It takes on the form of a simulator that aims to predict the evolution of the grinding media load, the grinding energy available in the ball mill and the final product size distribution. The simulator was first validated in a pilot scale ball mill and then applied in an industrial case."

rate at each screen size is calculated from a torque-mill test as in the example that follows. Torque mill solids load during test: 11.25 kg (24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge. Mill speed: 35.2 rpm (65 percent of critical speed)

A campaign of Vertimill™ pilot tests was carried out at 's York pilot plant facility.The Vertimill™ was operated in direct circuit configuration closed with a high frequency screen ( Vibrating Screen) and with screw speed of 87 rpm.The mill motor gross power registered during the Vertimill™ pilot test was adjusted with Prony brake curve data to provide net power draw.

The pilot-scale mill consisted of a 41.6 cm diameter cylindrical steel shell that was fitted with eight 13.0 mm width and 6.0 mm height rectangular lifters ().The mill was fitted with two exchangeable discharge end-plates, allowing for either overflow or grate discharge operation ().The dry ore entered the mill through a variable speed conveyor belt at a fixed rate (W) of around 1 kg/min (0.06 ...

Reduce mill feed size; Reduce ball charge size; The reduction of the mill feed size could be reduced by modification of the tertiary crusher system by increasing the power draught and proper screen sizing. Detailed scale up experiments indicated that the ball charge size should be reduced due to the small contribution to the grinding efficiency.
