Crushing in Mineral Processing

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.

Milling Process. Sugarcane can be harvested by way of hand cutting, machine cutting, or mechanical raking. Several mills consisting of 3 rollers are run in series, with hot water being added after the first crushing. This process squeezes out the sugar, and the plant material left over is known as bagasse (bə-găs). The boilers are
