Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter ( Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

The Ball Mill, B101, grinds the " ore until it is in the range of 160 microns. The ore leaving the ball mill is sent to six hydrocyclones that separate the larger particles from the smaller particles. The top stream leaving the cyclone is 75% of the feed into it. This top product is 160 microns or less.

mills can have correspondingly smaller sizes than usual. The material is dried in the ball mill. This system allows for the incorporation of several ball mills and permits separate primary grinding of different components. The defined size of the feed material allows for optimum grading of the ball charge.
