MRE Rotor Debarker

MRE Rotor Debarker

The MRE Rotor-Debarker offers the efficient continuous debarking of round wood. The logs are laterally fed into the trough, set into rotating Motion by long rotors with debarking tools and moved to the discharge area by the tilt of the rotors.

HRL Drum Chipper

HRL Drum Chipper

The HRL Drum Chipper is a tried-and-trusted solution for the production of high-quality chips from different wood assortments.
The material is gripped horizontally by specially toothed infeed rollers and continuously fed to the chipping rotor. The knives of the rotor cut the material to the required chip length. The chipped material passes an individually adapted refractioning grid.

MRZ Knife Ring Flaker

MRZ Knife Ring Flaker

After passing the vibration conveyor, the magnet drum and the heavy particle separator, the chips are distributed in 3 dimensions (3D) across all areas of the flaking chamber by the unique FlowOptimizer. Finally the fast rotating main rotor guides the chips to the knives of the static knife ring, where the chips are cut into flat uniform high quality flakes.

News & Innovations

NEW!!! MAIER Knife Ring Flaker MRZ with FlowOptimizer 

Uneven material distribution in the flaking chamber is a well-known problem of knife ring flaker systems. As a result, the total installed knife length cannot always be used evenly. This causes uneven wear of the flaker components responsible for the cutting conditions and flake quality. The ne...| » Further reading
