Advantages of biomass fuel pellet machine

  • The method of compact molding at room temperature is adopted. The friction heat generated during the extrusion molding of the material can soften and bond the material;
  • The requirements for the moisture content of the raw materials are relatively wide;
  • High production efficiency, greatly improved output, relatively good product quality, uniform product particle size and high density;
  • Low energy consumption cost;
  • Small equipment size, simple and practical design;
  • No binder is added, which effectively reduces production costs and makes the product more natural and environmentally friendly.

Working principle of biomass fuel pellet machine

The crushed biomass wood material enters the die cover by the forced feeding mechanism, and is fed evenly into the two pressing areas in the ring die, that is, the wedge-shaped space formed by the two rollers and the ring die, through the centrifugal force generated by the feeding device and the rotation of the ring die and the action of the feeding scraper.

Under the strong extrusion of the ring die and the roller, the material is gradually compacted, squeezed into the die hole of the ring die and formed in the die hole.

Since the extrusion of the material between the ring die and the pressure roller is continuous, the formed material is continuously discharged from the die hole in a columnar shape and then cut into biofuel pellets of the required length by the cutter.

How to process biomass pellets with complete biofuel pellet machine plant?

The production process of biomass pellets produced by ring die compression consists of cleaning, crushing, drying, pelletizing, cooling, screening, and packaging systems.

The process flow of complete biofuel pellet machine plant mainly includes raw material processing, crushing, drying, granulation and packaging.

How to process biomass pellets with complete biofuel pellet machine plant
  1. Raw material processing:
    The collected biomass raw materials, such as wood, straw, etc., are pre-treated by impurity removal, shearing or shredding to remove impurities for subsequent processing.
  2. Crushing:
    The pre-treated raw materials are sent to the crusher, and after crushing, pulverizing and other operations, the raw materials are further refined into smaller particles to improve the uniformity and operability of the particles.
  3. Drying:
    In the drying equipment, the granular raw materials are dried to remove moisture from the raw materials and improve the combustion efficiency and quality stability of the pellets.
  4. Granulation:
    The dried raw materials enter the biomass fuel pellet machine, and the raw materials are formed into regular granular materials by extrusion, pressing and other methods under high temperature and high pressure.
  5. Cooling:
    The granulated biofuel pellets are cooled by the cooling device to prevent the biofuel pellets from absorbing moisture during packaging and storage.
  6. Screening:
    The cooled bio fuel pellets enter the screening device and are screened through screens of different particle sizes to separate biofuel pellets that meet the requirements.
  7. Packaging:
    The screened biofuel pellets are packaged through an automatic packaging machine, generally in woven bags or plastic bags for storage and transportation.

The slicer is used to crush and finely crush large wood raw materials. If the raw materials for making biomass pellets are large-volume raw materials such as logs, construction waste, branches, etc., they cannot be directly crushed and pelletized, so they need to be crushed before proceeding to the next process.

(If the size of the raw material is within 15mm, such as wood chips, sawdust, etc., the biomass pellet production line does not need to be equipped with a comprehensive crusher.)


The diameter of the crushed biomass raw material is generally around 10-15mm, which cannot meet the optimal pelletizing requirements. At this time, the raw material needs to be crushed. The crusher can crush the crushed material by replacing the screen to make the raw material reach the expected size. Generally, the optimal pelletizing raw material size is within 6mm.

RICHI recommends that the production line with large wood materials as raw materials is equipped with two crushing processes: coarse crushing and fine crushing. This can not only fully crush the raw material, but also reduce the loss of internal parts of the crusher and reduce processing costs.

Drying machine

Biomass pelletizing has certain requirements for the moisture content of the raw material. The vertical pellet machine and the flat die pellet machine have relatively strict requirements for moisture content, which generally need to be controlled within 15%. If the moisture content exceeds 15%, it will affect the pelletizing efficiency, and even blockage or no discharge will occur.

The moisture requirement of the horizontal pellet machine is relatively loose. It is generally recommended to be 15-20% for the best, and pelleting can be done if it does not exceed 30%. If the moisture content of the raw materials entering the factory is high, they need to be dried.

There are many types of drying furnaces. When selecting bio fuel pellet making machine, pay special attention to its efficiency. Since the drying furnace is a high-energy-consuming equipment, RICHI recommends using biomass pellets for heat source, which is much cheaper than electric heating and natural gas heating.

Biomass fuel pellet machine

The processed raw materials are extruded and pelletized by the biofuel pellet mill.

As the most important section of the biomass fuel pellet plant, the operation of the bio pellet machine is simple, but various situations may occur in daily operation, such as uneven discharge, unformed discharge and other raw material adaptation problems, and accessories such as mold roller wear. If you encounter related problems, you can consult the equipment manufacturer for after-sales service in time.


In addition to the above raw material processing equipment, there are some other auxiliary machines: transportation system, silo, dust removal system, vibrating screen, cooling system, finished product warehouse, and packaging system.

This type of equipment is conducive to biomass pellet manufacturing plant management. Usually, equipment manufacturers assist customers in making complete equipment production line solutions to achieve integrated control, reduce production costs, and make the production line run efficiently.
