FEEDMAX Conveying Equipment

FEEDMAX S3 Single Loader

Optimized single loader for flexible conveying of smaller material volumes of up to 120 kg/h in permanent operation.Peak performance of up to 250 kg/h.

Robust stainless steel construction All components in contact with material are made of stainless steel and are therefore perfectly suited for critical and abrasive applications.

Needle felt filter with cleaning Contains a sealed filter surface on the front face to avoid the protrusion of dust particles into the structure of the needle felt filter and therefore permits higher operating times. Temperature resistance up to 150 °C.

Wand Included in the standard package is a 780 mm long wand with air vents for the adjustment of the material load, as well as a 5 m PVC hose.

Extensive display Three digit, 7-segment display for timers and parameters, e.g. conveying time, as well as LED`s for the visualization of internal operating conditions.

Granulator operating mode Adjustable timer function for the emptying of a granulator regrind bin.

Proportional valve (Option) The proportional valve for the measurement of two components is externally attached to the material inlet. The control allows the selection of the measurement in percent and the number of material levels in the hopper.

Remote teach pendant (Option) Second teach pendant with a 3 m cable for remote access when the loader is mounted on blenders or tall machine hoppers.

FEEDMAX Primus Material Loader

FEEDMAXPrimus

FEEDMAX Primus is a single conveying unit. It is combining rugged construction,easy maintenance, highest process security, and ease of use. Optimized single loaderfor flexible conveying of smaller material volumes of up to 120 kg/hr.and peak performance of up to 250 kg/hr.

Robust stainless steel construction All parts that are getting in contact with the material are made of stainless steel; therefore the unit is perfectly suitable for abrasive applications.

Needle felt filter with cleaning To achieve a longer lifetime a needle punched felt filter was used. The sealed filter surface is ensuring that any intake and accumulation of dust particles is made impossible. This filter is never losing its shape, and it is held in position during the entire conveying cycle, ensuring an absolutely unproblematic buildup of vacuum.

Wand included

Self-explanatory display To simplify the handling of the conveyor, no special display (and therefore no voluminous menu navigation) has been executed.

Central Filter Stations for BS/6 and B Series

XS Filter 2-Stage filtration system

In first stage pre-filtration takes place by means of the cyclone effect and in the second stage, microfiltration occurs with a cartridge filter having 2.7 m2 of surface area.

Effective dust blow-off The filter surface is cleaned at a pulsed interval with compressed air and the dust blown into a dust collection bag.

User-Friendly The dust container can be removed during operation for emptying.

XM B Filter 2-stage filtration system

In first stage pre-filtration takes place by means of the cyclone effect and in the second stage, microfiltration occurs with a cartridge filter having 5 m2 of surface area.

User-Friendly The dust container can be removed during operation for emptying.

Choice of dust container The dust collection area is kept pressureless through a shut-off valve in the discharge cone of the filter and therefore allows the use of any dust collection container, e.g. a plastic bag.

Machine hoppers ranging in size from 3 l to 60 l guarantee the optimum volume of thematerial inventory to the total material throughput and thus, the performance of the entire system.

Stainless steel construction with sight glass Sight glass for abrasive uses as well as visual control of the material flow.

M7.2 Network Control System

M7.2 – IPC

The M7.2 network control system was developed for the administration of medium to complex network configurations with up to 320 network participants. Every participant is connected via a bus module to the network and can be configured for a specific task. This guarantees the maximum flexibility for the set up of customized material handling systems.

M7.2 – IPC/TeachBox Touchscreen The high-resolution Touchscreen simplifies user control, as well as the adjustment of process parameters and allows the user a comprehensive view of all attached units.

Line Server LS-A30T Provides for the control of up to 31 freely configurable bus modules, which can be connected in parallel to one CAN-Bus line. All functions which are available for the respective bus modules can be managed and controlled from the line server. A complete system can have up to 8 individual CAN-Bus lines.

Bus Module BM-4/4 Provides individual control of vacuum loaders, blower stations, central filters, dry air valves, purging valves, etc. Any function can be assigned to the 4 digital inputs and outputs of the bus modules and therefore, gives the system virtually unlimited possibilities of con- figurability for each particular application.

M7.2 – Connection to ERP Systems

CODEMAX – RFID Coupling Station

All relevant control data and parameters can be transferred to a company wide enterpriseresource planning (ERP) and process data monitoring (PDM) system via the open standard protocol OPC.

For the connection to a PDM system the M7.2 IPC control system is optionally equippedwith an OPC Server/Software, which provides for the communication between an external computer and the control system. A customer supplied OPC Client accepts the required data from the M7.2 control system and manipulates it internally. The data exchange happens via the Ethernet interface.

M7.2 – Networked Dryer

The M7.2 control system permits the connection of Drymax battery dryers with network cards to the central M7.2 control system. This allows the visualization of internal parameters and conditions on the generously dimensioned M7.2 control screen as well as the entry of temperature values for the various connected drying hoppers.

Connection of up to 32 Battery Dryers with 240 Drying Hoppers

Optimized Control Manages internal process of the dryer with failure analysis.

Dew Point Recording In the presence of a dew point sensor the actual values are captured and recorded over a 12 hour time period.

Management of Material Data Includes all drying hoppers attached to the networked dryer.

Central Error Display All error messages are transferred to the M7.2 control and centrally displayed.

The coded Coupling Station CODEMAX avoids the erroneous connection of the wrong material to the processing machine.

RFID Coding A transponder, working on the basis of “Radio Frequency Identification“ (RFID), permits remote recognition of a 64-bit identifier. By means of this technology, electrostatic charges which are inherent to the material conveying process cannot cause damage to the electrical components.

Applications

The modular design of the WITTMANN M7.2 hardware and soft-ware components and the arbitrary configuration enable the flexi-ble realization of various special applications, like the equal load and automatic switchover between vacuum pumps, the controlled assignment of material sources to machines or the throughput control of drying hoppers.

The use of high-quality installation material guarantees long life and trouble-free operation. The conveying of abrasive materials is accomplished preferably with glass elbows.

The high performance eMax and M7.2 network controls are desi-gned for highest durability. An important part of a highly reliable system is the professional and proper assembly of conveying tubes and connections.

”No two central material handling systems are equal.“ – As varied as production facilities, so are the requirements on the central material handling system.

Innovative product solutions are required more than ever before and can be achieved through the highly efficient WITTMANN controls.

”One-stop shopping.“ The extensive and innovative peripheral equipment program from WITTMANN allows the realization of demanding complete systems and the assignment of responsibility for the proper interaction of the single components. For service, a single phone call will cover the entire spectrum of WITTMANN products.
