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 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
