biomass pellet production line construction

Applicable raw materials

Biomass is inexhaustible and inexhaustible. It is a renewable energy source and the only renewable carbon source. It usually includes wood, forest waste, agricultural waste, plants, cities and Industrial organic waste, animal manure, etc. Biomass energy resources are relatively abundant on the earth, and it is a kind of harmless energy.

There are many types of biomass, and the common biomass raw materials are wood chips and straw. Subdivisions include wood, branches, bark, furniture factory waste, building templates, wooden pallets, corn straw, wheat straw, rice husk, peanut shells, etc.

biomass pellets Production process design

Crushing (cutting, chipping, grinding)—drying—granulation—cooling—packaging.

According to different raw materials and different customer needs, the production process of biomass pellets is quite different. Therefore, if you want to build a biomass pellet production line, please tell us your needs, your pellet plant area, raw materials and other factors, and we will customize the most suitable process for you.

  1. Slicing: Agricultural and forestry waste enters the warehouse through a transporter, is sliced by a slicer, and then enters the wood chip warehouse. It is screened through a vibrating screen to screen out uniform wood chips, and then enters the water washing section.
  2. Removal of impurities: The impurity removal system cleans the wood chips cut into specifications to remove mud, sand and other impurities contained in the wood chips to ensure the purity of the biomass pellet molded fuel and increase the calorific value of the fuel.
  3. Proportion: Different raw materials are mixed in a certain proportion.
  4. Drying: The hot air oven drying used in the traditional process is difficult to control the moisture and has a large error. High-temperature flue gas is used as the heating medium, and the moisture control error is within 0.01. Due to the precise control of fiber moisture, the quality and output of biomass pellet molding fuel are guaranteed.
  5. Grinding: The raw materials are fully crushed through the crushing system to facilitate the next step of granulation.
  6. Granulation: The raw materials used in biomass compression molding are various agricultural and forestry wastes such as wood, sawdust, sawdust, fruit shells, and straw. These biomass cells contain a large amount of cellulose, hemicellulose and lignin, accounting for more than 2/3 of the plant body components.
    When the temperature reaches 70-110°C, the lignin softens and the adhesion force increases; at 200-300°C, the degree of softening intensifies. At this time, external pressure is applied to bond and combine to form a biomass molded block with a certain shape.
    Since inelastic or viscoelastic fiber molecules are entangled and twisted with each other, they will not return to their original structural shape after the external pressure is removed.
  7. Then through cooling-screening-quality inspection-packaging and other processes, the biomass pellet fuel is compressed and molded.

Equipment for biomass pellet production line

The equipment used in the manufacture of biomass pellets includes: biomass crushers, pulverizers, biomass dryers, biomass pellet machines, pellet coolers, screening equipment, packaging machines, conveyors, dust removal equipment, silos,
