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 ...

In this paper, COMSIM, a new simulator which runs under Excel spreadsheet will be introduced which uses a Population Balance Model (PBM) to simulate ball mills. Plitt and Nageswararao models have been used to describe the performance of hydrocyclones, which by linking to the ball mill model allow for closed-circuit simulations.

When the test ball mill is run in open circuit the design feed rate is 27.42 tonnes/hour. Figure 4 compares the predicted size distributions from the open circuit ball mill with feed rates of 20.0, 27.62 and 35.0 tonnes/hour respectively. As might be expected, the larger the feed rate the coarser the grinding mill discharge product.

Simulation of open circuit clinker grinding Comments are; 705 a) the coarse particles were broken very fast. The size distribution of the material inside the mill becomes finer along the length going from the feed to the partition (grate) end of the first compartment.
Ball Mill Operation -Grinding Circuit Startup & Shutdown. 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 .
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.
