what is the process of grinding rocks
Grinding Processes | SpringerLink
Grinding is the common collective name for machining processes that utilize hard, abrasive particles as the cutting medium. The grinding process of shaping materials is probably the oldest in existence, dating from the time prehistoric humans found that they could sharpen their tools by rubbing them against gritty rocks.

Crushing in Mineral Processing
2015-12-26 · 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.
