SAG is an acronym for SemiAutogenous 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' () in diameter, powered by a 28 MW (38,000 HP) motor. Get Price
USING THE SMC TEST® TO PREDICT COMMINUTION CIRCUIT PERFORMANCE INTRODUCTION As the SMC Test ® produces the JK parameter values A and b as well as estimates the JK parameter ta and crusher model energy matrices, the SMC Test ® can be used to conduct AG/SAG mill and crusher circuit simulations through the use of JKSimMet. Independent
high pressure grinding roll drive Mill (grinding) Wikipedia. High pressure grinding rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed.

reduced wear can increase uptime and overall mill throughput. The nature of the HPGR mill design with its independent grinding rolls requires an innovative solution for the control of the rolls when driven by a VFD. This paper reviews available drive control methods to determine a solution that will promote low roll
BariteFluorsparZinc Ore Grinding. The ore for treatment is of such a nature that conventional grinding to —65 mesh using a ball mill classifier circuit results in excessive overgrinding of the barite. To avoid this condition a rod mill is used instead of a ball mill for reducing the feed for flotation.
