Comminution - an overview | ScienceDirect Topics

Comminution by grinding (or milling) is perhaps the most obvious way of attempting to increase the surface area of a given mass of solid. With some layer structures such as clays and graphite, an appreciable increase in specific area can be achieved by prolonged grinding ( Gregg, 1961 ), but this is not on the scale required to give a highly ...

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. Less abrasive and softer rocks or stones ...
