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.
Claims16
An abrasion wear resistant plate mountable to protect a rotor within a vertical shaft impact crusher from material fed into the rotor, the wear resistant plate comprising:
- a metallic main body including a work plate having a plurality of holes, wherein each of the plurality of holes extend completely across a depth of the work plate;
- at least one non-metallic tile secured within each of the plurality of holes in the work plate of the main body to form at least part of a planar contact face arranged to face material fed into the rotor, the at least one non-metallic tile having an abrasion wear resistance greater than that of the main body, wherein the at least one non-metallic tile is substantially free of tungsten carbide;
- and
- a support plate non-detachably coupled to the work plate via mating contact between an upward facing surface of the support plate and a downward facing planar surface of the work plate, wherein each at least one non-metallic tile is secured within each of the plurality of holes in the work plate such that a downward facing surface of the at least one non-metallic tile is mated against the upward facing surface of the support plate.
A distributor plate releasably mountable to protect a rotor within a vertical shaft impact crusher from material fed into the rotor, the distributor plate comprising:
- an abrasion wear resistant plate, the abrasion wear plate including a metallic main body having a work plate including a plurality of holes, wherein each of the plurality of holes extend completely across a depth of the work plate;
- at least one non-metallic tile secured within each of the plurality of holes in the work plate of the main body to form at least part of a planar contact face arranged to face material fed into the rotor, the at least one non-metallic tile having an abrasion wear resistance greater than that of the main body, wherein the at least one non-metallic tile is substantially free of tungsten carbide;
- and
- a support plate non-detachably coupled to the work plate via mating contact between an upward facing surface of the support plate and a downward facing planar surface of the work plate, wherein each at least one non-metallic tile is secured within each of the plurality of holes in the work plate such that a downward facing surface of the at least one non-metallic tile is mated against an upward facing surface of the support plate.
A protective wear part arranged to sit radially outside a central distributor plate mountable to protect an upper or lower disc of a rotor within a vertical shaft impact crusher, the protective wear part comprising an abrasion wear resistant plate including a metallic main body having a work plate having a plurality of holes, wherein each of the plurality of holes extend completely across a depth of the work plate, and at least one non-metallic tile secured within each of the plurality of holes in the work plate of the main body to form at least part of a planar contact face arranged to face the material fed into the rotor, the at least one non-metallic tile having an abrasion wear resistance greater than that of the main body, wherein the at least one non-metallic tile is substantially free of tungsten carbide, and a support plate non-detachably coupled to the work plate via mating contact between an upward facing surface of the support plate and a downward facing planar surface of the work plate, wherein each at least one non-metallic tile is secured within each of the plurality of holes in the work plate such that a downward facing surface of the at least one non-metallic tile is mated against the upward facing surface of the support plate.
