Distributor plate

A rotor for a comminution apparatus, the rotor being arranged to launch material to be comminuted towards a contact 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 contact 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 contact 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.
