Grinding is the first step of mechanical material removal. Proper grinding removes damaged or deformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in .
The size of the balls used for grinding depends on the size of the material entering the mill; they should be just large enough to break the biggest lump of ore likely to be encountered. Balls of 5-in. diameter are the largest in common use, but they are only suitable for coarse feeds of 1-in. size or over.
