The MPF Prallfiner enables the continuous processing of soft to medium-hard materials into slim fine flakes or wooden powder. After passing the VC Vibration Conveyor, the permanent magnet drum and the HPS Heavy Particle Separator the material is fed from the back side into the grinding chamber, where it is milled between the rotor beater ledges and the grinding track. The final product is pneumatically discharged through the door.
