3. Brief Description of Process Flow

After the project materials are collected, they are stacked in the material warehouse for later use. The raw materials are sent to the granulation machine through the conveyor belt to be mixed, pressurized, and densified. After simple packaging, they are put into storage for sale. Unqualified products can be reused as raw materials, reprocessed, and recycled. The formed biomass fuel is small in size, large in specificity, resistant to combustion, and convenient for storage and transportation.
