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.Web
The grinding process of Ball mill & Vertical Roller Mill differs fundamentally. The sufficiently high enough to cause fracture of individual particles in the bed & most of the particles on the bed are considerable, smaller than the bed thickness. On the other hand, in a Ball mill, the comminution takes place by impact & attrition.Web
Vertical Roller Mill Working Principle When the vertical mill works, the motor drives the grinding disc to rotate, and the grinding roller rotates around the grinding roller shaft driven by the disc. The material entering from the feeding port falls in the center of the grinding disc and moves towards its edge under the action of centrifugal force.Web
