Review on vertical roller mill in cement industry & its

2021-1-6  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. Mill Gas Flow The three roles of the gas flow in the Vertical Roller Mill are
