[email protected]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.
(grinding) industrial - grinding consists of rocks (same as ag grinding), and typically a 4 to 12% charge (up to 20% in some cases) balls are added to avoid build up of critical material and to
for a single size of make-up ball, the mass fractions in the mill within the size ranges are calculated from: (11) m k = d k u 4 − δ − d k l 4 − δ d max 4 − δ − d min 4 − δ where d k u and d k l represent the upper and lower boundaries of the ball size interval k, d max is the largest ball size in the mill, and d min is the smallest ball size in the mill which is still retained. δ is a …
