BALL CHARGE Selection is dependent upon the length of time for the dispersion, the maximum permissible temperature, the range of batch sizes to be produced and the end product quality. Above chart shows weights and volumes for a ball charge of 50 total mill volume.
ball charge is close to 95 kg 209 lb, occupying 34 percent of the mill volume. Balls are used that represent a fully graded charge based on constant wear rate in a continuously operating mill. Slurry volume occupies the 40 percent voids volume in the 34 percent ball charge. The drive shaft is torque-metered and records once per second.
The efficiency of a ball mill depends on the number of contact points between the balls There is a limit of ball diameter below which centrifuging of mill charge occurs this limit can only be overcome by a change in the manner of ball movement In sandmills, the grinding charge is driven by an impeller.

Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls.
Crushed ore is fed to the ball mill through the inlet a scoop small screw conveyor ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33 with balls range 30-45. Pulp crushed ore and water fills another 15 of the drums volume so that the total volume of the drum is 50 charged.
