Ball Mills an overview ScienceDirect Topics

Ball Mills. Ball mills have been used for the preparation of coal–oil and conventional coal–water slurry fuels, also in large sizes up to a capacity of 50 tonnes of coal per hour (Austin et al., 1984).

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.
