Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

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.

Critical Speed of Ball Mill . For a ball mill, it does not have a constant critical speed, because of the centrifugalization of the steel balls is different according to different resistance and friction between ball loads.But the ball speed of centrifugalization is constant. When the critical speed of the ball mill also has a constant value, such as the grinding medium fill rate, liner type ...
The critical speed can be understood as that speed after which the steel balls (which are responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding. ... and 2-4 hours for high-quality black powder. 6-Pound, Dual Drum Ball Mill (Skylighter #TL5005) Note: ...
