The working principle of ball mill - Meetyou Carbide
Therefore in the rolling ball mill the grinding efficiency is increased as the ball diameter decreases. It has been proven that the highest grinding efficiency can be obtained with a small ball of .mm diameter. However the ball diameter is too small to wear too fast and it is also difficult to discharge due to the small gap of the ball.

Effect of ball size and powder loading on the milling
In this figure the positive influence of the smaller ball size on the milling efficiency is drawn by an arbitrary negative slope with ball size rather than the dependency of d −3 because the dependency of d −3 is valid only in a stationary state of ball packing while the actual ball milling is a dynamic event taking place under the
Efficiency Efficiency Calculation Of Rock Grinding Mill-ball Mill
Ball Charge And Grinding Efficiency Grinding. The effect of low ball full on grinding efficiency is the throughput of mill will decrease with the time the p80 in the discharge of the mill will increase because of the high time of particle residence in the mill and for this reason the grinding will be lower efficient the power specific consumption will increase due to the lower feed
