Briquetting Bar Press/Biomass Briquette Machine/Briquetting Screw Press

Briquetting is one important process that biomass is compressed under high pressure and high temperature form into different shapes. The 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 biomss to form into various moulds of high density briquette, such as hexagonal, quadrangular, square, etc.During this process, no binder need to be used.
