Pin Mills

Munson's Pin Mill, or "Centrifugal Impact Mill," reduces bulk materials into narrow particle size ranges without the need for screens, hammers, knives or rolls. Instead, it relies on material impacting hundreds of pins thousands of times as it travels from the center to the periphery of the milling chamber. The chamber consists of an outer stationary (stator) disc containing circular rows of pins that alternate with concentric rows of pins on the inner rotating (runner) disc.
