High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

A ball mill is a cylindrical device that grinds or blends materials by impact and attrition. It can be used for various purposes, such as mineral dressing, paints, ceramics, pyrotechnics, and selective laser sintering. The grinding media are the balls, which may be made of steel, stainless steel, ceramic, or rubber. The grinding works on the principle of critical speed.

It seems certain, however, that the ballmill will crush to 200 mesh a considerably greater tonnage when the proper classification is provided. Since in previous tests the mill has crushed 7½ T. per hr. from ¼ in. to 200 mesh, it seems possible that it will crush at least 8 T. per hr. from 48 to 200 mesh.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize 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% ...
