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.
