Currently, 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 …

Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating.

sequence, grinding plants in the minerals industry are being designed for ever increasing throughput capacities. Grinding systems of the third generation also assure cost-effective processing and sparing use of re-sources. In this respect, the combination of POLYCOM® high-pressure grinding roll and ball mill represents tech-

grinding the same types of cement, namely ball mills coupled with high-pressure grinding rolls and a vertical roller mill. Over the years Buzzi has developed trials to understand if a certain amount of water could contribute towards optimising power consumption. The answer has been positive, in a range of 5kg H 2 O/t of cement.
