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.

Effect of ball and feed particle size distribution on the ...

2018-6-1  For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.

MILLING CONTROL OPTIMISATION - Mintek

2012-2-7  • Mill feed cuts were prevented, resulting in a stable mill loading. • No huge power dips occurred, since any sign of the mill overloading was detected and rectified timeously. • The standard deviation of the mill load, flotation feed flow and density was considerably less in MillStar mode, as can be seen in the table below.
