The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the ...

In any mill, the rate at which the surface of any ball decreases is proportional to its surface. Since the rate at which a ball loses weight varies as the work done upon it in the mill, it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball. This is seen to be Kick's law.

The withdrawal of pebbles from the primary milling circuit will cause the feed rate to a primary mill to increase. If one considers both milling stages, the comparison with ball-milling was based on the same final rate of production from the ball-mill(s). Hence, the required rate of production by the primary mill will be reduced (by about 7%).

It is observed that to increase the selectivity of particles it is necessary to reduce the grinding media size. The experiments are carried in stirred ball mill (SBM) with ball size of 1.5mm and tip velocity 7.6m/s. The product obtained from industrial ball mill at six hours of grinding was taken and further milled in SBM.

However, stickiness can also increase with higher fineness. Material with high stickiness creates problems in all aspects of the grinding process, including feeding (e.g., making metering into the mill difficult), grind-ing (e.g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the
