4 EASILY CONFIGURABLE FEED SYSTEM The <strong>Fitzpatrick</strong> feed system delivers material to the rolls utilizing a feed hopper, horizontal feed screw for metering material, and a vertical pre-compression screw for pre-compression, deaeration, and transport of feed material to the compaction rolls. The high speed vertical pre-compression feed screw(s) is very effective at deaerating a vast majority of powders. Even many low bulk density powders are able to be effectively conditioned for efficient compaction. This feed system design provides significant process advantages with few components to clean and maintain. In a few applications, the material characteristics restrict the ability of the entrained air to be vented from the system utilizing the pre-compaction screw alone. In these applications, the optional Vacuum Deaeration System is available to assist in drawing the entrained air from the product. Vacuum filters can be installed in various locations and a vacuum pump system is utilized to forcibly remove entrained gas from within the product. Process improvements can be dramatic with respect to both compaction efficiency as well as capacity. Optional Vacuum Deaeration System VACUUM PUMP SYSTEM Feed hopper includes agitator VARIOUS ROLL SURFACES AVAILABLE The cantilever design allows for easy removal of roll shells for cleaning or reconfiguration. The roll shells have water cooling capability. TWIN OR SINGLE PRE-COMPRESSION SCREW OPTIONS Twin pre-compression feed screws provide uniform force Single pre-compression feed screw
TWO-STEP CONFIGURABLE SIZE REDUCTION The most efficient method of reducing the compact to the desired granule is product dependent. Some applications favor the bar rotor and some favor the knife rotor as more effective. Both options are available on each machine so the optimum arrangement for every product can be configured. In either case, the initial breaker combined with the very large screen area of the secondary reducer provides for the most efficient size reduction. Bar rotor for slow speed “crushing” of compact Knife rotor for “in air” impact size reduction FULLY AUTOMATED CONTROLS • Automatic operation of all components from the operator interface • Fully instrumented with convenient display and logging of variables • 21 CFR part 11 compliant capable • Multiple layers of password security 5
