  • 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. Ball mills are employed in either primary or secondary grinding applications.
