The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill

mill. As such, primary ball mills should be designed with the rod mill work index, and singlestage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, Williams, 2006). On

a mill grindout (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grindout is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop. The basic principle is to measure the height ''H'' from the charge to the shell and the internal mill

A Bond Ball Mill Index Test (BBMWI) is a standard test for determining the Ball Mill Work Index of a sample of ore. The BBMWI is a measure of the resistance of the material to crushing and grinding. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding consitions. JKTech Pty Ltd 40 Isles Road, Indooroopilly, QLD 4068, AUSTRALIA

It has been recognized that the grindability of an ore in a ball mill is a function of both feed and mill parameters: Mill Throughput Capacity (Austin et al., 1984) Austin et al. concluded that a single expression for capacity is not adequate for all mills. Equations for mill sizes less than in diameter and greater than were proposed: t/h D < m t/h D > m
