We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or
Nov 10, 2020· The coefficient of grinding for the mill is 22-25 per cent of the internal volume. The calculation of the average balls diameter in each chamber showed that the following assortment of grinding balls should be used to maximize grinding: — In the first chamber: 90mm — 3 tons, 80mm — 2 tons, 70mm — 500kg, 60mm — 500kg.

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 The general operation of a grinding mill is to have the product impacted between the balls as
For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
