The resultant figure will then relate to the motor output power capacity usually referred to as the installed power. Ball mill dimensions and operating conditions. The final step is to choose a ball mill diameter, length and speed that will draw the installed power when loaded with the mill's maximum allowable ball load.

Where N (kW) represented the power of ball mill pinion shaft; K ωb (kW/t) was the power for per ton ball medium; G (t) represented the weight of media loaded in the ball mill. Usually, the power of the ball mill pinion shaft was directly proportional to the motor power of the ball mill, and the correlation coefficient was

The milling of the pyrolysed carbon was carried out in a conventional planetary ball mill Fritsch Pulverisette 7. The ball milling times used were 10, 20, 45 and 90 min without interruption into an agate cup sealed in air. During the milling, three agate balls were used: the weight of agate balls to carbon material ratio was about 14:1.

I'm interested to know when sizing a new ball mill, as to why recirculating load has no effect on the power calculation, although it will have effect on volumetric capacity naturally. For instance a mill of 300tph with a 300% recirculating load would have 1200 tph going through effectively, but if

Typical power consumption for a 5m diameter by 7mlong ball mill is between and MW. The actual proportion of this energy usefully used in size reduction is thought to be very low, perhaps in the range of 15%. Significant financial and environmental benefits can be obtained by improving this efficiency even slightly.
