D6A & M5A FITZMILLTM

FitzMill™ comminuting machines arerecognized worldwide as theindustry standard for precisionparticle size reduction. The D6AFitzMill is ideal for use in continuousor batch production, research, andproduct development as thefollowing features highlight:

• Wide range of processpossibilities

• Predictable and consistent end results

• Easy to clean

• Compact GMP design

• Directly scalable to larger units

• Quiet operation

• Low dust and low heat

The in-wall and on-wallconfigurations of the VFS-D6Aare designed to contain the drivemotors in a separate room ortechnical area. This leaves only afew easily disassembled productcontact parts in the process area.

Metered Feed

The metering feed system of theVFS-D6A can greatly enhance themilling process by providingimproved product uniformity, andthe elimination of operatorvariables, as well as completeprocess repeatability.

In-Wall Design

(VFS - Variable Feed Screw)

Gravity Feed

The FitzMill process chamber is often fed simplyby gravity. The S-Pan and VHP D6As, alongwith the SPV Cabinet Base D6A provideoptimal GMP when gravity-fed milling is desired.

The RP Cabinet Base M5A incorporates the feed panand feed throat in one piece. The cabinet base designalso integrates the base and controls into a self-containedportable unit.

D6A also available in this configuration.

The VHP D6A featured above employs a large feedpan which is separate from the feed throat. The VHPdesign is ideal for efficient feeding of large material.

Cabinet Base M5A With RP Throat

Benefits of This New PatentedSystem:• Backpurge cartridge is effective at keeping filters clean without pressurizing process area

• Inert processing with atmosphere monitoring andcontrol is possible with minimal nitrogen consumption(ATEX compliant)

• PCS components are easy to clean and filters are disposable

• Minimal internal surface area with vertical orientation reduces product hang-up and loss

• WIP System available to wet product surfaces after processing

The Product Containment System (PCS) isdesigned to contain the product inside the processcomponents in order to prevent airborne dust fromescaping into the atmosphere. A second objective ofthis system is to facilitate operation in an inertenvironment. The method used to contain the productis similar to isolator technology. The process area iskept under a slight negative pressure to ensure thatno powder migrates to the outside.

Fitzpatrick has incorporated many exclusive featuresto ensure a tightly sealed machine, which is critical tothis design; however, a number of other componentsare also required to allow for effective operation. ThePCS uses several primary filters in the machinedischarge. These filters are connected to a vacuumsystem which maintains the proper condition insidethe processing chamber. A Fitzpatrick exclusivebackpurge cartridge (patented) is utilized to drawprocess gas in from one filter, in order to backpurgeand thereby clean another filter.

The VFS D6A PCS LB includes the electricsmounted in an enclosure that is integral to the machine base. The upper section isavailable with an adjustable height feature.

CONTAINMENT AND INERT PROCESSING

The RV M5A PCS FitzMill Shown In Bin-to-Bin

Configuration

Isolator Designs Available

The RV D6A PCS with remote electrics (controls notshown) includes a rotary valve feed system.

The process area is well-sealed and operatingunder a slight vacuum. The containment challengeis to ensure product doesn’t escape the system as itis brought to and away from the machine. This isdone through the use of containment valves or othertechniques as required to feed and discharge theproduct in a contained system.

Isolator Mount Available For Additional Safety

For situations where additional levels of containmentare required, contained equipment can be customizedto facilitate installation in Barrier Isolators, LaminarFlow Booths, or other containment systems. Thesetypes of installations are particularly convenient forcontaining laboratory equipment where componentsare relatively small and products being processedmay be unknown.

RV - Rotary Valve

Bar Rotor

The comminuting bar rotor operatesat a low speed and reduced energylevel. Creating a sifting action closeto the screen without contact, the barrotor gently granulates and delumps.

Screen Variations

An extensive selection of screentypes and sizes accommodatesyour particle size requirements.Screens are available withopenings from 0.30mm/.012into 38mm/1.5in, with round orsquare perforations, diagonal orstraight slots, or in wire mesh.

FLEXIBLE

Rotor Features

D6A versatility is enhanced with itsone-piece, reversible knife/impactrotor. The impact edge pulverizes,emulsifies and purees, and the knifeedge granulates, chops and sizes.Switching from knife to impact isaccomplished simply by reversing the rotor.

EASY TO CLEAN

VFS-Feed Hopper

The metering screw and hopper whichprecisely controls the feed rate to theVFS-D6A disassembles into fiveseparate components for quick andeasy clean- up and assembly.

A single operator can disassemble the D6A quickly and easily forthorough cleaning.

Process chamber disassembles into seven easy-to-clean components.

Clean-Up & AssemblyEach disassembled componentweighs less than 10kg/22lbs.Complete disassembly for inspectionand cleaning can be accomplishedby a single person, in minutes.

In the 1930s, the Fitzpatrick Company pioneered thedevelopment of particle size reduction technology.20,000 machines and 10,000 customers later,Fitzpatrick upholds that tradition of innovation bycontinuing to manufacture the world’s most advancedprocessing equipment.

Pharmaceutical, Chemical, Food, Plastics and otherindustries utilize a wide range of Fitzpatrick machines,including FitzMill™ Comminutors, and Chilsonator®Roll Compactors. Each Unit is built to stringent qualitystandards to operate under the most demandingmanufacturing conditions.

The Fitzpatrick Company maintains manufacturingfacilities, test laboratories, and service/support officesin Elmhurst, Illinois.
