Our Briquetting Presses are in screw type, it produces hollow hexagonal or quadrangular cylinder with a 15-20mm hole through the body. The briquettes produced by a screw press is easily handled and stacked, and
they have some advantages over those produced using the ram and die press, such as better efficient
combustion due to the central hole and carbonized outer layer. Our biomass briquette machine have automatic t
emperature control system, it is designed to produce high density wood or biomass briquette as biofuel.
Briquetting is a process that biomass is compressed under high pressure and high temperature. The machine
uses a large screw to grind, compress and extrude the biomass into briquettes. The self bonding of biomass to
form a briquette involves the thermo-plastic flow of the biomass. The natural lignin content in biomass is
liberated under high pressure and temperature. Lignin serves as the glue in the briquetting process, binds the
particles of wood together, thus binding, compressing the biomass to form into high density briquettes. During
this process, no binder needs to be used. So the ouput briquette is a type of clean and green fuel that is ideal
for use in furnaces, boilers and open fires.
