### Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

### Milling formulas and definitions

The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters

### SIZE REDUCTION AND SIZE SEPARATION

The optimum size reduction in a ball mill depends o the following factors: Feed quantity: Too much feed will produce cushioning effect and too little feed will produce loss of efficiency of the mill. Speed of rotation of the cylinder: · At low speed the mass of balls will slide or roll over each other and only a negligible amount of size reduction will take place. · At high speeds, balls
