In order to compare this power with the cutting power calculated based on the formula that contains the forces and moments one have to calculate the instantaneous power during milling. Then, is possible to calculate the average power during a revolution of the tool (considering the same value, while the milling

Get Price2001-8-1 Typical power consumption for a 5-m diameter by 7-m-long ball mill is between 2.5 and 3.5 MW. The actual proportion of this energy usefully used in size reduction is thought to be very low, perhaps in the range of 1–5%. Significant financial and environmental benefits can be obtained by improving this efficiency even slightly.

Get Price2015-10-19 The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.
