The consumption of the energy in the cement plant is mainly due to raw mill, cooler, pre-heater and rotary kiln [14]. The total energy loss of the plant is generally accounted for about 35-39% of the total energy input [15]. This energy loss is due to the loss from the exhaust gas, cooler and the radiation heat transfer from the kiln cell.
Additionally, the ball mills and the vertical raw mill reached 4 – 5% improvement on specific energy consumption. At the kiln, the savings of specific thermal energy consumption totalled 3.4%. All five assets are maintained and currently used in closed-loop mode without human intervention, while the process is in a steady state.

Cement Plant Cuts Coal & Energy Usage By Up To 2%. Decrease coal and energy consumption – and related greenhouse gas emissions. Cement is one of the most widely used products in the world. But demand is especially unrelenting in China, which leads the world in cement production. Cement is a critical ingredient for infrastructure and housing ...
The consumption of energy by the cement grinding operation amounts to one third of the total electrical energy used for the production of cement. The optimization of this process would yield substantial benefits in terms of energy savings and capacity increase. Optimization of the Cement Ball Mill Operation
use and now account for over 90 percent of cement consumption worldwide (4.1 billion tons in 2016). Cement accounts for at least 5 percent of anthropogenic emissions of greenhouse gases, and, according to some estimates, this share may be even higher. At the same time, energy-related expenses in the cement sector, mostly
The Energy Use Plant Ranking (bar chart) helps cement plants compare their own energy use to that of other plants in the industry.
