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 particular to drum refiners with an engine- driven in particular horizontally supported rotor having at least two crushing or grinding elements or grinding plates whose surfaces advantageously rotation surfaces in particular frustoconical surfaces are inclined to the in particular horizontal rotor axis or extend approximately normally thereto and have diameters increasing away from the at least one material feed directed approximately radially to the rotor axis or approximnately tangentially to the rotor or stator as well opposed inclination towards the rotor axis and a housing receiving the rotor having (a) corresponding inner wall(s) and opposing crushing or grinding surface(s) or grinding plates the grinding gaps inclined to the rotor axis or extending approximately normally thereto being variable or adjustable between crushing or grinding elements or grinding plates of the rotor jacket as well as corresponding opposing crushing or grinding elements or grinding plates or the like of the interior housing walls. The invention is characterized in that the opposing crushing or grinding elements or grinding plates or the like are arranged or attached on at least two stator rings of which at least one for instance two is (are) displaceable in the housing approximately parallel to the rotor asxis, in particular horizontally, the displaceable stator ring(s) being adjustable independently of one another by means of adjusting means acting on its (their) outer jacket(s) and piercing the housing shell and advantageously , in particular in the case of only one displaceable stator ring, the rotor is axially displaceably supported.
