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.
Apr 01, 2014 The effects of slurry pooling on ball milling have been investigated. Product fineness was found not to be a function of slurry pool volume. High ball filling J and slurry filling 1.0 ≤ U 1.3 led to high production of fines. From a batch milling perspective, slurry pool is undesirable for effective grinding.
