Jan 01, 2005 Publisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG. read more

Ball mill grinding machine is a kind of horizontal drum-type grinding mill with external gear and double bins. Materials goes evenly through quill shaft in feeding device into the first bin, which has ladder lining or ripple lining with steel balls in different specifications.Steel balls are taken to a certain height by centrifugal force from drum rotation and then fall. read more
maximize this rate. The mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the material’s grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent read more
