Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness.

Sag Mill And A Closed Circuit Ball Mill. In contrast, mills closed by fine screens are limited to using only the most competent media. Media Type. The type of media used in the IsaMill ranges from effectively free media source including smelter slag and coarse SAG Mill product, to low cost locally available sands.

grinding circuit (crushing, single-stage ball mill). Thus, the Etotal of a SAG and ball mill circuit is: Etotal=1.10×E ( 5 ) Partitioning the Total Energy Between SAG and Ball Mills The Bond-based method applied by Barratt involves deducting a SAG mill specific energy consumption, ESAG, from the overall circuit specific energy consumption ...

SAG is an acronym for semi-autogenous 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%.[6][7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.[8]
