Large wood pellet machine can produce and process all kinds of wood chips, such as: eucalyptus wood chips, pine wood chips, birch chips, poplar wood chips, fruit wood chips and crop straw, bamboo chips into sawdust and chaff processing into biomass fuel production machinery. The equipment adopts a variety of forming technologies such as cold pressing and extrusion, and the oil polishing and finishing process makes the biomass particles beautiful in appearance and compact in structure. Wood pellet machine solves the shortcomings of difficult granulation of biological coarse fiber and poor effect, the main drive adopts belt drive, the ring die adopts fast discharge hoop type, the feeding adopts frequency conversion speed regulation feeding to ensure uniform feeding, the door cover is equipped with forced feeders, the advanced manufacturing process can be customized for your various pellet machine with high-quality molds for various raw materials, so that the equipment life is extended. Product quality improved, ton consumption cost decreased. The main drive of the wood pellet machine adopts high-precision gear drive, the ring die adopts quick-discharge hoop type, the whole machine transmission part adopts high-quality bearings from Switzerland and Japan to ensure transmission stability and low noise, the ring die adopts quick-discharge hoop type, the feeding adopts frequency conversion speed regulation to feed, ensuring uniform feeding, the door cover is equipped with a strong feeder with an advanced level of compensation type snake spring coupling. It has novel structure, compact, safe, low noise, low fault, strong machine fatigue resistance, continuous production, economic and durable.

　　1. The main drive adopts high-precision gear drive, and the ring die adopts quick-discharge hoop type, which is about 20% more efficient than the relative belt drive type.

　　2. The transmission part of the whole machine adopts high-quality imported bearings and oil seals to ensure stable transmission and low noise.

　　3. Compensation type snake-spring coupling, with novel structure, compact, safe, low fault and other performance.

　　4. Strengthen the working intensity of the main working parts from the material, heat treatment and other processes, so as to meet the granulation requirements of biomass particles.

　　5. Add non-stop refueling system, air cooling system, low energy consumption, stable operation, stable and reliable grain quality.

　　The working process of the wood pellet machine is to require the water content of 13% to 17% of the material, from the storage bin into the uantitative conveyor, through the quantitative conveyor's frequency conversion speed regulation motor, to obtain the appropriate material flow, and then into the temperer, and then into the forced feeder, into the pressing chamber for
granulation.
