An industrial ball mill operating in closed-circuit with hydrocyclones was studied by five sampling surveys. The aim of the present study was to optimise operating parameters (i.e. charge volume, make-up ball size regime, slurry mean residence time, number of hydrocyclones in operation and hydrocyclone's feed solids content (Sf)) with respect to …

The first-order rates are commonly observed in batch grinding (Austin et al., 1984) and are the basis of modeling breakage in tumbling mills.In the case of particles contained in coarser size ranges, deviations from linearity are identified in Fig. 1, as have been observed by other investigators (Austin et al., 1982).This behavior, in which …
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
