for crushing and refining for crushing in wet or mixed with water faserstoffmaterial

摘要

Apparatus for the crushing or grinding of fibrous material, wet or mixed with water, preferably chips, with an engine-driven horizontally supported rotor having at least two crushing or grinding elements or grinding plates whose surfaces are inclined to the rotor axis of extend approximately normally thereto, and have diameters increasing away from at least one material feed which is directed approximately radially to the rotor axis or approximately tangentially to the rotor or stator, and a housing receiving the rotor having corresponding inner wall and opposing crushing or grinding surface or grinding plates forming grinding gaps inclined to the rotor axis or extending approximately normally thereto and being adjustable between crushing or grinding elements or grinding plates of the rotor as well as corresponding opposing crushing or grinding elements or grinding plates or the like of the interior housing walls. 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 is displaceable in the housing approximately parallel to the rotor axis, the displaceable stator ring being adjustable independently of one another by means of adjusting means acting on its outer jacket and piercing the housing shell.
