Abstract

The invention relates to an apparatus for the crushing or grinding of fibrous material, in particular fibrous material wet or mixed with water, preferably chips, in paticular to drum refiners, with an enginedriven rotor having at least two crushing or grinding elements whose surfaces, conveniently rotation surfaces, in particular frustroconical surfaces, are inclined to the rotor axis or extend approximately normally thereto, and have diameters increasing in the direction away from the at least one material feed and a preferably horizontal rotary shaft as well as a housing receiving the rotor having (a) corresponding inner wall(s) and opposing crushing or grinding surfaces disposed thereon, the at least one material feed directed approximately radially to the rotor axis or approximately tangentially to the rotor jacket or housing shell being positioned approximately in the center of said housing and the crushing or grinding surfaces extend from the material feed way on both sides of the jacket of the rotor and correspondingly on the inner housing wall on the inclined or approximately normally extending surface, conveniently rotation surface, in particular frustroconical surface with diameters increasing away from the material feed and the latter surfaces enclose an angle open to the front faces of the rotor on both sides with the axis of the rotor. The invention is mainly characterized in that crushing or grinding surfaces extending approximately parallel to the rotor and corresponding opposing crushing or grinding surfaces arranged on the housing are provided on the jacket of the drumshaped rotor between the material feed as well as that the crushing or grinding surfaces forming the grinding gap extending parallel to the axis and the grinding gap inclined to the axis and the opposing crushing or grinding surfaces are disposed symmetrically in relation to the median plane(s) of the at least one, advantageously two or more material feed(s) conveniently evenly distributed over the circumference of the rotor, in particular approximately radially or approximately tangentially, and that the crushing or grinding surfaces parallel to the axis are followed immediately, in particular merging constantly, by the in particular frustroconical crushing or grinding surfaces inclined towards the axis of the rotor at an angle of approximately 5 to 45 degrees, in particular 15 degrees, said inclined crushing or grinding surfaces optionally being followed immediately, in particular constantly, by merging crushing or grinding surfaces with an angle of inclination larger than the angle of the aoresaid inclined crushing or grinding surfaces, in particular of nearly or approximately 90 degrees, to the rotor axis.
