Drum Chipper

Drum chipper is a specially designed equipment for producing wood chips. It is widely used in the material preparation section of wood chip mills, particleboard, fiberboard, paper mills, biomass fuel plants, etc.

The raw materials processed by the drum chipper are mainly logs, waste wood, wooden pallets, building templates, nailed boards, wood cutting residues (branches, twigs, etc.), and wood raw material processing residues (slabs, slats, round wood cores, waste veneers, etc.), which can also be used to cut non-wood materials (such as sugarcane, reed, bamboo, etc.).

The drum chipper is composed of a base, a blade roller, an upper and lower feeding mechanism, a feeding belt conveyor, a hydraulic buffer system, a discharging belt conveyor, and an electrical control system. The chipper body is welded with a high-strength steel plate, which is the supporting foundation of the whole machine.

Unlike the disc chippers, the blades of the drum chippers are mounted on the cutter roller. 2-4 blades are mounted on the blade roller, and the blades are fixed on the blade roller by means of pressure blocks with specially manufactured blade bolts. According to the different thicknesses of the raw materials, the upper feeding mechanism can be opened and closed within a certain range with the help of a hydraulic system. The cut-qualified chips fall through the screen holes and are discharged from the bottom. The large wood chips will continue to be cut in the machine until they are finally discharged through the screen.
