Pin Mills
Pin Mills are also referred to as Centrifugal Grinding Mills. It provides a simple, inexpensive means of grinding, sizing, de-agglomerating and homogenizing material, and can be employed as an effective infestation destroyer. It yields particle sizes down to 325 mesh and is primarily used for friable materials. Available in #304 stainless steel, sanitary, abrasive resistant and standard carbon steel design, the Centrifugal Impact Mill operates without screens, hammers, knives or rolls.
Operation
Metered material is gravity fed through the centrally located inlet of the "stator disc". Centrifugal forces accelerate the material and launch it into the impact zone. The action created by the stationary and rotating pins creates a "treacherous path" for material to pass through. Achieving the desired tight particle size distribution is obtained by controlling the rotor speed. Varying the rotor speed between a few hundred rpm up to 5400 rpm provides the flexibility to use the machine as a coarse grinding or de-agglomerating unit as well as a fine grinding mill. Whether the machine is used for cracking wheat, grinding iron oxide powder, creating powdered sugar or as a cellulose fiber conditioner, large production throughput rates can be attained in an inexpensive, compact machine. It also fits in neatly after most flaking operations.
