HOSOKAWA BEPEX Size Reduction TechnologyProcess Solutions for Granulation Requirements

BEPEX offers a variety of techniquestailored to meet the requirementsof your business.

PharmaceuticalsFoodChemicals

Our technology increases and

homogenizes the bulk density ofmaterials, breaks down agglomera-tes and flakes from roller compacti-on or other processes. Granulatingthese by-products improves flowproperties.

Materials of Construction,FinishesAlthough all of the product contactparts of the BEXMILL series and theFlake Crusher series are constructedfrom stainless steel, you can requestcustom construction from other

materials such as Hastelloy. The Pre-Crusher series can also be construc-ted from carbon steel.The following finishes are available:

Ceramic liningsBrush finishedMechanically and electropolished

Controls and DrivesBEPEX also offers several optionsfor the control of these machines.Your choice ranges from manualspeed controls through to variablespeed drives for precision motoradjustment with integrated

feedback loops.

The machines are suitable for allATEX requirements.

BEXMILL BMHigh Capacity and Versatile Production

The BEXMILL BM series offers youa variety of production capabili-ties. Our machines can handleboth small laboratory require-ments and large production ratesof up to 8 tons per hour. Since our

machines are versatile, they canbe delivered with many accesso-ries and in different configura-tions. For example, machines areavailable in both portable orstationary designs.

The BEXMILL can be operated in acontinuous or batch process.Granulation takes place betweenthe conical rotor and screen. Softto medium hard flakes in a varietyof sizes can be granulated in one

pass.Your required particle size can beachieved using a variety of inter-changeable screens. This gentlesize reduction avoids productdamage and generates a minimal

amount of fines.You can change screens quicklywithout any tools to avoid costlydowntime. Either way, theBEXMILL maximizes processeffectiveness while reducing

process costs.

BEXMILL BMEasy Clean Design

The combination of the rotorspeed and screen selectiondetermines the final particle sizedistribution (a, b). The critical gapbetween the rotor and screen canbe adjusted manually or automa-tically. The rotor is designed forlong life and maximum perfor-

mance. Rotor seals are alsoavailable with air or nitrogenpurging.

The BEXMILL is the perfectmachine for your GMP facility toprocess pharmaceuticals.

All product contact gaskets andseals use FDA approved materials.

Each unit can be custom designedto accommodate a wide variety ofupstream and downstreamconnections. For example, inletsand outlets of the mill can bedesigned with beaded collars, tri-clamp connections or vacuumconnections (c).

Product contact areas can bewashed using CIP systems (d).

A telescopic outlet (e) can be usedfor in-line fixed installations. The

telescopic transitions are flangedto the mill for a dust tight seal. Allflanges are machined. Siliconegaskets are used between flanges.The design eliminates the needfor a fixed pipe system betweencomponents. It also facilitates thescreen changing process.

Flake Crusher FCFine, but not Too Fine

Principle of OperationThe rotor cuts the materialthrough a screen surface using arasp screen or a hole screen. Thethroughput, particle size rangeand crushing intensity aregoverned by the rotor speed,while the upper limit of theparticle size is dictated by thescreen. Final screening of theproduct to remove oversizedmaterial is not necessary.

The ConstructionThe rotor is installed in a dust-tight welded casing. The screensare fastened to a supportingbasket. Two eccentric camt e n s i o n i n g d e v i c e s a l l o w

adjustment of the screen basketrelative to the rotor for maximumgrinding efficiency and screenlife.

Disassembling and CleaningAll parts in contact with the productbeing processed, including the rotor,screen with basket and cam tensio-ning devices, are easily disassembledfrom the front. Cleaning and disas-sembly can be done in a few minuteswithout the need for removal of theFlake Crusher from the process.

Connection with Other Equipment The Flake Crusher makes a dust tightconnection with other equipment inthe operation. For cleaning only thequick-acting clamping device isopened. The Flake Crusher is movedto the front, out of the operatingarea, on rails.

AccessoriesThe Flake Crusher FC can be equippedto suit each individual application.

Pre-Crusher PCLow Energy - High Yield

Principle of OperationMaterial is drawn in continuouslythrough the two synchronouscounter-rotating rolls . Theperipheral speed is set to matchthe throughput. A very lowgrinding energy consumption aswell as the synchronous speed of

the rolls assures a nearly dust-freecrushing process.

The ConstructionAll Pre-Crushers PC use a weldedcasing with external bearingdesign for low maintenance andhigh reliability. Various materialsof construction are availabledepending on the application.The separately driven crusher rollsutilize an electric drive withoutthe need for gearing.

Crushing Roll DesignPins (Model PC-P)The design employing wearresistant pins is used for theprebreaking of thick flakes andcoarse feed material. Thematerial is crushed into piecesof approximately 20 to 30 mm.Discs (Model PC-D)The design employing discs isused to crush thinner flakes to

a final size of less than 5 to15 mm.Hardness of pinsShape of laser-cut discsRequirement of hardfacingCrusher gapTypes of materials ofconstruction

Our analyticallab can quickly analyse theproduct. The results of our testsare not only the production ofsamples or machine configura-tions but also an individual systemdesign and complete processengineering for your needs.

Development and DesignTo accommodate our technologyto your application we usemodern CAD and our ownfabrication. We develop andmanufacture new machines,plants and processes to be able toproduce granules with speciallytailored properties. Due to theintensive and world-wide co-operation especially with sister

companies and research instituteswe have a high developmentpotential at our disposal, whichwe can offer for your application.

ValidationWe can validate both machinesand plants according to yourgiven standards (IQ and OQvalidation).

Control and AutomationProcess Logic Control (PLC) isstandard and can easily beinterfaced with other mainprocess control and data loggingsystems on your plant. Our

COMPACT CONTROL enablesprocess automation and visualisa-tion including process monito-ring, data gathering and diagno-sis of errors.
