Abstract. Current industry practice for HPGR assessment and sizing relies on conducting a series of tests using pilot-scale machines with roll diameters of 700 mm to 1000 mm. Substantial amounts of sample are required for such pilot test programs, typically 1 to 10 tonnes of the sample is needed depending on the level of study and complexity of 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
