Ball mill Wikipedia
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paintsBall mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel ballsExamples (ten) of equilibrium ball charges for the torque mill (top sizes) Table 1 89 mm (35 in) 64 mm (25 in) 38 mm (15 in) 50/50 wt% 76/25 mm 50/50 wt% 51/25 mm 76 mm (30 in) 51 mm (20 in) 25 mm (10 in) 50/50 wt% 76/51 mm 30/70 wt% 64/32 mm analyzed, in duplicate The mill is loaded with the grinding media, solids and water The grinding time is estimated for a desired energy input, E Ball mill media optimization Metcom Tech1/3/1992 BALL WEAR MODEL Menacho and Concha (1985, 1986) have recently developed a phenome nological model of ball wear that predicts the size distribution of balls and the steel consumption in a mill knowing the rate and composition of the make up ball charge: (d4d~) d~3mk(d4d44)U(ddk) 3mk k=l M(d) ~ (16) (d2d~) ~ di:3mk(d4d4k) ~ dF 3mk k=l \k=l cSrS Optimization of the makeup ball charge in a grinding mill
