Milling is among the most energyconsuming technological stages of copper ore processing. It is performed in mills, which are machines of high rotational masses. The start of a mill filled to capacity requires appropriate solutions that mitigate the overloading. One method for increasing the energy efficiency of ball mills is to optimize their drive systems. This article looks at two variants ...

In the copper mining industry, ball mills are primarily used for grinding copper ores into a fine powder, enabling further beneficiation processes. The size and efficiency of a ball mill directly influence the liberation of valuable minerals from the ore and the subsequent copper recovery. Functions of Copper Ball Mills:

The Function of a Ball Mill . To perform its functions, the ball mill operates on the principle of impact and attrition. This principle entails that the balls are dropped from near the top of the shell in order to bring about size reduction impact. The major components of the ball mill include a shell that is hollow and is suspended on its axis ...

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

Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semiautogenous grinding (SAG) mill followed by a ball mill (two stage circuit).
