A ball mill is a type of grinder used to grind or 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.

Therefore, changes in circulating load on a single stage mill may affect the size of the slurry pool and consequently the power draw. Load indication is also very important for high ball charge SAG mills or Run of Mine (ROM) ball mills as changes in power draw resulting from changes in load may be insignificant.

rod mills 1/1800 ball mills, grate discharge 1/1200 ball mills, overflow type 1/1470 pebble mills 1/1200. W for rod and ball mills shall be taken as the weight of the rod or ball charge, the weight of the pulp is to be ignored. For pebble mills therefore W is to be calculated on the basis of the bulk weight of the pebbles.

How a Grate Discharge Ball Mill Works. Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.

With a batch mill, as previously suggested, the centre of gravity of the ball charge and powder charge sensibly coincide and so the density correction (1 + σ/q) previously deduced is applicable. In the grate mill the powder surface probably slopes from the inlet end of the mill to the discharge end in the manner indicated in Figs. and ...
