3-4t/h Biofuel Wood Sawdust Pellet Production line
Wood pellet production line is amid to make wood log ,chip ,sawdust into pellets .
To make the pellet ,it should be follow the requirements :
- Particle Size : < 5mm
- Moisture Content : 12-15%
- Suitable Raw Material : Softwood, Hardwood, Mixed Wood ,straw ,bamboo ,agriculture waste
Typical process flow –wood logs is example into wood pellets:
Debarking → Chipping → Milling → Drying → Pelletizing → Cooling → Bagging

Wood chipper :
To chip the wood log into 20-30mm chips .
Drum wood chipper series products are production of special equipment, the product is widely used in particleboard factory, medium and high density fiber board factory, stubble plant, biomass wood pellet plant, wood factory and other industries and manufacturers in the production of equipment for preparation before the section. This product structure is advanced, high-quality cutting blade material, the raw material adaptability, convenient operation and maintenance. Cutting path is the main raw material of wood, wood cutting, processing residues, such as branches, branches, slab, slat cores, logs, veneer scrap, etc.), can be used to cutting non-wood raw materials (such as sugar cane, reed, bamboo, etc.).

Hammer mill :
To mill the wood chip into 6mm sawdust .
Advantage:
High milling efficiency, uniform milling , strong anti-blocking ability for high moisture and high grease materials, wide applicability, long life of hammer and screen. The Supreme Hammer Mill is with reasonable design and excellent manufacturing. It adopts SKF bearings, famous brand motors and brand-name couplings. The main vulnerable parts are metal wear-resistant materials, which adopt high-precision rotor dynamic balance. After the final assembly, the 3D vibration intensity test is completed.
With US PATENT WHICH WITH HIGHER CAPACITY COMPARED WITH SAME POWER AND MATERIAL :
The screen would be vibrating on the working which solve problems that high moisture difficult to discharge .
Increased hammer impact plate, added more hits, high efficiency, for wood material milling, the impact part of the chamber is made of manganese steel, wear-resistant and impact resistant.
Rotary Dryer : Reduce the moisture of wood sawdust.
Under the suitable size of raw material ,the moisture is requested between 12-18% ,if more water content would cause cracked pellet ,if less would no formed . So dryer is necessary when moisture is out of requested arrangement .
The wet material is conveyed by screw . Feeding side generate hot air (furnace ,boiler etc)with wet material is sucked into inner of dryer by draught fan . As the dryer rotates continuously, the water inside material is evaporated by three ways .Another benefit of heating the toughness is enhanced, thereby increasing production efficiency, especially those with higher density, such as hardwood. Heating enhances the toughness of the raw materials and acts to soften the natural lignin in the raw materials.
Ring Die Pellet Mill : Make 6-8mm wood pellets.
Cooler : Cool down hot wood pellets, not higher than room temperature 3-5 ℃.
Bagging Machine : Pack finished pellets into bags.
