Our biomass briquette machine uses a large screw to grind, compress and extrude the biomass into briquettes. The natural lignin content in biomass is liberated with wood fiber under high pressure and temperature. In the briquetting process lignin serves as the glue and combines the particles of wood together, thus binding, compressing the biomass to form into various moulds of high density briquette, such as hexagonal, quadrangular, square, etc. During this process, non-binder needs to be used.Our biomass briquette machine has automatic temperature control system, which is designed to produce high density wood or biomass briquettes as bio-fuel. The biomass briquettes are quite popularly used in boilers, furnaces and so on.
