33 Tons/hour Biomass Wood Pellet Production Line Construction Project

33 tons/hour biomass wood pellet production line construction project, the annual operation days of the project is about 300 days, 10 hours a day, purchase 8 biomass pellet machine, an average of 4 tons/hour per pellet machine. The biomass fuel produced by this project is a solid fuel produced by extruding wood chips and rice husks from waste wood and furniture factories in Lanxi area. It is easy to store, transport, easy to use, and does not have any harmful additive combustion efficiency. High, clean and environmentally friendly, it can be used for civilian purposes and can replace coal as fuel for industrial boilers. After the project is completed and put into production, it will solve the reuse of waste materials such as chaff waste, increase employment, protect the environment, and promote local economic development. It has good economic and social benefits.

2. Process Flow Description

Raw and auxiliary materials entering the factory: The raw and auxiliary materials used by the company are waste wood, wood chips and chaff. Wood needs to be crushed into small wood chips with a drum chipper, and then crushed into wood chips with a hammer mill.

Screening: The raw material sawdust and chaff are screened to remove other impurities such as stones in the chaff.

Granulation: The sieved sawdust and rice husk are formed in a wood pelletizer through a conveyor belt, and heated by the pelletizer's own equipment. The temperature of the wood chips and chaff can reach 80℃ to 90℃, and the pellets are extruded. The fuel is continuously extruded to the outer end of the die hole, and the shaped particles are cut into the required length by the cutter, and finally the shaped particles flow out of the pelletizer and fall into the product conveyor.

Cooling: The temperature of the pellets is as high as 80-90℃ when the pelletizer is discharged, and must be cooled to room temperature before being put into storage. This project adopts wind cooling. Since the biomass particles have been compressed and dense, there is basically no dust generated during the cooling process.

Screening and storage: The cooled biomass particles are sent to the finished product warehouse by a conveyor. The conveying equipment is equipped with a sliding screen. The particles that meet the required size enter the finished product warehouse, and the non-compliant biomass particles fall into the lower layer of the screen. It is discharged before entering the finished product warehouse and reused in the granulation process. Qualified biomass particles fall into the finished product warehouse, and the bottom of the finished product warehouse is a funnel-shaped discharge port, which is pneumatically discharged. The finished product can be directly dropped into the packaging bag and packaged with a baler before being sold. The formed biomass particles have been compressed and compacted, and there is basically no dust during the bagging process. After the unqualified products are discharged, they return to the forming process.
