The biomass pellet mill has standard requirements for raw materials in the production process. Too fine raw materials will cause the biomass pellet forming rate to be low and more powdery. The quality of the formed pellets made by biomass pellet mill also affects the production efficiency and power consumption.
Generally speaking, raw materials with small pellet size are easy to compress, and raw materials with large pellet size are more difficult to compress. In addition, the water resistance, hygroscopicity and molding density of the raw materials are closely related to the size of the fuel pellets made by biomass pellet mill.
When the same material with different pellet sizes is at low pressure, the larger the pellet size of the material, the slower the molding density changes, but as the pressure increases, the difference becomes less obvious when the pressure reaches a certain value.
Pellets with a small pellet size have a large specific surface area, and wood chips are easy to absorb moisture and regain moisture; on the contrary, because the pellet size of the pellets becomes smaller, the gaps between pellets are easily filled, and the compressibility becomes larger, which makes the residual internal content inside the biomass pellets. The stress becomes smaller, thereby weakening the hydrophilicity of the formed block and improving the water resistance.

1. What are the standards for biomass raw materials?
What are the standards for raw materials in the production of biomass pellet mill? Of course, there must be a small limit to the small size. If the pellet size of the wood chips is too small, the mutual inlaying and matching ability of the wood chips will be reduced, resulting in poor molding or reduced resistance to breaking. Therefore, it is better not to be less than 1mm.
The size should not exceed the limit. When the pellet size of the wood chips is greater than 5MM, it will increase the friction between the pressing roller and the abrasive tool, increase the extrusion friction of the biomass fuel pellet machine, and waste unnecessary energy consumption.
Therefore, the production of biomass pellet mill generally requires that the pellet size of the raw material be controlled between 1-5mm.
2. Pellet fuel from biomass pellet mill
Biomass pellet fuel is a kind of renewable new energy, which utilizes plant wastes, such as sawdust, branches and sapwood, corn stover, rice straw and rice husk, and is made into pellets through the biomass pellet mill and biomass pellet production line.
Pellets made by biomass pellets making machine are fuels for direct combustion, which can indirectly replace coal, oil, electricity, natural gas and other energy sources.
Combustion heat loss (Q4) is basically zero, coal fired furnace Q4 is 7-15%, and our ST is 0.41 with a large amount of coal, the difference in SO2 emissions after combustion is 20.5 times. Therefore, in addition to alternative fuels such as coal and oil, biomass pellet fuel can reduce air pollution, make SO2 and CO2 harmful gases, and achieve essentially zero emissions.
Biomass pellet fuel made by biomass pellet mill mainly comes from wood processing, forest pruning and other wastes and crop straw, raw material sources are wide, China is rich in resources, easy to invest in production, it is cheaper than coal and has higher thermal efficiency.
Pellet fuel is in line with my country’s industrial policy and our province’s overall plan for energy conservation and emission reduction. At the same time, waste recycling can increase farmers’ income and employment, add new fuel to the countryside, and improve farmers’ quality of life.
The biomass pellet fuel processed by the biomass fuel pellet machine also has good combustion performance similar to briquette, and has the advantages of less sulfur content, less ash content and lighter environmental pollution than coal.
Compared with firewood, biomass pellet fuel has low water content, high specific gravity and high calorific value, which is beneficial to improve the thermal efficiency of biomass pellet fuel furnace. Therefore, biomass pellet fuel is widely used in biomass straw power plants, boilers of enterprises and institutions, biomass straw gasification stations, household stoves, European heating furnaces, etc., thereby replacing coal and solving environmental pollution problems.
Biomass pellet fuel made by biomass pellet mill machine can be used in textile, printing and dyeing, paper, food, rubber, plastic, chemical, pharmaceutical and other industrial products, and can be used for heating, bathing, air conditioning and daily heating in enterprises, institutions, hotels, schools, restaurants, and service industries. water.
Compared with other production methods, biomass pellet mill has the characteristics of simple production process, simple equipment, simple operation, easy to realize industrial production and large-scale use.
Effective development and utilization of solidified crop straws can replace raw coal to effectively alleviate energy shortages, control organic waste pollution, protect the ecological environment, and promote harmony between man and nature.
According to statistics, burning 10,000 tons of wood pellets as an environmentally friendly fuel can replace 8,000 tons of traditional coal, and the price ratio is indeed 1:2. Assuming that the traditional coal is converted into environmentally friendly fuel wood pellets every year, the price of using 10,000 tons of pellets will save 1.6 million yuan per year compared to coal and 1.9 million yuan compared to natural gas.
At present, many areas still use natural gas, coal, etc., where the use of boilers requires thermal energy, the use of wood pellets, an environmentally friendly and low-cost fuel, can be promoted.
Wood pellets made by biomass granulator mainly use agricultural and forestry wastes such as straw, rice husks, straw, cotton stalks, husks, branches, and sawdust as raw materials, which are processed into shaped pellet fuels and applied in various industries.
The function of biomass pellets has also been improved. It will expand the larger development and application fields, and promote the biomass pellet mill to have more development space.
