2.5 NoiseThe machine belongs in the category of plant equipment whose noise emissi-ongenerallyreachesalevelof80dB(A)ormore(asdefinedinDIN45635).

The noise level generated by the machine is governed by various factors, e.g. type of product, site of machine installation, etc.

It is therefore impossible to quote a generally valid sound pressure level.

When operating the machine within the European Union, the EC Directi-ve2003/10/EC (dangers caused by noise pollution at the workplace) must be observed,andwhenoperatingthemachineinGermany,theregulation on noise – BGV B3 – issued by the relevant trade association must also be observed in addition.

In other countries, the respective national standards and directives must be observed.

If the noise emission exceeds the max. level of 85 dB(A), the directive RL 2003/10/EC dictates a number of mandatory measures, among them the use of suitable ear protectors.

The main source of noise with this system is the vacuum cleaner. By applying suitable measures, e.g. screening off the vacuum cleaner behind a noise-absorptionpanel,thesoundpressurelevelcanbereducedsignificantly.

2.6 WorkplaceThe workplace for the operating personnel is in front of the installation table.The workplace must be kept clear and uncluttered at all times.

4 Preliminary Procedures

4.1 Transport / storage4.1.1 Transport

TransportThe air jet sieve must not be knocked, shaken or thrown through the air during transport.Ifthetemperaturefluctuatesstronglyduringtransport(e.g.duringairtransport),the air jet sieve must be protected against condensation to prevent damage to the electric components.

When transporting the machine, the 89/655/EEC directive on the use of technical equipment or the corresponding national standards and directives must be observed.

PackagingThe packaging was selected to suit the means of transport and conforms with the prevailing packaging directives.

If returning the air jet sieve for servicing procedures, always use the original packaging. Liability reasons dictate that we are unable to accept an air jet sieve and accessories that are returned to us in non-original packaging.

4.1.2 Intermediate storageIf storing the air jet sieve and individual units for prolonged periods, make sure that:

– they remain packed in the original packaging – they are stored in a dry room– they are protected against dust, moisturem, strong sunlight and the ele-

ments, and that– the temperature of the storage area ranges between 0 and 50°C.

Becauseoftheriskofdamagecausedbycondensation,avoidstrongfluc-tuations in temperature.

4.1.3 Unpacking – keep the original packaging material!Check the delivered goods including the accessories for completeness.

If the delivery is incomplete or if transport damage is visible, contact the for-warder or HOSOKAWA ALPINE immediately.

Keep the original packaging material for the event that you need to return the air jet sieve (see Section 4.1.1).

5.1.2 Test sievesCleaning and inspection intervalsA basic cleaning and rudimentary inspection for damage to the sieve gauze must be carried out before and after every single sieving operation.

In addition, the test sieve must be thoroughly cleaned and inspected in detail at regular intervals. The intervals are dependent on the products to be analysed and the sieve mesh width. As a rule of thumb, the following applies:

– Test sieves < 63 µm: after every 5th sieving process

– Test sieves < 150 µm: after every 10th sieving process

– Test sieves > 150 µm: after every 20th sieving process or as necessary.

Cleaning the test sievesThe cleaning method is dependent on the mesh width, the degree of soiling and the product.

See also DIN 66 165, Parts 1 and 2 as well as ISO 2591-1.

Inspecting the test sievesVisually inspect the test sieve for damage and dirt residues after cleaning and drying.

Inspect the test sieves for damage to the sieve gauze and for any clogged particles which were not removed during cleaning. The following inspection procedures are in general use:

– Visual inspection

Hold the test sieve up against the light, e.g. in front of a window or a light table.Itisadvisabletouseamagnifyingglassinthecaseoffine-meshsieves.

– Comparison sieving

Prepare a relatively large sample of a product that has a known particle size distribution. It is essential that initial determination of the particle size takes place with an air jet sieve equipped with a new test sieve. The sieving parameters must be identical for the reference sieving and the comparison sieving.

– Sieve exchange

Especiallywithfine-meshtestsieves,itisnotalwayspossiblewiththemeansavailabletodetectallflawsordefects.Inordertoguaranteetheperfect condition of the sieve, it is preferable to exchange the test sieve in this case.

– Useofsievegauzesasdefinedinthestandards(usuallyDINISO3310)

This method is actually intended for the manufacture and assembly of test sieves. It is too complicated to be applied regularly by the user.

5.2 Regular inspections5.2.1 Inspections to be carried out by the user

Pay attention to the safety regulations in Section 2.4!

To permit conclusive and reliable measurements, the air jet sieve must be checked regularly for function.

The components must be checked by skilled personnel every 500 operating hours or more frequently if the product being sieved is strongly abrasive or tends to cake. The user is charged with determining the inspection intervals and with carrying out the inspections. It makes good sense to keep a record of inspection procedures.

The following must be checked:• Airjetsieve:

– The nozzle must rotate during sieving. This can be checked during sieving by observing the product for movement. The nozzle aperture must be kept clear; clean off any clogged particles.

– Timer: check the accuracy with a stop watch.

– Underpressure measurement: check the zero indicator with the air jet sieve switched off.

– Adapter rings (A4.4): check the seals for damage.

– Sensorfilter:visualinspectionforsoiling(Section5.1.7).

• Testsieves – Check the test sieves for soiling and defects, clean or exchange if

necessary (see Section 5.1.2).

• Vacuumcleaner–payattentiontothehandbook!

– Check the generated underpressure: repair or exchange the vacuum cleaner if the operating pressure falls short of the setpoint value even afterfine-adjustmentoftheworkingpressureandexchangeofthefilterbag, theabsolute filter element and/or the filter fabric insert (order-specific).

– Checkthefilterbagforpermeability;exchangeifnecessary.

1 Sieving Methods1.1 Sieving method overview

The e200 LS Lite differentiates between the standard and the Swiss sieving method.Each method also knows the difference between sieving “without“ and “with“ consideration of the weight of the sieve, i.e. “without sieve tare“ and “with sieve tare“.

The method to be used should be determined at the time of defining the set of sieves (Page B-21). If a sieving process is carried out without a set of sieves, the settings in the configuration menu (Page B-36) apply.

1.2 Standard method1.2.1 Fundamental sequence

With the standard method, first of all weigh a sample quantity, tip it onto the finest test sieve, sieve it in the sieving machine and then weigh the remainder of the sample batch. The difference in weight corresponds to the undersize at this mesh width.Repeat this procedure with the remainder of the sample batch using the next largest test sieve in each case.The software program enters the measured values automatically into a table and converts this table into a graph.The dialogue windows guide you through the entire sieving sequence.

Dependent on whether you weigh the sieve residue without or with the test sieve, the program differentiates between two different sieving sequences:

Standard method without sieve tare Fill the remainder of the sample batch from the test sieve into the weighing pan and weigh it. Any residues left on the test sieve lead to analysis inaccuracy.

Standard method with sieve tareDependent on the measuring range of the balance, you can weigh the entire test sieve including the remainder of the sample batch after each sieving process. The empty weight of the test sieve (tare) must be entered into the system beforehand in order that the weight difference can be determined.

1.3 Swiss sieving method1.3.1 Fundamental sequence

The Swiss sieving method is characterised in that every sieving operation is always carried out with a full batch of weighed material.With the Swiss method, you need a complete batch of weighed material for every sieving operation. Fill each sample into the test sieve and perform the sieving process. During sieving, it is not necessary to transfer the material to another sieve.

Dependent on whether you weigh the sieve residue without or with the test sieve, the program differentiates between two different sieving sequences:

Swiss method without sieve tare Fill the remainder of the sample batch from the test sieve into the weighing pan and weigh it. Any residues left on the test sieve lead to analysis inaccuracy.

Swiss method with sieve tareDependent on the measuring range of the balance, you can weigh the entire test sieve including the remainder of the sample batch after each sieving process. The empty weight of the test sieve (tare) must be entered into the system beforehand in order that the weight difference can be determined.

Advantages– Every test sieve can be prepared in advance with a full batch of weig-

hed material (e.g. in the case of toxic substances under application of a suction unit).

– During sieving, it is not necessary to transfer the material to another test sieve. The residue on the test sieve is not needed for other sieving operations (advantage if, for example, the material is hygroscopic). Any residues in the test sieve do not influence the result provided that the test sieve is always weighed as well at the same time.

Disadvantage– The batches of weighed material must be prepared in advance for every

sieving operation (max. difference between batches ± 5%).

If sieving processes need to be repeated several times, it makes sense to generate a sieve set. This guarantees use of the same parameters for every sieving process, thus making them comparable.

The following values are stored in a sieve set:Main parameters:– Automatically generated number– Sieve set name– Generator– Method– Comments– Calculation method: residue or undersize– Sieving aids– Batch weightFor every test sieve: – Mesh width– Underpressure– Sieving time

1.1 Sieve mesh widthsThe sieve mesh widths which need to be used are usually dictated by market specificationsorprocess-specificreasons.Thefreedomtochoosethesievemesh widths is often only possible within the framework of in-house product specifications.

The particle size distribution of a bulk material is characterised by the position and steepness as well as by the top-size particles. With two sieving processes closetothedistributiondensitymaximumandonesievingprocessinthetop-sizerange,theparticlesizedistributionisinmanycasesalreadydescribedadequately.Butiftherequirementsarehigher,e.g.ifasmallfinesfractionisdesired,afurthersievingprocessintheundersizerangemustbecarriedout.

1.2 Batch weightTheamountofmaterialtobeweigheddependsonthefinestsieveinthemeshscale. With a solids density of Ps 2650 kg/m3(limestone),thevaluesinTable1.0-1 are applicable. The conversion to other solids density values is linear (double the density = double the batch weight).

1.3 UnderpressureThe underpressure needed for a sieving process is determined by the mesh widthoftheinsertedsieve.Generallyspeaking,thisvalueshouldbebetween5000and7000PascalforØ-76-mmmicro-precisionsieves,andbetweenthevalues shown in Table 1.0-1 (min. values) for standard sieves.

4 The ALPINE Air Jet Sieve in Quality As-suranceWiththeairjetsieve,Alpineoffersawell-knownanduniversallyaccrediteddevice for particle size analysis. It has been the analysis unit of choice in R&Dandproductionformanyyears,andislegallyestablishedinanumberof different product standards.Withrespecttoqualityassurance,thetime-provenprincipleofparticlesizeanalysiswiththeALPINEairjetsieveisespeciallysuitableinthecontextofcertificationasdefinedinISO9000ff.

The following points are described in other sections:

– Details of machine inspection: see Part A

– Cleaning and checking the sieves: see Part A

– Determining the sieving parameters: see Section 1

4.1 ParticlesizedefinitionJust about all the particles processed in industrial processes have a particle shape that deviates from the ideal spherical form. This leads to the necessity ofdefiningtheparticlesizeofnon-sphericalparticles.Thereareanumberofdifferentpossibilities,butgenerallyspeaking,theparticlesizeisdefinedbymeansofthemeasurementprinciple.Inthecaseofairjetsieving,thismeans:a particle is considered a certain size if it passes through the apertures of a sieveofthemeshwidthinquestionfreely,wherebythelargestdimensionofthe particle can by all means be larger than the mesh width.

4.2 Quality assurance requirementsThetaskofqualityassuranceduringthemanufacture,handlingoruseofbulkmaterialsistoguaranteethedefinedanduniformpropertiesoftheseproductsandanyfollow-onproducts.Inthemain,thefollowingdemandsaremadeofthe measuring equipment used in this application:

ReproducibilityThis is thedifferencebetween two results,whereby identicalsamplesaremeasuredat identicalsievingparametersbutatdifferent times. In [1], thecorrelationsare investigateddependent on thebatchweight, sievemeshwidthandproductfineness.Typicalnumericalvaluesasafunctionoftheseparametersliebetween0.2and1.5%sieveundersizefraction,see[2].

ComparabilityThis is thedifferencebetween two results,whereby identicalsamplesaremeasured at identical sieving parameters using different sieving machines or the same sieving machine with different sieves of the same mesh width. Inadditiontothefaultsfromthereproducibility,faultsoccurhereoccasionedby the limited precision of the test sieves. The permissible deviations of the meshwidthsareenshrinedinthestandards[3].Forexample,fortheaveragedeviation in onedirectionof the sievegauze (dimensionY), the followingvalues are permissible:

32 µm-sieve: 2.7 µm 100 µm-sieve: 5.0 µm 315 µm-sieve: 12.0 µm

4.3 Individual operating pointsIt is important to prepare an analysis directive for every product. Besides thesievemeshwidthstobeused,thisdirectivemustincludetheassociatedsievingtimes,dispersingagentsanddocumentationrequirements,thisad-vantageouslyasaformtobefilledout.Thesievinganalysisitselfmustbeexecutedbytheoperatorwithduecare.

Sampling / sample preparationSampling and sample preparation (sample splitting) must take place in accor-dancewithadefinedmethod,andthisinturnmustbeincludedintheanalysisdirective.

UnderpressureThe underpressure must be within the range stipulated for the respective sieve mesh width.

Sieve selection / sieve insert errorSelection of the sieves is an integral part of the analysis directive. Prevention of sieve insert errors is the responsibility of the operator.

Spillage of sample materialIt is the operator's responsibility to prevent spillages. If product was inadver-tentlyspilledduringsampletransfer,thecompletesievinganalysisincludinganyfiner-meshsievinganalysescarriedoutwiththissamplemustberepeated.

Sieving timeThestandardtimeisspecified intheanalysisdirective. It is theoperator'sresponsibilitytocomplywiththespecifications.

Dispersing agentsIfthesievingprocesscallsfortheadditionofadispersingagent,thismustberecordedintheanalysisdirectivewithdetailsofthefrequencyitisadded,theamountandtheexactname.

Sieve cleaningThe analysis directive must also contain information on the length of the intervals between cleaning and on the type of cleaning agents to be used. Irrespectiveofthis,anysievesthatarevisiblysoiledmustbecleaned.
