Low-Temperature Electrochemical Cement Clinker Production

Low-temperature electrochemical cement clinker (e-clinker) production is a promising technology for reducing carbon dioxide (CO 2) emissions in the cement 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 Effect of High Pressure Grinding Rolls (HPGR) pre-grinding
