Abstract: A scrap crushing machine comprises crushing device including a crusher rotor and at least one associated anvil, a housing accommodating the crushing device, the housing having an inlet opening and an outlet opening, a base arranged substantially under the rotor and extending from the inlet opening to the outlet opening, and an upper cover arranged substantially above the rotor and extending from the outlet opening to the inlet opening so as to define with the rotor a return chamber, separating device arranged in the outlet opening, an outlet connected with the outlet opening, and a flap arranged behind the rotor as considered in direction of rotation of the rotor and having a separating edge.

Abstract: A cap to cover all sides of the end of a supporting body of a hammer mill rotor. The cap has two side walls, each end of which is provided with an approximately rectangular opening. In the direction of rotation of the rotor, the cap has a forward transverse wall and a rear transverse wall, each of which is provided with openings for a securing element or a plug. Each transverse wall also has a planar, inwardly directed surface, with these surfaces being directed approximately toward the center of the rotor and forming equal acute angles symmetrically relative to a plane that extends through the hammer shaft and an axis of rotation of the rotor. The inwardly directed surface of the forward transverse wall rests upon a forward end face of the supporting body. A filler member having a rectangular cross-sectional shape fills the gap between the rear inwardly directed surface and a planar rear abutment surface of the supporting body.

Abstract: An arrangement of the working gap of a crushing machine having a housing in which is disposed a hammer crusher rotor via a horizontally disposed shaft. The working gap is disposed between the striking circle described by the hammers of the rotor as the latter rotates, and the bottom, trough-like inner housing surface that faces the rotor. The housing has an outlet for material that has been reduced in size, with the outlet extending tangential relative to the rotor. The housing also has an inlet that is provided with an anvil, and extends approximately radially relative to the rotor. The entire width of the working gap, when viewed in the direction of rotation of the rotor, is crescent-shaped from the anvil at the inlet to the tangential outlet.

Abstract: Lifting mechanism for a crusher having a two-part machine housing and a horizontal rotor with striking tools, where the plane of separation between the lower housing part and the upper housing part of the machine extends through the plane of the central axis of the rotor, where the upper housing part of the machine can be raised about a pivot axis that is disposed parallel to the axis of the rotor via piston-cylinder units that are disposed on both sides, and can be fixed in the raised position, and where the base of each of the two rotor shaft bearing housings is detachably secured to a floor stand on the lower housing part of the machine; the piston of each piston-cylinder unit is pivotably connected with a pivot arm mounted on the side of the upper housing part of the machine, with the free end of each pivot arm being fixable, via a securing mechanism, on the upper housing part of the machine in two different positions, and with the underside of each pivot arm being provided with a coupling mechanism for c

Abstract: An arrangement for reinforcing and spacing annular hammer rotor disks which are securely mounted on a rotor shaft. Disposed between these disks, there are provided pivotable, replaceably mounted hammers which are offset over the periphery of the rotor and are disposed at a distance from one another. The hammers located close to one another in a row are mounted on a common supporting rod which is parallel to the axis of rotation. A plurality of U-shaped replaceable strips, each of which is provided with a crosspiece, can be placed and secured on one of the annular disks in the circumferential direction thereof. The crosspiece of one strip rests against the crosspiece of the adjacent strip, and the intersection of the abutting ends of two strips is disposed in a radial plane of one of the supporting rods. Each crosspiece, at least on a long side and near an end, is provided with a cutout which corresponds approximately to the radius of pivot and thereof approximately to half the width of the hammer.
