Abstract

1280062 Roller-and-ring mills POLYSIUS AG 27 May 1970 [30 July 1969] 25412/70 Heading B2A A roller-and-ring mill comprises a grinding zone 2 and a superposed separating zone 3. Rollers 6, which may be spring-urged, cooperate with a grinding surface 4. An annular arrangement of guide vanes 9 surrounds the periphery of the grinding surface to direct a supply of air which conveys the ground product from the grinding zone to the separating zone 3. The separating zone 3 includes a fan 12 mounted on adjustable arms 14. The fan causes an air stream to flow and return coarse material to the grinding zone 2. The fan shaft 13 is cooled by air flowing through a surrounding tube 15. A further ring of guidevanes 19 is arranged between the grinding and separating zones and a hopper 20, below the ring, returns the coarse material to a central conical distributor 5 of the grinding surface. Material to be ground may be supplied via an inlet duct 22 or via a hollow central shaft. Air and fine material are removed at 18 and separated externally. Alternatively separation may take place in the mill.
