Wood Pellet Production Line
Product Application
1. Wood Pellet Production Line , widely used in large, medium and small wood pellet manufacturers to produce high quality wood pellet fuel for sale.
2. This machine can be used in the biomass and waste material such as :wood log ,sawdust ,shaving , rice husk, straw, cotton stalk, wood chips, palm shell , sunflower, olive, bagasse, and other raw materials.
Make pellet request:
- Material Size : < 5mm
- Moisture : 12-15% according to different material .
Typical process flow –wood logs is example into wood pellets:
Debarking → Cosrse cutting - Chipping → Milling → Drying → Pelletizing → Cooling → Bagging (the storage system shall be designed when the line is automatic )
Related equipment :
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
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.
Wood pellet machine :90-220kw
Storage system :
Moving floor is a hydraulically-driven moving-floor conveyance system for moving bulk material or palletizedproduct, which can be used in a warehouse, loading dock or semi-trailer. It automates and facilitates loading and unloading of palletized goods by eliminating the need for a forklift to enter the trailer.In thoes system ,it can storage in large amount and avoid block of sawdust ,wood chip .The moving floor can be used in storage silo ,open concrete made storage system .
Storage silos are cylindrical structures, typically 10 to 90 ft (3 to 27 m) in diameter and 30 to 275 ft (10 to 90 m) in height with the slipform and Jumpform concrete silos being the larger diameter and taller silos. They can be made of many materials. Wood staves, concrete staves, cast concrete, and steel panels have all been used, and have varying cost, durability, and airtightness tradeoffs. Silos storing grain, cement and woodchips are typically unloaded with air slides or augers. Silos can be unloaded into rail cars, trucks or conveyors
