Claims (11)
1. A rotor for a mineral breaker said rotor being of a generally drum-shaped configuration and arranged to be rotated about a substantially vertical axis said rotor having a substantially centrally positioned entry port in the upper surface thereof and at least one outlet port in the wall thereof so that material fed into the entry part is able to escape from the moving rotor via the said at least one outlet port, said rotor further comprising a detachable top plate which covers substantially all of the exposed upper internal surfaces of the rotor, said top plate being supported by side walls of the rotor.
2. A rotor for a mineral breaker as claimed in claim 1 wherein the sides and base of the rotor are fabricated from a material having a comparatively superior resistance to tensile forces relative to the qualities of the material from which the top plate is formed.
3. A rotor for a mineral breaker as claimed in claim 1 or claim 2 wherein the material from which at least lower surfaces of the top plate are formed is selected to provide wear resistance.
4. A rotor for a centrifugal mineral breaker as claimed in any one of claims 1 to 3 wherein the uppermost regions of the side walls of the rotor are provided with a rim providing an internal ledge to which outer peripheral edges of the top plate can be removably fixed.
5.
