Why HPGRs are revolutionising mill circuits

07/08/2019  Through the reduction of material and electrical waste, High Pressure Grinding Rolls are reducing the ecological impact of grinding. Indirect grinding reduces wear and tear In traditional cone crushing, and especially with hard and abrasive ores, the size reduction is achieved by direct contact between the ore and the liners resulting in significant wear and thus higher operational costs.

HPGR High Pressure Grinding Rolls

19/11/2018  Primary grinding in the high-pressure grinding roll increases the capacity of an existing dry ball mill operation. Even greater increases in capacity can be achieved if the Polycom is operated in hybrid mode. Hybrid grinding means that a part of the separator tailings (which are recirculated to the ball mill) is diverted and fed to the Polycom together with the fresh feed. Thus, some of the ...
