37-38 t/h turnkey wood pellet mill system Process flow:

1. Crushing: The raw materials used in this project have been briefly processed before entering the market, and impurities such as iron nails are manually removed. Large pieces of raw materials such as waste wood are fed to the crusher by forklifts for crushing to obtain crushed materials with a particle size of about <120mm. An iron remover is installed at the outlet of the crushed materials to magnetically separate iron and other impurities that may be present in the crushed materials. After crushing, Materials are stacked between the crushing area and the crusher feed port for easy transportation.
2. Hammer milling and silo: The crushed materials are fed from the loader to the feed port of the hammer mill crusher (pit type, the feeding port is parallel to the ground). When the crusher is running, the crushed materials are transported to the crusher by the belt for crushing to obtain granules. For crushed materials with a diameter of less than 5mm, an iron separator is installed at the outlet of the crushed materials. Iron and other impurities that may be present in the crushed materials are magnetically separated and discharged through cyclone separation, and then transported to the raw material warehouse through a closed belt for temporary storage until subsequent production. grain.
3. Granulation and molding: The crushed material in the silo is transported to the closed discharging auger through a closed distribution auger, and then sent to the feeding chamber of the wood pelletizer machine by an elevator. It is evenly distributed under the joint action of the distributor and scraper. The ground is laid on the die, and the pellet machine squeezes the wood chips into rod-shaped pellets through extrusion molding.
4. Air-cooling screening, packaging and packaging: The granules coming out of the wood pelletizer outlet have a high temperature, a loose structure, and are easily broken. They must be cooled to room temperature by a counter-flow air cooler and then transported to the granulator by a belt. The vibrating screen screens out unqualified products with a particle size of <8 mm to ensure the factory quality of biomass pellet fuel. Qualified products are sent to the finished product warehouse via the elevator, bagged and sealed for sale.

The road width designed at the base can ensure unimpeded access for firefighting vehicles and personnel. From the perspective of streamline organization, the flow of people and logistics are clear and basically do not cross each other, which is conducive to corporate management and the safety of corporate employees.

33-34 t/h turnkey wood pellet mill system Process flow:

1. Raw and auxiliary materials entering the factory: The raw and auxiliary materials used by the enterprise include sawdust, rice husks, and straw. The raw and auxiliary materials purchased by the enterprise are all preliminarily crushed and dried raw materials. The moisture content of the sawdust is between 6% and 12%. time, the particle size is about 3mm-20mm, the moisture content of the straw is about 12%-18%, the particle size is about 5mm-30mm, the moisture content of the rice husk is about 8%-14%, and the particle size is about 4mm- 7mm. Wood chips, rice husks, and straw do not need to be dried after being transported into the factory. Since straw and rice husk have certain seasonality, the use of raw and auxiliary materials is also subject to seasonal restrictions. During the harvest season of corn and rice, the sources of corn straw and rice husk are abundant. Enterprise production mainly uses straw and rice husk. Mainly husks, with a small amount of sawdust. In the season when there is no straw or rice husk acquisition, the company only uses sawdust for production.
2. Granulation: The raw materials sawdust, rice husks and straw are lifted by a belt conveyor, sent to the warehouse to be granulated through the material distribution auger, and formed in the granulator. The moisture content of the raw materials is no more than 18%, and the particle size is no more than 7mm. No additives are needed. The raw materials enter the granulator from the granulator bin. Through heating, the temperature of the powder can reach 80°C to 90°C, and the extruded pellet fuel continues to move out of the die hole. End extrusion, the cutter cuts the molded particles into the required length, and finally the molded particles flow out of the wood pellet press and fall into the product conveyor.
3. Cooling: When the wood pellet extruder machine is discharging, the temperature of the pellets is as high as 80~90°C, and must be cooled to normal temperature before being put into storage. This project uses wind cooling. Since the biomass particles have been compacted and compacted, there is basically no dust generated during the cooling process.
4. Screening and storage: The cooled biomass pellets are sent to the finished product warehouse by a conveyor. The conveying equipment is equipped with a sieve. Straw particles that meet the requirements of the size enter the finished product warehouse, and the biomass particles that do not meet the requirements fall into the lower layer of the screen. , discharged before entering the finished product warehouse, and reused in the granulation process. Qualified biomass particles fall into the finished product bin. The bottom of the finished product bin is a funnel-shaped discharge port, which is pneumatically discharged. The finished product can be directly dropped into the packaging bag, and can be sold after being packed with a baler. The formed biomass particles have been pressed and dense, and basically no dust is generated during the bagging process. Unqualified products are discharged and returned to the molding process.
