Ball mills are used to obtain a product size below 150 microns. With the rotation of the mill, collision and attrition forces grind down the material in the mill chamber. The balls act as the grinding media, where contact points are created with each other and the material is either crushed or ground.

Jet Mills. In jet mills the size-reduction of particles is carried out in a gas jet. The grinding gas (air or argon) is guided into the grinding chamber and accelerated in such a way, that product particles are carried along in the gas flow and impact against each other. Size-reduction is autogenous and contamination is therefore low.

The profiling of the shell lining plates creates the movement of the ball charge, which causes the grinding of the material. It is therefore essential for effective grinding in the mill and far more than just a wear part. The exact profile shape has to be defined depending on the ball sizes used, the rotation pace and the mill diameter.
