Crushing and Pulverization of Ores - Study Page

The crushed pieces of the ore are then pulverized (powdered) in a stamp mill . The heavy stamp rises and falls on a hard die to powder the ore. The powdered ore is then taken out through a screen by a stream of water. Pulverization can also be carried out in a ball mill. The crushed ore is taken in a steel cylinder containing iron balls.
