Ball Mill Loading - Wet Milling - Paul O. Abbe

The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...

As mentioned, cleanliness of the slip rings affects the inefficiency of the slip ring brushes. If you have a wet milling process, chances are slurry spills get into the slip area and can be the source of problems. If you can't possibly find another type of brush, you just have to lessen the amount of balls loaded in the ball mill cylinder.

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
