Online servicesFor 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.

Oleg D. Neikov in Handbook of Non-Ferrous Metal Powders 2009 Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems in batch and continuous operations and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore collision force direction and kinetic energy between two or more elements vary .
Ball Mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced.

Jan 14 2019 Over 10 years the magnetic metal liner has been used in more than 300 full-scale ball mills at over 100 mine sites in China. For example one set of the magnetic metal liner was installed in a 3.2m D x 4.5 m L secondary ball mill 60mm ball charge at Waitoushan concentrator of Benxi Iron and Steel Corp. in 1992.
One of the few things I had to buy for this project aside from the casters was the steel balls. I found these online. They were quite inexpensive. I went with 58 inch diameter balls which seem to work well in a mill this size. I have been powering the ball mill with my bench variable power supply so I could fine tune the rotation speed.
