· Ball Mill is the equipment to be used for size reduction. It is a kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls. The size reduction is actually to make the too large to be used solid materials usable. It leads to an ...

calculated via manufacture`s ball charge program. At the time of this research, mill ball charged, feed rate, and average moisture were 7 tons (ball size was 100 mm) per week, 720 t/h and 5%, respectively. Then, ball abrasion rate was calculated by Equations 4, 5 and 6. Total mill feed per week = 720*24*7*= 114912 tons (4) Total ball charge per week = 7*106 g (5) Ball abrasion rate = (7 ...

· Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows: Example Calculation. A motor with ...
If M is the total mass of the charge within a mill and dM/dt is the rate at which the balls are consumed, the time constant of a mill is θ = ( Eqn. 1) The ball charge used was 22 tones. The mass of material milled is T hence the ball consumption in kilograms per ton milled becomes: = ( Eqn. 2) A tonnage constant' for the mill, jm, can be ...
by mill operating parameters. It is hoped that this work can be used as a precursor to the development of a model that can predict liberation given the various ranges of operating parameters. Mill speed, mill charge, ball size, and wet grinding are the parameters which have been selected for the present study. It is hoped that the analysis of the
