Mill (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% A SAG mill ,The operation of AG/SAG mills is sensitive to mill filling, therefore developing grindcurves to relate mill fillingto performance indicatorssuch as throughput,power draw, and product size can assist in achieving.

Ball mill

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 shellcharge is a function of the bulk fraction of the SAG mill volume (Jb) occupied by balls; the ore retained in the mill is the result of the volumetric filling which depends on the ore size distribution (spe.

Modelling and Simulation of the Santa Rita Mine Milling ,SAG Mill Grinding Circuit Design

Simulation 4 included changes adopted in Simulation 3, along with (a) reducing the SAG mill ball diameter from 5" to 4", (b) reducing the ball mill ball diameter from 25" to 2" and (c) increasing the ball charge in the ball mills from 275% to 30% All these modifications aimed to increase the energy consumption in both SAG and two ball mills, which would thus be converted into a higher .With a higher density mill charge SAG mills have a higher installed power density for a given plant footprint relative to AC mills With the combination of finer grind and a lower installed power density (based on the lower density of the mill charge), a typical AG mill has a lower throughput, a lower power draw, and produces a finer grind.
