A biomass briquette machine is a device that compresses biomass materials, such as agricultural waste, forestry residues, or sawdust, into solid fuel briquettes. These briquettes are a renewable alternative to coal or firewood for heating and energy production.

The briquette machine is a screw-type extruder for producing briquettes as fuel from biomass materials. So it is also called a wood charcoal machine.

The biomass sawdust briquette machine can convert the wood chips, sawdust,peanut husks, bagasse, and other wood materials into hollow-rod solid fuel(Biomass Charcoal) under high temperature and pressure conditions.
