What Is Grinding Media? Grinding medium is a metallurgical term, the energy carrier in the mill to pulverize the material by its own impact and grinding force. The most commonly used grinding media are ball media and rod media. In some cases, irregular shapes such as circular truncated cones, cylindrical balls, and short round rods […]

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% ...
