The MAIER Drum Chipper HRL 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.
