A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh 45 m. Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting.
Live ChatCurrently, there is no standard recognized bench-scale laboratory test for sizing or modelling a high pressure grinding roll HPGR in hard rock mining. As a result, metallurgical studies are prohibitively expensive and not economical for early-stage projects. To be adopted as a standard industry test for the HPGR, a bench scale test must 1 use the same breakage mechanism as an HPGR, 2.

Cone crushers, rolls and hammer mills are examples of the equipment used. The cone crusher is a modified gyratory crusher with a shorter spindle that is not suspended, but supported in a bearing below the.

Live ChatGyratory Crusher The essential features of a gyratory crusher are a solid cone on a revolving shaft, placed within a hollow shell which may have vertical or conical sloping sides, as shown in Figure 1.16. Material is crushed when the crushing surfaces approach each other, and the crushed products fall through the discharging chute.
