MPS mill (rollerrace) model. The most significant difference between the MPS and Emill designs is the grinding mechanism. The MPS mill uses a three rollerrace system instead of the 10 ballrace system deployed in the Emill. The elutriator zone in the MPS mill also appears to be closer to the air classifier entry area.

This article focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for generalpurpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.
