Distributor plate

A method for repositioning a distributor plate in a rotor for a comminution apparatus, the rotor being arranged to launch material to be comminuted towards a surface, the rotor comprising:

• a frame including an upper plate, a lower plate and wall elements extending between the upper plate and the lower plate;
• an inlet opening in the upper plate and one or more outlets located between the upper plate and the lower plate, wherein the inlet opening is arranged to receive the material and wherein the material is launched through the one or more outlets towards the surface;
• 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,
• the method comprising:
• providing attachment means to the upper surface of the lower plate,
• attaching the distributor plate to the upper surface of the lower plate with the attachment means, wherein said attachment means are arranged to frictionally engage with a corresponding surface of the cavity and wherein the attachment means is arranged for maintaining the distributor plate at the upper surface of the lower plate, and
• repositioning the distributor plate by rotating the distributor plate into different wear positions.
