The effect of grate design on the behaviour of grate ...

1986-9-1  A model for the effect of flowrate and viscosity of slurry on the hold-up of slurry in a grate-discharge grinding mill has been developed. Given detailed specifications of the grate design (such as the area in the grate within which the holes are situated, the number of holes per m 2 and the hole size) and the flowrate and viscosity of the slurry flowing through the mill, the model provides ...

Improved Relationships for Discharge in SAG/AG Mills

2019-10-9  The aim of this thesis is to improve on the current understanding of discharge in the SAG/AG model. It focuses on the present limitations of the JK AG/SAG model in predicting accurate grate and pebble port discharge. The thesis objective was to design a pilot scale test that can accurately measure and explore discharge mechanisms.

Mill power draw models - SAGMILLING.COM

2020-3-22  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.
