The influence of mill speed and pulp density on the

and motor The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test The pulp volume of the pulp in the mill is then calculated using the mill discharge density (before dilution) obtained during the sampling.

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 @ Allis-Chalmers.
