Abstract

684,302. Roller mills. SCHOFFEL, L. May 25, 1951 [May 26. 1950; Dec. 6, 1950], No. 12375/51. Class 59 In a roller mill having sealing cheeks 27 bearing on the ends of the rollers and supported by the side walls of a supply hopper 26, and having internal cooling means for the rollers, the cheeks are adjustable both radially and axially of the rollers, and the ends of the rollers are provided with cavities through which the cooling medium passes. The cheeks are adjustably secured by means of bolts 34 passing through slots 32 to angle pieces 28 which are adjustably secured to the side walls of the hopper by means of bolts 30 passing through slots 29. The end faces of the cheeks are provided with inclined surfaces 36 so that any material passing over the ends of the rollers is returned to the peripheral surface of the rollers. The ends of the rollers are provided with radial ducts 4 communicating with transverse bores 5 in the ends of the rollers and with holes 10 in the shaft 3 Cooling medium is supplied through a tube 9. The latter may open through a bend 37 into a radial bore of the shaft 3, in which case the tube is rotatable with the shaft, and the cooling medium is returned through the ducts 4. In a modification, Fig. 3 (not shown), the ducts in the ends of the rollers are formed by tubular members around which the rollers are cast or moulded. In a further modification, Fig. 4 (not shown), the ends of the rollers are formed with stepped recesses which are covered by flange plates.
