Jul 01 2015 comminution in the mineral processing plant takes place in a sequence of crushing and grinding (andor milling) crushing reduces particle size of run-of-mine ore to such a level that grinding
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 platesurface less abrasive and softer rocks or stones
The difference between crushing and grinding in mineral processing both crushing and grinding are size reduction processes they are known as milling operations introduction the size reduction operation in the plant takes place as a sequence of crushing and grinding processes in crushing particles are reduced in size to such a level that grinding can be conducted while grinding allows
