Abstract: A locking device for a crusher rotor of a horizontal shaft impact crusher includes a locking-wedge having a first through bore, a screw element for driving the locking-wedge into a locking position between a rotor arm and the hammer element and for holding the locking-wedge in the locking position, thereby fixing the hammer element to the rotor disc, a locking nut for receiving the locking screw element, and a locking nut holder. The screw element is at least partly located in the first through bore and extends through the locking nut. The locking nut holder holds the locking nut in a manner that prevents the locking nut from rotating as the screw element is driven through the locking nut.

Abstract: An abrasion resistant wear plate is mountable within a rotor or a vertical shaft impact crusher to protect the rotor from material fed into the rotor. The wear plate includes a main body that mounts and supports at least one abrasion resistant insert to define, in part, a contact face over which feed material is configured to flow.

Abstract: A rotor positioning device in a crusher is arranged to adjust a rotational position of a rotor shaft. A shaft engager includes a female toothed mating surface for coaxial engagement with a male mating surface at an end of the rotor shaft, so they become rotationally interlocked. The shaft engager includes alignable indicator slots that are, when in use, alignable with markings associated with an end of the rotor shaft, such that the markings become visible through the slots as the rod is rotationally driven by a drive component. The markings correspond to hammer positions within the crusher, such that these can be manoeuvred for maintenance (e.g. to top dead-center positions) before access to the crusher chamber is gained.

Abstract: An abrasion wear resistant distributor plate assembly is mountable to protect a rotor within a vertical shaft impact crusher for material fed into the rotor. A distributor plate is configured to be resistant to the operational abrasive wear resulting from contact with a flow of crushable feed material through the crusher rotor. Attachment components are provided around a perimeter of the plate to facilitate mounting and decoupling of the plate at the rotor during servicing or replacement procedures.

Abstract: A rotor locking device in a crusher is arranged for locking a rotational position of a rotor shaft. A shaft engager includes a female toothed mating surface for coaxial engagement with a male mating surface at an end of the rotor shaft to rotationally interlock the same. A fastening portion with engager apertures overlaps with a bearing mount surrounding the rotor shaft so it can be fastened therewith. The engager apertures are circumferentially elongated in order to accommodate alignment with fastening points in the bearing mount, at least when a closest rotational mating position is chosen for alignment. This enables any rotational position of the rotor shaft to be locked for safety before having to access the crusher chamber, especially when the rotor of the crusher has become blocked and requires maintenance.

Abstract: A locking device for a crusher rotor of a horizontal shaft impact crusher including at least one hammer element and at least one rotor disc having a plurality of rotor arms. The locking device includes a locking-wedge having a first engagement surface for engaging one of the rotor arms and a second engagement surface for engaging the hammer element. An installation handle of the locking devices is arranged to move the locking-wedge to a locking position where the first engagement surface engages the rotor arm and the second engagement surface engages the hammer element.

Abstract: A rotor positioning device adjusts a rotational position of a rotor of a horizontal shaft impact crusher. The device is mountable to an external region of a main frame of a crusher so as to releasably couple to an exposed end of a main shaft of the rotor. The device includes a shaft engager capable of being moved to and from engaging contact with the rotor shaft end. A drive component provides rotational drive of the rod to impart rotational adjustment of the position of the rotor shaft.
