No need to add any adhesive for making sawdust briquettes

Biomass raw materials contain a large amount of lignin and cellulose. The heating ring of the briquette making machine generates high temperature to soften the lignin and increase the viscosity. Under the combined action of the screw propeller and the mold, the raw material is compressed into a dense biomass briquette. The whole process does not need to add any adhesive.
