Ball Mill Loading (dry milling) When charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product. Charging a Dry Mill
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
