Definition of pulverization. "Pulverization" (comminution, crushing, grinding) is the process of applying an external force to a (solid) material of a certain size to destroy it and reduce it into pieces that are smaller than the original size. Pulverization has long been done for many materials, including ore, glass, ceramics, grains ...

First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher "breaks it and the fine material produced will drop through the gap between the mantle and the liner as it opens. The coarse material that can't fall through will remain to be crushed with the next gyration.

technological processes. One thing is certain: the process of crushing entails high energy consumption (Tęsio- rowski [15], Numbia et al. [19]), and wear off the crush-er components (Mierzwa et al.
