Ball Mill Design/Power Calculation

The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution The following shows how the size or select the matching mill required to draw this powerCalculate and Select Ball Mill Ball Size for Optimum Grinding,In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often, the ball used in ball mills is oversize “just in case”Velocity Calculation In Ball Mills | Crusher Mills, Cone ,Tumbling Steel Ball Mills and Ceramic increase efficiency of the mill one would have to tune the rotation velocity so ball mill efficiency calculations derive the equation of critical speed of ball mill
