

such a way as to allow personnel to move without obstructions, i.e. without creating risks for operators and exposed persons.

Proceed as follows: - Disconnect the machine from the electrical mains and the water supply (if present); - Detach all the wires at the output of the line disconnect switch; - Detach the electrical cabinet power feeding wires; - Close the cock controlling the water supply to the cooling circuit (if present), and detach the

water inlet and outlet unions from the machine;

ATTENTION If the above procedures result in the formation of a wet area around the machine, it

should be thoroughly dried before proceeding. - Remove the fixed and rotary blades; - Disassemble the machine into its main sections; - Separate machine components on the basis of their type (e.g. plastic, metal, etc.)and dispose

of them at a sorted waste collection plant in your area.

IMPORTANT Observe all the regulations in force in the country of installation of the machine with

regard to the disposal of used machinery.

10.1 GRANULE TRANSPORTATION INSTALLATION WITH SUCTION SYSTEM

Fig. 10-1 - On request, all the granulators "SERIES

N40" can be provided with a granule suction system consisting of:

N.1 cyclone, Ref. "1" - Fig. 10-1, provided with filter and installed on a proper support located on the rear side, Ref. "2" - Fig. 10-1;

N.1 suction unit, Ref. "3" - Fig. 10-1,

provided with connection pipe to the cyclone;

N.1 granule extraction cone, Ref. "4"

- Fig. 10-2, that replaces the normal collection box.

Fig. 10-2 - This system is a practical accessory that

allows emptying the granulator drawer. It offers therefore the possibility of accumulating the whole product in large containers without any operator’s intervention.

- To get a good operation of this system,

comply with the following rules: 1) Stop the suction fan when the cutting

chamber of the granulator is completely empty only.

2) When starting the system, always start first the suction fan and then the granulator In the event of a stop immediately before restarting the plant, empty the granulator cutting

chamber completely and remove all granulated material completely from the granules extraction cone, Ref. "4" - Fig. 10-2, then restart the vacuum unit and subsequently start the granulator.

To remove the granules extraction cone proceed with the following sequence of operations: open the granulator lower door and pull the granules extraction cone towards the machine exterior, see fig. 10-2.

10 - 4

ATTENTION Before refitting both the front and rear fixed blades, clean holder carefully with a rag.

N.B. To refit sharpened fixed blades, the same screws and washers that were holding it on

can be used. When new fixed blades are being fitted, however, it is necessary to replace the screws

and washers with new ones of the same strength.

NOTE Tightening torque for fixed blade bolts: Mod. G40-50 = 20,2 kgm (202 Nm) Mod. G40-70/G40-90 = 30,2 kgm (302 Nm)

IMPORTANT All screws must be moistened with a film of lubricating oil to prevent jamming.

Carefully clean holder of fixed blades before refitting them. Restore the correct distance with the rotating knives as already described in paragraph 7.4, then lock the screws with a torque wrench. Remove the protections previously fitted to cover the cutting edges of the rotating knives and then rotate the rotor slightly, checking through one complete revolution, the exact distance between the rotating knives and the fixed knives. Return the filling hopper to its lowered position and close the front panel, re-tightening the fixing knob. Re-install the fuses in the line supply panel and restart the granulator by setting the MAIN SWITCH to "ON" and pressing the start button.
