### Ball Mill Operation -Grinding Circuit StartupShutdown

Ball Mill and Grinding Circuit Preparation for Start-UP The following items must be checked before the equipment in the Grinding Circuit is started. Check the ore slot feeder for obstruction or hang—ups. Check the ball mill belt feeder for undue buildup of material. Check oil level in ball mill lube oil tanks. Also, check grease level in the mill ring gear spray lube drum. Ensure that the

get price### Simulation and optimization of a two-stage ball mill

The breakage parameters obtained from wet grinding tests were scaled-up and then applied to simulate an industrial two-stage ball milling circuit. The simulation reproduced the size distributions of all streams, and the mill production rate with great accuracy. The simulation revealed that the mill operation was far below the optimum.
