Effect of High Pressure Grinding Rolls (HPGR) pre

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.

Why HPGRs are revolutionising mill circuits

2019-8-7  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.

High pressure grinding rolls (HPGR) - Metso Outotec

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
