Ball Mill Grinding Theory

The proper operating speeds of ball-mills vary inversely as the square-root of the diameters. The proper operating speed of a ball-mill increases as the size of the ball load increases. Due to interference between the balls, the volume of the charge should not be over 60 per cent, of the volume of the mill.

Comminution

For comminution of finer particle size ranges (20mm > P 80 > 30 μm) machines like the ball mill, vertical roller mill, hammer mill, roller press or high compression roller mill, vibration mill, jet mill and others are used. For yet finer grind sizes (sometimes referred to as "ultrafine grinding"), specialist mills such as the IsaMill are used.

Hydrocyclone Working Principle

The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE.
