Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the sizeThese ball mills are relatively small, bearing mounted on a steel frame All ball mills are sold with motor, gears, steel liners and optional grinding media charge/load Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long, offerBall Mills Mineral Processing & MetallurgySome experimentation is inevitable in determining the exact amounts of material charge to use While the media charge should always be 50%, material charge will vary from 25% to 40% or more in some cases such as when grinding 100% homemade airfloat charcoal The best way to tell if your mill is properly charge is to listen to it afterBall Mill Design freeshell
