Pin Mills use shearing and impact methods; however, with a faster tip speed of intermeshing pins when compared to a Hammer Mill. Centrifugal force brings the particle sizes to the grinding chamber's periphery for collection or further processing. The milling process will produce particle sizes down to ultra-fine micronized sizes +/- 10 µm.
