Biomass briquetting machine is a device that compresses biomass energy into blocks. The principle is to compress biomass raw materials under high temperature and high pressure, so that components such as lignin, cellulose and hemicellulose in the raw materials undergo plastic flow and form blocks of a certain shape and size. The biomass briquetting machine can compress biomass raw materials into denser blocks with a large compression ratio, thereby reducing storage space and transportation costs. The briquettes produced by the biomass briquetting machine have high density, tight internal structure and are not easy to scatter. They can be used as good fuel or feed. The briquettes produced by the biomass briquetting machine have high combustion value and can replace some traditional fuels such as coal, reducing energy consumption and pollutant emissions.
