Centrifugal Impact Mill

June 9, 2009
This 24-in. dia. sanitary stainless steel centrifugal impact mill, or pin mill, for dry or wet bulk solids provides fine-to-coarse grinding of friable materials into controlled particle sizes down to 325 mesh, as well as lump breaking and conditioning of fibrous materials. High-speed rotation of the inner “stator disc”-the only moving part contacting material-creates centrifugal force that accelerates bulk material entering the central inlet of the opposing stationary disc. As material travels from the center to the periphery of the discs at high speed, it passes through a "treacherous path" of five intermeshing rows of rotating and stationary pins, with the desired tight particle-size distribution obtained by controlling the infinitely variable rotor speed.
