Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Mar 08, 2013calculation of ball mill grinding efficiency. dear experts . please tell me how to calculate the grinding efficiency of a closed ckt open ckt ball mill. in literatures it is written that the grinding efficiency of ball mill is very less [less than 10%]. please expalin in a n excel sheet to calcualte the same. thanks. sidhant. reply

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.

Adding grinding aid to the mill can increase the production capacity by about 10%. Generally, triethanolamine is used, and the blending amount accounts for 0.04%~0.1% of the milled material. (4) Calculation of ball mill production capacity All of the above factors affect the production capacity of the mill.

Popular Answers ( 2) Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be 21 24 % of the empty mill. Now, in order to get an efficient milling action, 80 110 % of the pores in the ball bed must be filled with the actual particles to be ground. Then, by doing simple calculation, the particles occupy 11.2 17.6 of the mill volume.
