Milling Circuit Optimization Study For Kroondal No 1

the kroondal plant consists of two primary ball mills converted from rod mills, which are running in parallel, and a secondary ball mill. the primary mills are lined with composite rubber liners while the secondary mill is lined with a rubber liner. figure shows the primary milling circuit, and figurethe secondary milling circuit at waterval concentrator had undergone a circuit change with the commissioning of the isamill, a horizontally stirred mill, in parallel with the secondary ball mill. the operation treats the pgm bearing ore type and produces a final concentrate enriched with pgms.ore per day in six overflow ball mills. the concentrate is transported to a smelter a few miles away. the crushed ore from primary and secondary ores is conveyed into bins. the ore from the bins is fed into the ball mill using a conveyor belt. the ball mill grinding circuit is illustrated in figure solids 78.9 circulating load 474% advance

Shedding Light On Fisrt Hand Crushing B

the ball mill is a 6.10 inside shell diameter 8.53 egl ball mill equipped with a 5,700 kwmotor. the ball mill operates in overflow configuration, discharging slurry over a trommel screen protecting the pumps from steel media. trommel undersize discharges into the common cyclone feed hopper. grinding balls are charged secondary ball mill circuit. mills and onto the secondary ball mill circuits, alleviating a common bottleneck. modifying blasting practices to achieve a more suitable mill feed size which varies according to the crushinggrinding circuit can achieve up to a 30% increase in throughput.finally, a matrix model transformation of a binary ore was developed for a basic closed ball mill-hydrocyclone circuit. the model described satisfactorily the grinding behaviour of the chromite and non-chromite separately. this model is useful for showing effects of the milling of a binary ore on the ball mill circuit

feb 01, 2011 the plant is set up in a mill float mill float circuit with primary and secondary milling stages prior to primary and secondary rougher flotation respectively. the tests for this project were carried out on the secondary ball mill. the ball mill has a diameter of 7.32 and length of 9.45 and has an overflow configuration.secondary milling to between and 72% passing with natural fines grits. comminution circuit description the plant consists of two primary ball mills converted from rod mills, which are running in parallel, and a secondary ball mill. figure shows the primary milling circuit, and figure the secondary milling8.3.2.2 ball mills. the ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 11.5 times the shell diameter the feed can be dry, with less than moisture to minimize ball coating, or slurry containing 2040% water by weight.

also, the mill load varied in the range of 125 to 165 tons. these disturbances propagated throughout the milling circuit and even to the flotation circuit. the millstar power optimiser gave the following benefits: mill feed cuts were prevented, resulting in a stable mill loading.
