How energy efficient is HPGR? - ceecthefuture.org

2018-2-20  HPGR power savings relative to SAG-ball mill circuits and crusher-ball mill circuits exist but cannot be reported due to client confidentiality limitations. This compilation of examples from the literature is therefore far from complete, but is encouraging nonetheless. HPGR machines have been installed for

Effect of ball load and size distribution on grinding and ...

2015-12-1  An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag ® ball mill on grinding and classification performance of a hybrid high pressure grinding roll (HPGR)/multi-compartment ball mill cement grinding circuit. Mass balance of the circuit was done by JKSimMet Steady State ...

Effect of High Pressure Grinding Rolls (HPGR) pre-grinding ...

2016-6-1  High pressure grinding rolls (roller presses) are used in both cement raw materials (limestone, clay, shale etc.) and cement grinding stages. The energy consumption is 2.5–3.5 kW h/t and about 10 kW h/t when recycling of the material is used.A HPGR consumes 30–50% less specific energy as compared to a ball mill which indicates higher comminution efficiency for a HPGR.
