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% ...
The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform. The wet ball milling can not only grind agglomerate into fine particles, but ...
