Abstract
A rotor protection plate for mounting on an upper plate of a rotor body of a crusher, in particular a vertical shaft impact crusher, is provided. The rotor protection plate comprises a body having an inner face defining a guide slot that is operably arranged to be in register with a rotor tip block opening defined on the upper plate of the rotor body and spaced apart therefrom to allow for a rotor tip block to be partly inserted into the guide slot during removal of the rotor tip block from, or insertion of the rotor tip block into, the rotor body.
Claims5
A rotor arrangement comprising:
- a rotor body comprising an upper plate and a lower plate, wherein the upper plate and the lower plate each define circumferentially spaced rotor tip block openings, and wherein the circumferentially spaced rotor tip block openings defined by the upper plate and the circumferentially spaced rotor tip block openings defined by the lower plate are aligned so as to form an insertion passage for accommodating at least a rotor tip block therein;
- and
- a protection plate for mounting on the upper plate, the protection plate comprising a body having an inner face defining a circumferentially extending guide recess, wherein the guide recess is operably aligned with and spaced from the circumferentially spaced rotor tip block openings defined by the upper plate, with the guide recess being configured to allow for the rotor tip block to be partly inserted thereinto during removal of the rotor tip block from, or insertion of the rotor tip block into, the rotor body.
