INCREASING SAG MILL CAPACITY AT THE COPPER

a 2 x 8500HP dual pinion drive system. The plant was designed to process 1585 h mtpof SAG feed. From startup, the mill struggled to meet the required production rates. Over time, a major initiative that involved blasting and fragmentation, optimization of the SAG millIntegrated advanced process control with a sag mill,,SAG mill weight stability and preventing of over filling of the mill Reduction of undesirable critical impacts, trough the integration with the impactmeter SAG mill throughput optimizationSAG Mills Archives | Mineral Processing & Metallurgy,AG and SAG mills are now the primary unit operation for the majority of large grinding circuits, and form the basis for a variety of circuit configurations.

Optimizing your SAG Mill | Mining Surplus

As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end.USING LUMWANA MINING COMPANY AS A CASE STUDY,identified between FLS and LMC. The SAG mill strategy was developed with the following goals in mind: • SAG mill load stability • SAG mill throughput optimization • Reduced charge generated undesirable impacts (ball on liner strikes). These goals are attained through maintaining SAG mill load set points; SAG load is measuredOrway Mineral Consultants Canada Ltd. Mississauga, ON,,and ball mills, have almost become obsolete in the move to higher milling rates required to process lower metal grades.
