Grinding is carried out either in a ball mill or a vertical spindle mill in which rollers grind the material in a pan (Fig. 4). The latter is now usually selected for grinding raw materials in a new plant (unless they are exceptionally abras ive) as it uses significantly less energy for a given fineness than a Fig. 4.

In fact, grinding is often considered a subset of cutting, and vice versa, since each grain of abrasive on a grinding wheel acts like a microscopic, sharp cutting edge that shears a tiny chip from a part surface. In general, precision metal grinding processes are used to remove small amounts of material in order to achieve a particular finish ...
