• ##### Ball mill

A ball mill is a type of grinder used to grind or blend 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 rotating about its axis. The axis of the ...

· Where a p is the axial DOC and f is the feed per tooth, or chip load. The number of teeth engaged with a workpiece (Z c) depends on the number of teeth in the cutter (Z) and the engagement angle (α). The formula for calculating Z c is: Z c = Z × α ÷ 360° (4) The engagement angle depends on the radial WOC (W). If the radial WOC equals the milling cutter diameter (D), the engagement angle ...
