Ball Mill Motor Power Draw Sizing And Design Formula

Ball Mill Motor Power Draw Sizing And Design Formula

The following equation is used to determine the power that wet grinding overflow ball mills should draw for mills larger than 33 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 rod and ball mills by ca rowland and dm kjos allischalmers

Modeling Of Power Consumption Of Ball Mill

Modeling Of Power Consumption Of Ball Mill

The proposed model for determining the power consumption of a ball mill allows an assessment of the efficiency of electric energy consumption and electric mills identify qualitative indicators of

Charge Behaviour And Power Consumption In Ball Mills

Charge Behaviour And Power Consumption In Ball Mills

The combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level this demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in dem modelling
