black soil material may accumulate on the bench and create a hazard. Once into the hard rock below the soil cover the slope angles will be adjusted to a 40-45° angle and will be consistent with a typical pit design. A detailed rock mechanics analysis of the project area was undertaken in 1979 for a preliminary feasibility study.

Ball Mill Critical Speed
Ball Mill Critical Speed. A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula.

Ball Mill
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.
