The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight.

To get rid of pulp and rocks in the charge a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grind-out is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop.

High density alumina (ceramic) balls have a SG of 3.2 and have an average weight/volume of 17.5 pounds per gallon. Steel balls have a SG of 7.7 and have an average weight/volume of 40 pounds/gallon. Higher density grinding media generally results in faster grinding in a ball mill. An optimum grinding charge for a ball mill may be experimentally

Mill Steel Charge Volume Calculation . We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media while the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill

HORIZONTAL/ TUBE / BALL MILL. A ball mill is a type of grinder used to grind and blend materials for use in various types of industries. A ball mill works on the principle of impact 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 its axis.
