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.
Jyoti Ceramic Industries Pvt. Ltd. L = Internal length of the mill in cms. after lining. To calculate grinding media charge for continuous type ball mill, M = 0.000676 x D2 x L Example - To calculate grinding media charge for a 180 cm dia x 180 cm long batch type ball mill with Duralox 50 mm thick bricks.
The optimal ball diameter in a mill 333 The grinding efficiency of the narrow particle size fractions with ball charge of various diameters has been observed through the constant of milling rate k in the equation of the grinding kinetics law for the first order grinding R=R 0
To calculate grinding media charge for continuous type ball mill, M = 0.000676 x D2 x L Example - To calculate grinding media charge for a 180 cm dia x 180 cm long batch type ball mill with Duralox 50 mm thick bricks. Formula to be used is M = 0.000929 x D2 x L D = 180 - 10 = 170 cms L = 180 - 10 = 170 cms Therefore M = 0.000929 x (170)2 x 170

The motion of an individual ball in the charge is complicated in practice and it is not possible to calculate the path taken by a particular particle during station of the charge. However the general pattern of the motion of the media can be simulated by discrete element methods which .
Ball Mill Media Charge Calculation. The ball mill is a tumbling mill that uses steel balls as the grinding mediahe length of the cylindrical shell is usually 11times the shell diameter Figure 8e feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
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". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
If too much product then the solid may buffer the impact too much. As with most of the independent variable in ball milling it is best to do some empirical testing and then adjust your parameters. The starting point for ball mill media and solids charging generally starts as follows: 50% media charge
The motion of an individual ball in the charge is complicated in practice and it is not possible to calculate the path taken by a particular particle during station of the charge. However the general pattern of the motion of the media can be simulated by discrete element methods which .
