A mixed material, having a humidity rate of %, moves from the material silos into the raw mill. The kiln exit gases are conditioned in the gas conditioning tower to leave at K, for preheating and drying the feed to the raw mill. In the mill, the mixed and dried materials exit as raw meal with a humidity rate of %, after grinding.

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.
