The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

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, semiautogenous grinding (SAG) ballmill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.

Figure shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. This is a normal setup as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose primary function is ...

The circulating load ratio is an excellent subject for study of classification system performance because it has long been recognized as such an important factor in ball milling efficiency. Results from the classical work of Davis (1925) are shown in Figure 2. Note that an increase in circulating load ratio from 150 to 500 percent yielded an ...

HPGRBall mill circuits have the potential to reduce the Mining Industry's CO 2 emissions by megatonnes/year when compared to AG/SAG/Ball mill circuits. This saving climbs to megatonnes/year if HPGRs are also used instead of ball mills. Despite this huge potential saving, uptake of HPGR technology has been relatively slow.
