Abstract: Pulp grinder intended for cellulose, paper or other equivalent pulp and comprising at least one non-rotating blade disk and at least one rotating blade disk with grinding surfaces opposing each other, the non-rotating blade disk being secured to the body of the grinder by the use of three fixing pins, by the aid of which the grinding surfaces can be adjusted to be parallel. At least one fixing pin is heatable, and thus changeable as to its length, for instance with the aid of electric current, of a temperature-controlled fluid or vibration.

Abstract: The object of the present invention is a pressure straining device for cellulose, paper or equivalent pulp suspension, comprising at least one straining cyliner through which the acceptable pulp is strained and in connection with which there has been provided at least one blade rotating about the axis of the straining cylinder, extending over the straining surface and moving at a small distance from this surface, which blade cleans the surface of the straining cylinder facing the pulp to be strained, and which blade has a substantially drop-shaped crossed section and contains a hollow space, extending from one end to the other, for collecting pulp to be rejected, this hollow space opening through a slit towards the straining cylinder so that on either side of the slit flanges substantially pointing towards each other are produced, and said hollow space communicating at one end with a venting space, located at one end of the pressure straining device, for the pulp to be rejected. The blade has been shaped so that on its side toward the straining cylinder it substantially follows the shape of the straining cylinder, that the leading flange of the blade has been given such a direction that its forward edge is closer to the straining surface than its free rear edge and that the free forward edge of the trailing flange is located closer to the straining surface than the free rear edge of the leading flange.
