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.

Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):Modifiion of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modifiion of the ball charge in order to improve the mill efficiency:
The charging of the ball mill milling media has a direct impact on grinding efficiency (1) If it is too much the grinding media will be overlapped with each other thus the crushing capacity of each steel ball cannot be fully utilized and the kinetic energy consumption will be increased.
Grinding media Ball is one of the essential parts of ball mill. The quality of grinding media ball affects not only the productivity of the ball mill, but also the consumption of ball, and then affects the cost of grinding medium. The pursuit of high hardness and low single consumption is not right.
Steel balls have a SG of 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 determined, however generally the range is from 20% to 50% of the mill volume, or to the center line.
