Amount of raw and auxiliary materials:

The raw materials used in this 2.5t/h wood pellet processing equipment project are wood scraps. During the production process, the raw materials will be lost due to the formation of dust due to crushing, pressing and molding processes. Pollution production coefficient is 6.69×10-4t/t-product), that is, the loss is 4.014t.

About 90% of the lost dust is collected into the pulse bag filter for treatment, and most of it is collected as raw and auxiliary materials after being treated by the pulse bag filter, and the dust that has not entered the pulse bag filter is discharged in the workshop without organization.

Most of them are settled on the workshop floor by gravity and collected by the construction unit as raw and auxiliary materials for reuse. Through calculation, the amount of recycled dust is 3.6046t.

It can be calculated that 6004.014 tons of raw materials are needed to produce 6000 tons of biomass pellets. Among them, 3.6046 tons of raw materials are recycled dust, so the annual consumption of raw materials is 6000.41 tons.

The villages near this project are mixed industrial and residential villages, and most of the industries are wood processing industries. Therefore, it is very convenient for customers to purchase raw materials.

Wood Pellet Process Design

The granulation production process of this project is: crushing-crushing-feeding-granulation-cooling-packing and storage

1. Chipping: Put the waste wood raw materials into the chipper and cut them into small pieces. Due to the large particle size of the raw material, there is basically no dust on the conveyor belt. The slicer operates in a semi-closed manner, and the upper part is the feeding port. After slicing, the material is basically still in the form of strips, and the particle size is relatively large.
2. Crushing: Put the chipped waste wood into the crusher through the loader and crush it into plate materials with a particle size of about 10 cm to 80 cm.
3. Screening: The crushed material is automatically conveyed to the screening machine by the closed conveyor belt to select some scrap metal and other waste impurities mixed in the raw material.
4. Grinding: The screened materials are automatically conveyed to the mill for further grinding through the closed conveyor belt. The grinding diameter is 12mm. The grinding process is carried out in a closed manner, which will generate a small amount of grinding dust.
5. Granulation: After grinding, the product is transported to the wood pellet press granulator through a closed conveyor belt. The wood pellet machine is the key equipment of the production line. The raw material contains a certain amount of cellulose and lignin, and the lignin is the structural monomer in the material.
   It is a high molecular compound, which can strengthen the cell wall and bind cellulose. Lignin is non-crystalline, the main part is insoluble in any solvent at room temperature, has no melting point, but has a softening point.
   When the temperature reaches a certain value, the softening cohesive force of lignin increases, and under a certain pressure, the cellulose molecular clusters are dislocated, deformed, and extended, and the adjacent biomass pellets inside are engaged with each other, recombined and pressed forming.
6. Cooling: The formed biomass wood pellets are transported to the finished product warehouse by a closed conveyor belt, and are slowly and naturally cooled during the conveyor belt transmission process, without drying or drying.
   Since the pellet size of the formed biomass pellet is relatively large (diameter 8mm~10mm, length 2-4cm).
7. Packing: The cooled products are packed manually and stored for sale.

Note: The raw materials are transported to the raw material warehouse by forklifts, and the finished products are transported by forklifts.

The client company was established in September 2017. Due to market demand, the client invested 280,000 US dollars to rent an idle factory building and build a biomass pellet production line. After the project is completed, the production scale will be 8,000 tons of biomass pellets per year.

3T/H complete wood pellet production Process Flow

According to the specific requirements of customers, we can tailor-made complete wood pellet plant for sale and supporting overall design.

• ①Crushing: Due to the large waste wood and sawdust, it needs to be crushed to meet the requirements of the briquette forming process. The wood and sawdust are crushed and refined to 3-8mm by a multifunctional crusher for slicing and chipping.
  
  The pulverizer is only equipped with a material inlet and a material outlet. After feeding, close the material inlet to reduce dust escape. The material outlet is connected to a closed-air cooling and hardening dust removal tower.
  
  The tower uses the principle of centrifugal force to separate the crushed materials. The crushed materials are deposited in the dust collector, discharged from the discharge port regularly, fall into the material conveyor, and are transported to the granulation process.
• ②Granulation: The pulverized material is sent to the feeding hopper through the belt conveyor, and the electric feeding screw conveyor sends the material evenly to the granulation bin.
  
  The hole diameter of the mold is 6-10mm. Strong pressure friction occurs between the material in the granulation chamber, the pressure roller and the template to generate a lot of heat, which makes the material temperature rise to about 80-130 degrees.
  
  The wood fiber is softened and sterilized, and the whole granulation process does not use additional heat or hot steam. The wood pellet press is a closed device with only a small amount of dust escaping, and the generated dust is treated by the dust removal facilities of the equipment.
• ③Cooling: The upper part of the steam cooling dedusting tower has a strong suction pipe to draw out hot steam, moisture and dust, and the particles are cooled and hardened by rolling for 3-5 minutes to further make the product a qualified finished product.
• ④Inspection: If the inspection is qualified, it is the finished product, and the biomass pellets that do not meet the requirements will be reused in production.
• ⑤Packing and warehousing: The qualified finished products produced are packed in bags, weighed, packed, and put into warehousing for stacking.

3T/H Wood Pelleting Plant Process Design

The project puts the purchased large raw materials on the crusher for crushing through a forklift or forklift, and the small raw materials are crushed together with the crushed materials (the particle size after crushing is below 5mm). The final wood powder is transported to the granulation room of the wood pellet machine equipment through pipelines.

Through the high-speed rotation of the pressing wheel, the wood chip raw material begins to heat up and become soft (the pressure of the high-speed rotating pressing wheel can reach 300T, and the temperature of the wood chip can reach 100℃~130℃ ) , the softened and heated sawdust raw material is extruded through the holes of the formwork under strong pressure.

During this process, the density of the sawdust is increased, the moisture content is reduced, and the compression ratio is 5.5:1. Then it is naturally cooled and dried. After arriving at the finished product warehouse, it can be packaged and shipped.

During this production process, the crushing and pulverizing section is unable to be sealed, so there is dust and waste gas; because the granulation section is carried out in a closed equipment, and the biomass particles are output after being extruded under pressure, there is basically no dust and waste gas overflow at this stage.

Note: The moisture content of the raw materials of the project is 8%~15%, which meets the requirements of granulation and molding, so there is no need to dry or add water during the production process.

This project leases a factory building of 1,800 square meters on one floor. The production scale is 8,000 tons of biomass pellets per year, and the raw material is 8,900 tons of wood.
