  • Stock pulper for pulping and sorting waste paper
    Patent number: 4167249
    Abstract: The stock pulper is disposed on a vertical axis with an outlet for impurities of low specific gravity at the top. The wall of the stock pulper is conical with an upwardly directed apex to assist in the separation of the impurities. The top end wall of the stock pulper is also conical with an upwardly directed apex to facilitate the outflow of the impurities of low specific gravity. The outlet for high specific weight impurities is located at the bottom of the stock pulper.

  • Stock pulper
    Patent number: 3942728
    Abstract: The container for the stock suspension is made as a body of revolution with a conical circumferential wall and a conical end wall which defines an acute angle with the circumferential wall to facilitate separation of materials. A compartment is formed in the circumferential wall near the end wall. This compartment is of increasing radial thickness in the direction of rotation of the rotor and terminates at the location of an outlet for heavy impurities.
