Roll-Bowl COP - A full featured mill monitoring solution

Coal grinding is performed by quickly rotating rotor by means of impact and grinding effect. Milled coal is removed from grinding area by drying agent to separator where the segregation of large-sized coal fractions from air-and-coal mixture and their return for finish grinding occur. The adjustment of finished pulverized coal fineness is provided by moving blade. The blade is controlled by worm gear drive.
