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 axiOptimum mechanical-alloying parameters were found to be ball-to-powder weight-ratio (BPR) of about 5, ball milling speed of about 178 rotation per minute Effect of ball-milling process parameters on mechanical
