Ball Mills - an overview ScienceDirect Topics

8.3.2.2 Ball mills. 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.

Oct 01, 1993  For a low investment, the Sala-Agitated-Mill (SAM) facilitates an energy saving of 25% to 50% in the area of fine grinding compared to that of the conventional ball mill systems, since the external sizing unit can be dispensed with because of the internal sizing effect of the SAM. This clearly simplifies the present grinding system.
