Abstract
856,027. Sifting apparatus. DUNBAR, J. R. March 3, 1959, No. 7339/59. Class 117 A classifier for pulp stock &c. includes a number of co-operating rolls 1, 1A...1I, rotatable at the same speed and in the same direction, and each roll has a number of angularly disposed grooves 2, Fig. 3, of uniform depth arranged so that the groove angles on adjacent rolls are oppositely disposed to each other, and so that each space 3 between the grooves on one roll substantially covers the opening made by a groove on an adjacent roll. The grooves thus covered by the spaces define the acceptable openings for the stock which is fed to the rolls via an inlet 4, reservoir 5 and baffle 6; accepted stock passes to an outlet 8 and reject to an outlet 7. Sets of sprays 9A, 9B, 9C and 10. 10A, 10B remove stock adhering to the rolls. Each roll may be composed of a number of discs of two different diameters but of the same thickness mounted at an angle to the roll axis.
