The raw material is compressed into pellets using a fuel pellet making machine.
The powder is fed into the two pressing areas in the ring die by the feeding scraper. Due to the high-speed rotation of the fuel pellet machine ring die, the material is brought between the ring die and the pressing roller.
Under the strong pressing action of the ring die and the pressing roller, the The material is gradually compacted and formed in the fuel pellet machine die hole. Since the extrusion of the material between the die rollers is continuous, the formed material is continuously discharged from the die hole in a columnar shape, and then cut into the required appropriate length by the cutter pellet.)
The temperature of the newly pressed fuel pellets is relatively high, the structure is relatively loose, and it is easy to break. It must be cooled to room temperature.
The vibrating screen is used for screening, and the debris is screened out to ensure the quality of the biomass pellet fuel.
The finished biofuel pellets are sent to the finished product warehouse through the elevator, and are transported to customers in bulk or packaged according to pellet fuel manufacturers’ needs.

The growing biomass pellet fuel industry
At the end of the 20th century, biomass was put forward as a special concept, and began to be systematically developed for industrialization, but the proposed perspective, concept and connotation are not consistent. It is generally believed that biomass mainly refers to renewable or recycled organic matter, including crops, trees and other plants and their residues; there are also considerations of efficient utilization of resources and circular economic benefits, and it is proposed that biomass is non-food lignocellulose. substance..
There are many types of biomass resources, mainly including agricultural waste and agricultural and forestry product processing industry waste, fuelwood, human and animal manure, and urban domestic waste. Biomass energy is the energy stored in biomass, which is stored in biomass by green plants converting solar energy into chemical energy through chlorophyll. Energy shortage and environmental crisis are two major problems restricting the economic and social development of the world today. Biomass energy has gradually become an important new energy because of its renewable, rich resources and friendly to the ecological environment.
In recent years, the social and economic development of human beings has become increasingly rapid, but this is at the cost of consuming a large amount of fossil energy and polluting the environment. Fossil energy is decreasing day by day, and environmental pollution is becoming more and more serious. It is urgent to find a renewable alternative energy.
Biomass energy is a kind of renewable energy with dual attributes of renewability and environmental friendliness. In recent years, more and more attention has been paid to biomass energy, and its consumption has jumped to the fourth place after oil, coal and natural gas.So, you can start focusing on starting a fuel pellet plant business.
Supplementary information of fuel pellet production
What’s fuel pellets?
Biomass pellet fuel is a solid renewable fuel with a diameter of ≤25mm, an aspect ratio of ≤4, and common diameters of 6, 8, and 10mm. It can be processed by cold compact molding from crop wastes such as straw, rice husk, peanut husk, or various raw materials such as pine, fir, birch, and poplar. After the biomass pellet fuel is compressed and molded, its volume is greatly reduced, which makes it more convenient for transportation, storage and use. It is widely used in industrial and agricultural production, power generation, heating and heating, boiler burning, and unit households.
Compared with ordinary wood fuel, biomass pellet fuel has the advantages of high density, high strength, easy transportation and loading and unloading, uniform shape and properties, good combustion performance, high calorific value, strong adaptability, and convenient fuel operation and control.
Characteristics of biofuel pellets
Under the action of a certain external pressure, the biomass raw materials such as wood and straw will reach a certain temperature due to the mutual friction between the materials and between the materials and the mold roll, and the bonding effect of the lignin will make the plant body denser.
Evenly, when the external pressure is removed, the original structure and shape cannot generally be restored due to the mutual entanglement between fiber molecules. After cooling, the strength increases and becomes a pellet fuel.
The higher the volatile content of the pellets for fuel, the easier it is to ignite and the better the combustion performance. The volatile content of biomass pellet fuel is as high as 60% to 70%, which is much higher than that of coal, so its ignition performance and combustion performance are better than coal.
The carbon content is 35% to 42%, which is much lower than that of coal, which makes its calorific value lower than that of coal; the N content is 0.5% to 3%, and the S content is only 0.1% to 0.5% t. The emission is much lower than that of coal, and the CO2 emitted and the CO2 absorbed by straw photosynthesis reach a balance, basically achieving zero emissions; compared with the original biomass resources, the burning time of pellet fuel is longer. It can be seen that biomass pellet fuel is a kind of “high-quality, clean and efficient” fuel.
Physical and chemical properties of biofuel pellet
The components of biofuel pellets are combustible matter, inorganic matter and water, and the specific indicators are as follows. Calorific value 20.24 MJ/kg, fixed carbon 15.58%, volatile matter 84.22%, carbon 49.72%, oxygen 35.81%, hydrogen 5.79%, sulfur 0.06%, nitrogen 0.16%, ash 1.26%, moisture 7.2%.
In Europe, fuel pellets quality standards are established by the European Committee for Standardization (CEN).
If the scale of feed production is expanded, it is necessary to increase the number of poultry feed pellet making machine or poultry feed production lines, and thWood ash content varies according to soil type, tree age, site (needles, branches and bark) and harvest season. The minerals absorbed by the tree from the soil are mainly distributed to needles or leaves, small diameter branches and bark. The mass fraction of needle ash in conifers is about 5%, the bark part is about 3%, and the trunk is 0.5%.e total investment price will basically increase proportionally.
The ash content of pellet fuel is relatively high when the parts used in the fuel pellet plant granulation process are mainly bark and needles. The EU standard states that the ash content of the highest quality pellet fuel should be no more than 0.7% of the dry mass of the pellet fuel. The ash mass fraction of the black pine trunk was 0.23% to 0.28%, and the ash mass fraction of the whole European red pine tree was 1.1%.
Mechanical durability is a very important quality parameter of pelletized fuel, because in the process of loading, unloading, transportation and storage, pellet fuel with low mechanical strength is easily broken, resulting in the increase of powder and affecting the feeding. At the same time, during the combustion process, also affects flue gas emissions.
A standard test for mechanical durability is by tumbling the pellet fuel and calculating the percentage of remaining pellet fuel after fines are removed. The Swedish Biomass Pellet Fuel Standard requires pellet fuels to have a mechanical durability greater than 95%.
Durability reflects the bonding performance of pellet fuel, which is determined by compression conditions and relaxation density. Durability, as an important characteristic of the quality of pellet fuel, is mainly reflected in different service performance and storage performance. The relaxed density of pellet fuel made from fuel pellet plant cannot comprehensively and directly reflect the differences in the use of briquette fuels.
Therefore, the durability is further refined into several indicators such as deformation resistance, crush resistance, rolling resistance, water permeability resistance and moisture absorption resistance.
The volume of the raw material in the mold decreases with the increase of the pressure during the compression process. When the pressure increases to a certain extent, the volume does not change any more. The density of the material in the mold under the final pressure is called the compression density.
However, after the molded pellets or agglomerates are taken out of the fuel pellet machine ring die, due to elastic deformation and stress relaxation, the volume will gradually increase, and the density will continue to decrease, and tend to stabilize after a certain period of time. This density is smaller than the final compressed density in the mold, and is an important indicator for determining the physical properties and combustion properties of the fuel in the pellet fuel.
The relaxed density of biomass fuel pellets made by fuel pellet plant is closely related to the type of biomass and the compression molding process conditions. Due to different water content and different components of biomass, the relaxed density achieved under the same compression conditions will also be significantly different.
There are generally two ways to improve the relaxed density of biomass pellet fuel:
