The drum wood chipper can process logs of different specifications and wood raw materials (branches, slivers, waste veneers, etc.) into chips with a size of 2-3 cm. It is a high-quality chip production equipment. It can also cut other non-wood raw materials, which is called coarse powder; after the fine powder of multi-functional pulverizer, the moisture can directly enter the wood pellet machine and bark pellet machine in the range of 12% -18%; 18% need to enter the tumble dryer to dry before granulation.
Depending on the thickness of the material being cut, the upper feed roller assembly can float up and down within a certain range by means of a hydraulic system. The cut qualified pieces fall through the screen holes and are discharged from the bottom. Large pieces will be cut in the machine.
Structure and characteristics of drum wood chipper:
The drum wood chipper is composed of a body, a knife roller, an upper and lower feeding roller, a conveyor belt, a hydraulic system and the like. The body is welded with high-strength steel plates, which is the supporting foundation of the entire machine. Two or three or four flying knives are installed on the knife roller, and the specially made flying knife bolts are used to fix the flying knife on the knife roller through the pressure block. Depending on the thickness of the material being cut, the upper feed roller assembly can float up and down within a certain range by means of a hydraulic system. The cut qualified pieces fall through the screen holes and are discharged from the bottom. Large pieces will be cut in the machine.
Hydraulic system: supplied by the oil pump to the oil cylinder, the cover can be activated to facilitate the replacement of the blade; the upper feeding roller assembly can be raised during maintenance to facilitate the adjustment of the gap between the flying knife and the bottom knife and the disassembly and assembly of the comb plate.
