Ball charge ball mill 3dnl Ball mill charge bees measurably swollen only when there is a buildup of large unground material in the ball mill or when the density of the pulp in a wet mill is extremely high Although these conditions are seldom encountered it is remended that ball mills be ground out prior to shutdown for measurement of the .

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, ceramics, etc., as well as for ore dressing of ferrous and non-ferrous metals. The ball mill can grind ores and other materials, wet or dry.

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.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge; Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space; Add to this another 10%-15% above the ball charge for total of 23%
