Mill grind out In order to measure the ball load in the mill, the feed to the mill was stopped and it was ground out to a ball charge only. As a result of slurry pooling in the mill, the surface of the charge could unfortunately not be inspected, and the 9.7% ball level was measured relative to the slurry, 398mm below it.

SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

A ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. The materials are ground by moving the container. Because the structure of ball mills is simple and it is easy to operate, and so they are widely used.

to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position.

In this investigation, grinding efficiencies of a ball mill were studied using combined ball charge regime (i.e., 60 and 80 mm) and mono-sized balls (i.e., 80 mm). Several criteria were utilized including grinding index (GI), P80 and selection function (SF) to evaluate the impact of the ball charge regime on grinding.
