Journal of Mining and Metallurgy, 52 A (1) (2016) 11 25 ...savings compared to conventional ball milling. The HPGR and air classification circuit used 20 – 30 % less energy than the HGPR, screen, ball mill circuit. While VRM was estimated to use 10 – 30 % less energy (depending on the type of VRM) than a ball mill circuit for a similar degree of comminution.
Predicting HPGR performance and understanding rock ...The HPGR model, combined with powerful computers and larger sample masses for simulation, can be used as a procedure to size and select an industrial HPGR unit and to analyze the equipment behavior under various operating conditions and feed characteristics.
