W is the work index measured in a laboratory ball mill (kilowatt-hours per metric or short ton) P 80 is the mill circuit product size in micrometers; F 80 is the mill circuit feed size in micrometers Rod mill A rotating drum causes friction and attrition between steel rods and ore particles

xG is the mill feed d80, not the circuit feed For SAG mill, the xG value has to be determined by scalping of the full size distribution The particles larger than the minimum pebble size (given by the pebble extraction grate opening) has to be excluded from the distribution to calculate the top ball size!

A ball mill is a type of grinder used to grind and 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

DOVE ® Ball Mills are size reduction machines, designed for grinding applications, where fine material is required Applicable for the grinding applications within the following branches of industries: – Mining – Construction – Waste Processing – Food Processing – Chemical – Pyrotechnics – Ceramics and etc

The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns

Optimum choice of the make-up ball sizes for maximum throughput in tumbling ball mills including the feed size, the product size, the mill diameter and the breakage parameters In all cases, binary mixtures of two ball sizes Mining Engineering (1958), pp 592-595

Mine-to-mill optimisation: effect of feed size on mill throughput (eg, smaller than 12mm) that will pass through the primary mills and onto the secondary ball mill circuits, alleviating a common bottleneck Modifying blasting practices to achieve a more suitable mill feed size – which varies according to the crushing/grinding circuit
