Optimization of the make-up ball charge in a grinding

1992-3-1  The overall effect of a mixture of balls in the mill may be taken as the linear weighted sum (Austin et al., 1984e): L S, = Z mtSjj ( 14 ) /=1 L L Bi,= ( m,Sj.,Bo,l) / Z rnlSj.r (15) l=1 r=l The ball charge in the mill is split into L ball classes with diameters in a 4x/2 ratio, and mt is the relative mass frequency function of balls of size dr.

Ball Mill Loading - Dry Milling - Paul O. Abbe

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

Ball Mill - an overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
