Comminution Circuit Design and Simulation for the

The application of High Pressure Grinding Roll (HPGR) in comminution circuits is well established in processing cement, diamonds and iron ore. Recently, the application of HPGR has been extended to high-tonnage precious and base metals operations with hard ore. This is due to the HPGR: being more energy-efficient than grinding mills, not

Nov 19, 2018 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.

The pressure profile across the roll displays a tapering off of pressure toward the roll edges, leading to impaired comminution performance. The ‘edge’ proportion is a function of the operating gap (edge = gap x ~1.2), which is in turn a function of the roll diameter (gap = 2–2.5% of diameter), so a high aspect ratio design has a greater edge
