These three types of grinding equipment have different length-diameter ratios, that is, different L/D ratios. L/D ratios of ball mills, rod mills and SAG mills. Besides, the diameter of the hollow shaft at both ends of the barrel of the SAG mill is large and the length is short. The diameter is large for its large feeding size.

Work speed defines the speed at which a grinding wheel passes over a workpiece or rotates around a center. High work speeds lower the heat retention and reduce the risk of thermal damage. Both high work speeds and reducing the diameter of the wheel result in increased grain depth of cut, performing like a softer grade wheel.

The horsepower of the grinding machine can play a role in determining the grade of the bond or the hardness of the wheel. When a machine has a higher horsepower available at the spindle, harder wheel grades are wiser. The harder wheel will hold form and retain the grains as long as possible under the stronger forces.

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can
