‌The main functions of producing pellets from sawdust include the following aspects:

‌Civil heating and life energy: Sawdust pellets have a high combustion utilization rate, are easy to store and use, and are safe and hygienic. For example, Beijing's boilers are widely popular in household use.

‌Replacement of coal and oil: Sawdust pellets can be used as the main fuel to replace coal and oil and reduce dependence on fossil fuels.

‌Power generation: Sawdust pellets can be used as solid biomass fuel for power generation. Every 10,000 tons of sawdust pellets burned can replace 8,000 tons of coal, reduce SO2 emissions by 160 tons, smoke emissions by 80 tons, and CO2 emissions by 14,400 tons.

‌Animal feed: The high fiber and low protein content of sawdust pellets make it an ideal animal feed, which can enhance the nutritional value and taste of the feed.

‌Wood product production: Sawdust pellets can be used as raw materials for particleboard production, with better ductility and flexibility, and more affordable prices.

‌Environmentally friendly materials‌: Sawdust particles can be mixed with resin, natural fiber, sand and other materials to produce environmentally friendly building materials such as ecological bricks and ecological boards, which have heat preservation and sound insulation effects.

‌Organic fertilizer‌: Sawdust can be fermented to improve the soil and used as a mixture for organic fertilizer.

‌Making nutritious soil for flowers and trees‌: After mixing sawdust with human feces and urine for fermentation, it can be made into nutritious soil for flowers and trees to promote their growth.

‌Farmyard manure‌: Sawdust and loess are mixed in a certain proportion, and human feces and urine are added to make efficient farmyard manure.

‌Fermented mattress material‌: Sawdust is loose and porous, with good water retention and air permeability, and is suitable as a fermented mattress material for cultivating edible fungi.

In short, sawdust particles have a variety of uses. They can not only be used as energy and feed, but also can be used in the production of wood products, the production of environmentally friendly materials, and agricultural fertilizers, and have broad application prospects.

The general process of producing pellets from sawdust is as follows:

Raw material preparation: Make sure the quality and moisture of the sawdust meet the production requirements. If the sawdust is too wet, it may need to be dried.

Crushing: Use a crusher to crush the sawdust into smaller particles for subsequent processing.

Screening: Remove impurities and oversized particles from the sawdust through screening equipment.

Mixing: Sawdust can be mixed with other additives (such as adhesives, preservatives, etc.) as needed to improve the quality and performance of the pellets.

Pelletizing: The mixed sawdust is fed into the pellet machine and made into pellets through extrusion and friction.

Cooling: The newly made pellets are at a high temperature and need to be cooled to prevent deformation and adhesion.

Screening: The cooled pellets are screened to remove particles that do not meet the requirements.

Packaging: Qualified pellets are packaged for storage and transportation.
