The coal, which will be used to fire the cement rotary kiln, will be ground to a product fineness of 15% residue 90µm. The mill with an installed power of 570kW is designed for a finished product rate of 40 t/h. While being ground in the mill, the coal, which may have a feed moisture of up to 15%, is dried with hot gases.
Vertical Roller Mill The vertical roller mill (VRM) shown in Figure 4 is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal
Hence, the treatment of circulating loads is essential for the energy saving and environment protection. As the breakage of coal happens in the closed industrial VSP with high air pressure, studies are mainly conducted on machines with similar structure in the lab or pilot scale (Werner et al., 1999; Schaefer, 2001; Ozcan and Benzer, 2013; Chi et al., …
Coal Mills are used to pulverize and dry to coal before it is blown into the power plant furnace.. Operation. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.
