Drum Chipper

The drum chipper can cut logs, branches, boards, waste veneers, bamboo, cotton stalks and other non-wood fiber stems into a certain size of sheet material, as at least particle board, fiberboard, non-wood wood board and pulp and paper. The basic raw materials, advanced machine structure, high quality of cutting sheet material, wide adaptability of raw materials, convenient operation and maintenance

The wood is fed from the feed port. When the wood is contacted to the cutting blade, the cutting is followed by the high-speed rotation of the cutting blade. The cutting mechanism is a rotating drum with a plurality of flying knives mounted thereon, and the flying knife rotates. Wood is processed into wood chips. There are a plurality of square through holes on the outer edge of the drum. The cut pieces pass through the mesh holes and are discharged at the bottom. The large pieces will be cut again in the machine.

(1)New design blade rotor,blades are easy to replaceable.
(2)Cover of crushing chamber could be opened by hydraulic,ease for maintenance and changeble blades.
(3)Screen mesh size is customized for different requirements on size of end product. Hydraulic buffer system ensures smooth operation.
(4)Reverse feeding device,belt conveyor can be reversed positively.This device can protect machine,when large wood is encountered.
(5)Higher capacity than the traditional type,larger feeding size,could chipping log diameter 230-500mm.

The drum chipper is composed of a body, a knife roll, an upper and lower feeding mechanism, a hydraulic system, a feeding device and the like.
1.The body: welded by high-strength steel plate, is the support foundation of the whole machine.
2.Knife roll: Two or three or four flying knives are installed on the knife stick. The fly knives are fixed on the knife roll by a pressure block.
3.Hydraulic system: It is supplied to the cylinder by the oil pump, and the cover can be activated to facilitate the replacement of the blade; the upper feeding roller assembly can be lifted during maintenance, which is convenient for adjusting the gap between the flying knife and the bottom knife and the disassembly and assembly of the comb plate.
4. Upper and lower feeding mechanism: consists of feeding interface, upper and lower feeding rollers and feeding gap adjusting mechanism. The wood entering from the feeding interface is pressed by the upper and lower feeding rollers, and is fed to the cutting mechanism at a certain speed. Controls the size of the cutting chips; when processing thick wood, it is adjusted by the feed gap mechanism.
