摘要： A drum refiner for grinding fibrous material, preferably chips, has an engine-driven drumshaped rotor which is placed on a horizontal shaft. The rotor has grinding surfaces extending parallel to the rotor axis and corresponding opposing grinding surfaces arranged on the housing. The grinding elements are placed symmetrically about at least one material feeds which are conveniently evenly distributed around the circumference of the rotor. The grinding surfaces begin parallel to the axis and contiguously increasing in inclination forming a grinding gap inclined towards the rotor axis at an angle of approximately 5.degree. to 45.degree., preferably 15.degree.. The second embodiment includes grinding surfaces contiguously increasing in inclination and ending with an angle of inclination of approximately 90.degree. to the rotor axis.

摘要： The invention relates to a crushing or grinding element for drum refiners having an engine-driven rotor for the crushing or grinding of fibrous materials. The element is attachable to the rotor shell and has crushing or grinding surfaces of increasing diameter and optionally crushing or grinding surfaces of steeper inclination to the rotor axis immediately adjacent the crushing or grinding surfaces inclined to the rotor axis provided on the rotor shell. The grinding surfaces are symmetrical to the median plane of the material feed. The invention is characterized in that the crushing or grinding element(s) is (are) formed as (a) segment(s) placed around the circumference of the rotor having anchoring projections of hammerhead-like cross section on the side facing the rotor axis and which are engageable in corresponding rotor grooves of hammerhead-like cross section.

摘要： A grinding element for a drum refiner for the crushing or grinding of fibrous material. The drum refiner includes an engine driven rotor having a generally horizontal rotor axis and at least one material feed. A rotor jacket is positioned on the rotor and has a surface of revolution. The grinding element is attachable to the rotor jacket on the surface of revolution and has a diameter increasing away from the material feed. A housing receives the rotor and rotor jacket therein, and has an opposing inner wall with a corresponding grinding element thereon. The grinding element on the rotor jacket includes a channel spaced from the material feed for the discharge of steam. The channel has one end in fluid communication with the grinding gap and a second end in fluid communication with a bore extending generally normally to the channel. The bore is in fluid communication with a cavity in the housing. The improvement comprises the grinding element on the rotor jacket being generally formed of a segment. The grinding element includes a surface facing the rotor axis and an anchoring projection of hammerhead-like cross section extending from the surface facing the rotor axis. The anchoring projection is engageable in a generally corresponding rotor groove of hammerhead-like cross section in the surface of revolution, such that the segments serves for the discharge of steam and is locked to the rotor jacket.
