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 ...

The "functional performance equation for ball milling" was first presented in 1988. It has now been used successfully in a substantial number of mineralprocessing plants. This powerful, yet simple, tool provides a new level of understanding of closed circuit grinding. It shows how grinding circuit efficiency is really comprised of two distinct efficiencies. It demonstrates how circuit ...

Typically, such work involves cleaning the ball mill, checking the liner wear (replacing it if necessary), noting the wear and tear on gear teeth and checking for any cracks that might be developing. All in all, the process should be relatively quick and uncomplicated though thoroughness is always essential. 2. Essential Repair Work.
