ratio balls in vertical ball mill

One comment that I did not see here is the potential for differential grinding, especiallyin vertical mills, but also inball mills. That is when inter-grinding different materials, the softer materials tend to be ground finer. In air sweptvertical mills, this can leave a higher quantity of the harder to grind material in themill.

Ball Mill - an overview | ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially5–10 cm diameterbut 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.
