Prater mills are widely used throughout the process industries for manydifferent particle reduction applications requiring high capacities, power
efficiency and uniform particle size. All six models feature our exclusive
Full Screen design, a proven system that ensures use of the entire available
screen area, enhancing end product quality and equipment productivity.
Screens are strategically placed where extensive testing has shown themajority of grinding takes place, increasing throughput capacity without
increasing power requirements. The design improves access to working
parts simplifying screen changes.
The center feed and fully symmetrical rotors distribute the productacross the full width of the screen area for even hammer wear, thisallows the rotor to be reversed so that both edges of the hammers
can be utilized before replacement is required.
Correct clearance between hammers and screens is maintained bymounting all screens in heavy-duty frames. Rotors are wider for varied
hammer arrangements, and are all supported between durable pillow
block bearings. These proprietary design factors combine to provide acontrolled, uniform granular grind with the benefits of easy maintenance.
