Calculation of the power draw of dry multicompartment 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

Ball Size as Initial Charge Commercial ball sizes 10 – 150 mm Number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge For the initial chargin of a mill Coghill and DeVaney 1937 defined the ball size as a function of the top size of the feed ie d↓V 040 K√F
