Grinding Mills Grinding - the last stage in the process of comminution is a combination of impact, chipping and abrasion. It can be done dry or in suspension in water. It is performed in rotating cylindrical steel vessels which contain a charge of loose crushing bodies - the grinding medium- which is free to move inside the mill, thus comminuting the ore particles.
