Pellets made from mechanically processed biomass particles can be used as concentrate feed, saving costs and increasing farmers' income. They can also be used as fuel, which can reasonably replace non-renewable energy sources such as coal, gas, and crude oil, and can be used to a certain extent. Improve the energy structure, increase the efficiency of electric energy, and alleviate consumption and environmental pressure. It is not difficult to see that the development and application of biomass fuel pellet machines have played a very important role in our production and life, which has greatly facilitated our lives.
