APPARATUS FOR PRODUCING DISINTEGRATED MATERIAL, PREFERABLY PULP ABSTRACT OF THE DISCLOSURE Method and apparatus for controlling the refining of fi- brous lignocellulose pulp material in which the pulp stock or grist is conveyed into a cylindrical stationary drum and propelled therein in a linear direction in a pulsating fashion by a co-axial rotor comprising a plurality of impellers which attach the grist in a wedging action as it is compacted by the centrifugal force of rotation and pushed ahead of the leading edges of the impellers and thus inducing in the grist internal frictional shear forces while it is forced through a gap defined between the terminal edges of the impellers and a series of shear members arranged axially along the interior surface of the drum. The impellers are de- tachably and adjustably anchored in slots in the peripheral wall of the drum to vary the gap clearance. A plurality of adjustable plow members for enhancing the linear flow of the grist through the drum may be additionally mounted in the peripheral wall of the drum to extend radially inwards to engage accommodating slots in the impellers to thereby regulate the amount of grist pushed ahead during each revolution of the impellers and to control the centrifugal force exerted on the grist.
