The biomass pellet function can take agricultural and forestry processed waste such as sawdust, straw, rice husk, bark and other biomass as raw materials, and solidify it into high-density pellet fuel through pretreatment and processing. It is an ideal fuel to replace kerosene, can save energy and reduce emissions, and has good economic and social benefits. It is an efficient and clean renewable energy source. In recent years, environmental problems have become more serious, and the biomass energy production industry has emerged. Environmental problems are improved by making straw, sawdust, etc. into pellets instead of coal. Biomass fuel pellet machines are divided into flat mold biomass pellet machines and ring mold biomass pellet machines. Scope of application and application: This product is suitable for pressing difficult to bond, forming rare materials such as rice husk, sunflower shell, peanut shell, etc., various kinds of melon shells, branches, trunk bark and other wood scraps, various crop straws 4, rubber cement ash and other chemical raw materials used in feed factories, wood processing plants, fuel plants, fertilizer plants, chemical plants, etc., and is a compression dense molding equipment with small investment results and no risk.
