Introduction Vertical roller mills (VRM) have become the standard for grinding raw materials in the cement manufacturing process. However, despite the fact that more than 10 years has passed since ...
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
The choice between a vertical roller mill and a ball mill for cement grinding ultimately depends on the specific needs and constraints of the cement plant. VRMs offer significant energy savings, finer product control, and reduced maintenance costs, making them an attractive option for modern cement plants focused on efficiency and sustainability.
Ball mills and grinding tools Cement ball mills are typically two-chamber mills (Figure 2), where the first chamber has larger media with lifting liners installed, providing the coarse grinding stage, whereas, in the second chamber, medium and fine grinding is carried out with smaller media and classifying liners.
