### Ball Mill - Wikipedia

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 shell may be either,amit 135: lesson 6 grinding circuit – mining mill operator,semi-autogenous grinding (sag) mill. wet or dry; higher capacity than a-g mill grinding; primary, coarse grinding (up to 400 mm feed size) grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) high capacity (short retention time) less sensitive to feed composition (critical size material) semi-autogenous mill
