In a ball mill circuit the output can be defined as the production rate of fines of the circuit as for any output ball mill circuit output is a function of both its inputs and efficiencies there are two inputs to a ball mill circuit the ore fed to the circuit and the power delivered by the grinding mill
Ball mills can be used to further break down or refine a single material or you can place multiple materials into a ball mill jar to mix as you pulverize this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes ball mills basically function like a mortar and pestle but on a much larger scale

The feed of the ball mill contains grinding balls in order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible
With more than 100 years of experience in ball mill technology metsos ball mills are designed for long life and minimum maintenance they grind ores and other materials typically to 35 mesh or finer in a variety of applications both in open or closed circuits experience of manufacturing and installing over 8000 ball and pebble mills
Spreadsheetbased simulation of closed ball milling circuits
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 ie
