IOP Conference Series: Materials Science and Engineering
Portland cement, water can be neglected during clinker production due to lower quantity compared with other solid raw materials [4], but it starts to be counted in the concrete and mortar processing [5]. In other words, water utilization is only counted during the cement product life cycle but not in the manufacturing processes [6].

Optimization design of waste heat power generation systems for cement
In cement plants, the energy consumption mainly occurred in raw mills [6], preheater groups [7], grate clinker coolers [8] and rotary kilns [9]. The energy loss of the plants, which accounted for about 35–39% of the total energy input, is due to exhaust gas, cooler and radiation heat transfer from the kiln shell [8], [9].
