The origins of the RoM mill also drove the philosophy of single stage grinding to final product, nominally 75% to 80% passing 751lm. Much of the early AG/SAG model development work at the JKMRC was based on Australian and North American style mills and operations and hence had not been validated under typical South African RoM mill conditions.
This included a simple flow sheet with a 60 x 89 gyratory crusher (the largest proven crusher at the time), 38 ft. diameter SAG mill, and 160 m 3 flotation tank cells. The conical stockpile design included a single reclaim tunnel, providing sufficient capacity for 18hour storage of product.

Principle of SAG Mill operation SAG mill. SAG is an acronym for semiautogenous grinding. SAG mills are autogenous mills that also 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' () in diameter, powered by a 28 MW (38,000 HP ...
The singlestage closed ROM ore milling circuit considered in this study is shown in Fig. 2 and constitute a SAG mill with an enddischarge grate, a sump and a hydrocyclone. The mill receives four streams as inputs: mined ore, water to assist with material transport, steel balls to assist with ore breakage, and under ow from the hydrocyclone.
