calculation 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

mill test, the calculation method of the mill energy specific cumulative grinding rates is shown by the following example. Using plant data, the value of E is the specific energy input to the solid material as it passes through the plant mill (the mill power draw divided by the mill solids throughput rate), and assumes plug

Due to limitation of the mill’s rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5-8 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% 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”.
