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 kW h/t and about 10 kW h/t when recycling of the material is HPGR consumes 3050% less specific energy as compared to a ball mill which indicates higher comminution efficiency for a HPGR.

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Most cement plants have restrictions with regards to their finish cement temperature, which should in a lot of cases not exceed 160 F (71 DEG C). Since in most cases the feed temperature of clinker is higher than 220 F (104 DEG C) and a ball mill creates additional heat, because of its inefficiency, additional cooling is required.
