ball mills involved

The operating principle of theball millconsists of following steps. In a continuously operatingball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

Ball mills are also used for the particle size reduction of black powder, cement, fertilizer, silicates and even a variety of ferrous and non-ferrous metals. Ball mills are very similar in design and operating concept to rock tumblers, which used milling media to polish rocks in a rotating cylinder.

Overflow VS Grate Discharge Ball or Mill - Why Retrofit
Overflow VS Grate Discharge Ball or Mill - Why Retrofit

In the case ofball millsthese are the overflow type, semi-grate or intermediate pulp level discharge, and the true grate discharge. A general statement can be made that the closer the discharge is to the periphery of the shell, the quicker the material will pass through and less overgrinding will take place.

The high unit capacity SAGmill/ball millcircuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).
