A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...

The ball mill oversize feed factor (EF 4 BM) is always calculated with the ball mill work index. The optimal feed size for the EF 4 BM is always calculated using the rod mill work index. The Easag RM value in the circuit configuration is used to specify which work index to use for a particular size (RM above this size or BM below it). The RM ...

Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standard rod mill.
F.C. BOND BICO BALL MILL The F.C. Bond Ball Mill is a small universal laboratory mill used in calculating the grindability of all ores. GRINDABILITY IS THE NUMBER OF NET GRAMS OF SCREEN UNDERSIZE PRODUCED PER REVOLUTION. This Ball Mill can be used continuously or it can be used for any number of revolutions, according to the type of grind desired.

the mill builder can provide the gear designer with input power and output speed. The next step is the interface dimen-sions. Since the gear needs to turn the mill, it needs to have a bore larger than the mill outside diameter. The mill out-side diameter is a function of the grind-ing process selected. Autogenous mills
torque mill test is the mill energy input divided by the solids load. The energy specific cumulative grinding 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 ...
