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%

An undersized bearing measures the same outside but is thicker on the inside. For instance, if a completed bearing measures 3 inches on the outside diameter and has a stock metal thickness of 0.20-inch, then its inside diameter will measure 2.40-inch. Add 0.10-inch of thickness to the inside to create an undersized bearing and you've still got
