The mill also includes the processes of attrition and impact, although these actions are limited if the material is easily reduced by cutting and the screen limiting discharge has large perforations. The mill consists of a rotating shaft with four attached parallel knives and a screen occupying one fourth of the 360 degree rotation.

Pressure drop across a 4 stage preheater used to be 500 to 550 mmwg. Any increase in number of stages resulted in additional pressure drop which unfavorably offset gain in fuel efficiency. Therefore cement industry continued for quite some time with 4 stage preheaters till cyclones of low pressure design were developed.
