HPGR High Pressure Grinding Rolls

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

Why HPGRs are revolutionising mill circuits

High Pressure Grinding Rolls are generally thought to only be effective in controlled “dry” grinding applications, however (depending on the material saturation level) they can readily process minerals well above 10% moisture. This gives HPGR’s the flexibility to fit into a wide array of applications with both wet and dry classification.

Effect of High Pressure Grinding Rolls (HPGR) pre

01/06/2016· 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. Four circuit
