When cassiterite polymetallic sulfide ore is being ground in the ball mill, the contradiction between over grinding of cassiterite and under grinding of sulfide ore is inevitable due to their mechanical property differences. In this paper, a selective grinding characterization method is proposed to optimize the grinding of cassiterite polymetallic sulfide ore based on the respective selective ...

A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energysize reduction function, which calculates the particle breakage index, t 10, according to the sizespecific energy, and then calculates the full product size distribution using the t 10 t n relationships and the masssize balance approach.

A grinding system in which the crushed product is not classified or returned to the ball mill is called an opencircuit grinding system. Therefore, the circulating load is a crucial parameter to evaluate the running state of the grinding mill. For the secondary ball mill, a common grindingclassification system is shown in Figure 2.

In the 1950s and 1960s ball mills dominated primary grinding, however they were supplanted in the 1970s by AG and SAG mill which also replaced two stages of crushing. Nowadays ball mills still dominate secondary grinding applications, but are increasingly in competition with closed circuit AG/SAG mill circuits and stirred mills .
