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 ...Web
