Impact Pin Mill
Centrifugal impact pin mill is a compact, high speed impact mill capable of fine size reduction specially designed for chemical, pharmaceutical and food application. Material is fed into the grinding chamber via the central inlet of the opposing stationary disc by gravity or screw feeder. High speed rotation of the inner disc creates centrifugal force that accelerates bulk material moving from the center to the periphery of the discs at high speed. As materials pass through a path of intermeshing rows of rotating and stationary pins, grinding is done by strong impact and shearing between the pins. The centrifugal force or air stream generated by draft fan force the product go through a filtering sieve which is around the grinding chamber to get required particle size. Different particle size is determined by the speed, number, type of pins and hole size on the sieve.
