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.
on. August 10, 2022. By. admin. Grinding might be an individual step in the cement production line but it is a crucial one, given the energy consumption and impact on the quality of output that it gives. ICR explores how grinding methods have evolved with the help of technology and with the use of modern-age grinding aids.
Because raw coal is still used in cement manufacturing, equipment that can grind coal onsite is necessary for most cement plants. As with the actual milling of cement, manufacturing equipment used to break down the coal requires mechanisms with airlock capabilities. These must be able to handle capacities from 10-100 tons hourly.
