mineral ball mill and ball mill circuits

Grinding Circuit an overview ScienceDirect Topics

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 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).

Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about

Closed circuits return a certain amount of the ball mill's output back to the ball mill for further size reduction. Closed circuits are not unusual, and it's also not unusual that the ore will pass two or three times through the ball mill before proceeding further through the plant. Directly after the ball mill we be a classifier. Common classifiers include rake and spiral classifiers and also

Small variations in the feed size to ball mill circuits generally is not critical to the calculation of operating work index because they make a very small change in the 10 ÷ √F factor. Thus, a computer program can be developed to calculate operating work indices from on-line data with the feed size a constant and with the program designed to permit manually changing this value, as required
