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 power is ,...
Example Calculation A motor with around 1400 Horse Power is calculated needed for the designed taskNow we much select a Ball Mill that will draw this power The ball mill motor power ....
If you size a ball mill based on Nordberg you use the hardness to derive the needed power to reduce to a target size at a particular throughput From that power draw you calculate a shell size from 4 parameters diameter, effective length, wet or dry? loaded and of critical speed...
Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous So direct measurement must be taken for calculation of mill load...
