J is the ball filling fraction. ρ charge is the overall charge density calculated as follows: ρ charge = total coal mass + ball mass / J ∗ Mill volume. α is the angle of repose, which is estimated to be about 35°. Mill capacity increases linearly with increasing ball load for both ball sizes within the considered range.

20101113&ensp·&enspcement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials.

20041013&ensp·&enspCalculation 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.

20191015&ensp·&enspA ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill
