In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Efficient screening is the quickest return on investment within your plant. Although outshined by processes that physically transform a material stream such as size reduction or color sortation, proper screening optimizes all these processing steps. Because the effect of screening is less observable, it is often overlooked.
