Raw and Auxiliary Materials
Raw and Auxiliary Materials 

The raw materials used in the processing project of the biomass pellet production line are mainly bamboo shavings, sawdust, wood shavings, branch wood, straw and other agricultural and forestry wastes. Bamboo shavings mainly come from bamboo chopsticks processing plants, and sawdust and shavings mainly come from wood processing plants. The source of raw materials for the project is sufficient to fully guarantee the operation of the project. The transportation of raw materials is entrusted to the social forces to be transported in, and they are all transported back to the raw material warehouse of the factory area by the way of truck shed cloth for stacking. The raw material warehouse is semi-closed and not stacked in the open. The fuel required for the dryer of this project is the biomass pellets produced by the project itself, and high-polluting fuels such as coal are not used. The main raw and auxiliary materials and energy consumption are shown in Table 1-3.

7. Process Flow of Biomass Pellet Production Line Processing Project

The main raw materials of this project are agricultural and forestry wastes (bamboo sawdust, shavings, straw, etc.), which need to be sliced, crushed, dried and processed according to the moisture content and particle size of the purchased raw materials before granulating.

(1) Chipping: Use a chiper to cut the straw, branch materials, and large pieces that cannot be directly crushed into small pieces.

(2) Crushing: The agricultural and forestry waste is crushed by a crusher to make the particle size less than 5mm. The pulverizer is only equipped with a feed port and a discharge port. The feed port is closed after feeding to reduce dust escape. The discharge port is connected to a cyclone separator. The cyclone separator uses the principle of centrifugal force to separate the scraps, and the scraps are deposited in the dust collector , The gas is discharged through the material port, and the gas is discharged from the cyclone separator and then processed by the bag filter. All the collected dust is recycled to the production line.

(3) Drying: Some raw materials that account for 30% of the total have a moisture content of 55% (the data provided by the owner is between 50% and 60%, and this environmental assessment takes 55%), which does not meet the requirements of granulation Claim. These raw materials with excessive moisture content need to be dried to make the moisture content meet the granulation requirements (the moisture content is less than 13%), and the moisture content of the raw materials after drying is about 10%. The dryer of this project is equipped with a biomass burner, and the fuel is biomass pellets produced by the project.

(4) Conveying and feeding: the raw materials are sucked into the feed port of the granulator through the feeding auger.

(5) Granulation: the raw materials are fed into the pellet machine through the feeding auger, and the finished product is formed by extrusion molding. The extrusion process is a physical process without any adhesive and no chemical reaction occurs, except for the feeding auger connection The equipment is sealed at and outside the discharge port. This process mainly produces noise and high-temperature dust-containing waste gas;

(6) Lifting and conveying cooling: The pelletized biomass particles are naturally cooled by conveying, so that their temperature can reach the conditions of packaging and storage, and finally conveyed to the finished product warehouse. This process generates dust and noise.

(7) Packing: The compressed hot particles pass through the screening at the end of the conveyor belt, and the qualified biomass particles fall into the finished product warehouse. The bottom of the finished product warehouse is a funnel-shaped discharge port. The finished product can be directly dropped into the packaging bag. After the machine is packaged, it can be stacked for sale. After molding, the biomass particles have been compacted and dense, and there is basically no dust during the bagging process. The unqualified products are discharged and collected and then returned to the granulation process.
