Abstract

783,451. Roller and roller-and-breast mills. SCHOFFEL, L. Feb. 28, 1955, No. 5962/55. Addition to 746,185. Class 59 [Also in Group XXIX] The apparatus of the parent Specification, which may be used to apply pressure to the movable rolls of a three-roll grinding mill, and which enables the first roll to exert a greater pressure against the central roll than that exerted by the final roll, is modified to enable a different pressures to be applied to the two cylinders associated with either the first or the final roll, to compensate for wear of the rolls or their bearings. A supply line from a pump leads to a main regulating valve and thence to a duct 6 having a relief valve 8. Subsidiary lines 13 lead from the duct 6 to cylinders at either side of one roll, balls 15, 16 controlling communication between the lines 13 and the inlet duct 6 and an exhaust duct 9. Each ball 15 is spring-urged to its closed position and through a distance piece 20 urges ball 16 to its open position, the position of the balls 15, 16 being adjusted by a spindle 19 so as to control the pressure in the associated cylinder. The arrangement may be used to apply different pressures to the ends of the bar of a single roll mill.
