Ball Mill Circulating Load - Mineral Processing &

Calculating a grinding circuit's circulating loads based on Screen Analysis of its slurries. Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. Pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or

Mill power draw models - SAGMILLING.COM

The design of mill liners and SAG mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput. All models generally assume that a mill is fitted with "efficient" liners and that the grate design neither limits passage of pebbles (and pulp) nor permits re-circulation of pulp back into the mill.

Optimizing your SAG mill operation -

Single stage AG/SAG mills have to handle large amounts of slurry as they are generally in closed circuit with classifiers whose circulating loads reach as high as 400-500%. The geometry of radial and curved pulp lifters is such that the slurry, once passed through the grate into the pulp lifter, will always be in contact with the grate until it is completely discharged, which makes the 'flow
