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.
Summary: This paper presents the effect of operational parameters on the performance of a closed circuit HPGR. For this study, six surveys in a cement grinding circuit operating in Turkey were performed. The relationships among operational parameters like gap, pressure and capacity and the effect of these parameters on the performance were investigated.
