Reducing energy consumption of a raw mill in cement industry
Several grinding methods are available in cement industry depending upon the material to be ground. In cement production process, about 26% of the total electrical power is used in grinding the raw materials. During grinding process, the energy obtained from the rotary burner is consumed. In this study, the first and second law analysis of a The cement factory where the measurements were made was located in Romania’s center-north and had a final section with two cement mills. Cement grinding was performed inside the cement mill workshop. This manufacturing phase’s product was cement—a powdery, finely ground material in closed-loop tubular ball mills .

Distribution of dust emissions at bag filters in the cement mill section no.1 (mill filterpoint A and separator filter-point B, Figure 1) of the analyzed cement plant.The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.Energy-Efficient Technologies in Cement Grinding IntechOpen

Review on vertical roller mill in cement industry & its
Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement. Cement companies also want to produce more and more PPC grade.The cement industry is highly energy-intensive, consuming approximately 7% of global industrial energy consumption each year. Improving production technology is a good strategy to reduce the energy needs of a cement plant. The market offers a wide variety of alternative solutions; besides, the literature already provides reviews of Technological Energy Efficiency Improvements in Cement Industries
