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

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 …

application of hpgr mills

In applications where the HPGR is followed by ball milling, the induced micro fractures generally result in a reduction of the Bond Work Index. For most ores this reduction ranges between 10-25%. Obviously this allows for grinding at either an increased throughput rate, at a reduced power input, or with a reduced number of mills.
