The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially. Interior of the drum uses the lifting plates. These plates inside the drum are responsible for picking the grinding material up to fall down again throughout the rotations. Repeated collisions between the steel balls and raw materials (ore

In ball milling, particle size reduction occurs by impact and attrition breakage. It is established in ball milling, the particle size distribution curve of the product is generally parallel to the feed size (Bond, 1961). In HPGR, size reduction is attributed to compression and interparticle abrasion breakage. Given the different force mechanisms used to reduce particle size in these two

For the feed sample sizes investigated, the three ball mix was more effective for the coarser feed due to the presence of the 50 mm balls whilst with a finer feed the binary mix gave the optimal amount of size class of interest. These results prove that a close control of feed and ball match is of paramount importance if one is to improve the efficiency of milling circuits.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser 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. A ball mill consists of a hollow cylindrical shell rotati
