Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to 200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turn-key ...

For example, 5mm media are used in many attrition mill applications, whereas 10-15 mm may be a good start for a lab ball mill. For small-media mills, media sizes are typically smaller than 2 mm. Another important criterion in selecting media size is the gap size between stirring arms and mill walls.

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.

The mill jars are rotated with the aid of a jar rolling mill, which has two rollers to support and rotate the jars at the proper speed. The milling jar is half filled with grinding media or balls from ” to 1” and as the mill rotates the solids are trapped between the ball and are milled down to as little as 1 micron by the cascading and ...
