Abstract: A wear plate for a rotor for a comminution apparatus that is arrangeable adjacent to at least one of the wall elements and/or a further wear plate. The wear plate extends between an upper plate and a lower plate along a longitudinal direction. The wear plate includes a first body extending along a first general direction and has an upper surface, a lower surface, and a first abutment surface extending at least partially between the upper and lower surfaces. The wear plate includes a second body extending along a second general direction differing from the first general direction and has an upper surface, a lower surface, and a second abutment surface extending at least partially between the upper and lower surfaces. The wear plate is configured to abut a first surface and a second surface of the rotor such that, in use, forming a self-locking mechanism due to rotational force.

Abstract: A rotor for a comminution apparatus. The rotor includes a frame including an upper plate, a lower plate and wall elements. The rotor further includes an inlet opening in the upper plate and one or more outlets located between the upper plate and the lower plate. A distributor plate is arranged at an upper surface of the lower plate below the inlet opening and is arranged to launch the material towards a contact surface. The distributor plate includes a cavity being open at a lower surface of the distributor plate. The rotor further includes attachment means for maintaining the distributor plate at the upper surface of the lower plate. The attachment means are arranged to frictionally engage with a corresponding surface of the cavity and the attachment means enable the distributor plate to be repositioned into different wear positions.

Abstract: The disclosure relates to a rotor for a comminution apparatus, the rotor comprising: a frame including an upper plate, a lower plate and wall elements; an inlet opening in the upper plate and one or more outlets located between the upper plate and the lower plate; and a distributor plate arranged at an upper surface of the lower plate below said inlet opening wherein the distributor plate is arranged to launch the material towards the surface, wherein the distributor plate comprises a cavity being open at a lower surface of the distributor plate, wherein the rotor further comprises attachment means for maintaining the distributor plate at the upper surface of the lower plate, wherein said attachment means are arranged to frictionally engage with a corresponding surface of the cavity and wherein the attachment means enable the distributor plate to be repositioned into different wear positions.
