Jul 13 2016 Thus some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70 while power consumption can be cut by 20 to 30. Additional options for high-pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.
Aug 19 2019 High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills primarily because the grinding media in conventional mills needs to be replaced on a more regular basis. This makes HPGRs more flexible when it comes to meeting your campaign timings.
The technologys working principle is that two counter-rotating grinding rolls expose a column of material to high pressure which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by .
High pressure grinding roll - saving energy and providing results The HPGR truly is a unique comminution product. It weakens rock structure and exposes ore particles making it an attractive option for heap leach applications.
