is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop. The basic principle is to measure the height 'H' from the charge to the shell and the internal mill diameter 'Di'. By calculating the ratio 'H/Di' and using the graph below.

of elastic parameters on grinding and examined the relationship between them. The most widely known measure of grindability is Bond's work index, which is defined as the resistance of the material to grinding. The standard equation used by them for the ball mill work index (Bond work index) is as follows: Wi = 1.1 ×. 44.5.

In a ball mill of diameter 2000 mm, 100 mm dia steel balls are being used for grinding. Presently, for the material being ground, the mill is run at 15 rpm. At what speed will the mill have to be run if the 100 mm balls are replaced by 50 mm balls, all the other conditions remaining the same? Calculations: The critical speed of.
