Biomass pellet machines mainly use various crop residues as raw materials, such as corn cobs, soybean stalks, small wood chips,sawdust, straw, cotton stalks, rice straw, rice husks, peanut shells, bamboo powder, palm shells, and forage (the raw materials need to be crushed to some extent). Through grinding and pressing by a disc, high-density pellets are produced. The high-density biomass fuel made in this way is an ideal alternative to coal, natural gas, electricity, and oil, which can save energy and reduce pollution emissions, providing both good economic and social benefits. It is a clean, environmentally friendly, and renewable energy machine.
