Briquetting is a process that biomass is compressed under high pressure and high temperature. The self bonding of biomass to form a briquette involves the thermo-plastic flow of the biomass. The lignin content that occurs naturally in biomass is liberated under high pressure and temperature. Lignin serves as the glue in the briquetting process, thus binding and compressing the biomss to form into high density briquettes. During this process, no binder needs to be used. So the outputting briquette is a type of clean and green fuel that is ideal for use in furnaces, boilers and open fires. After the processing of drying and pressing, the biomass briquette is characterized by high density, small in size, better combustion, capable as the substitute for the superior coal or firewood.

2.The requirements of the raw materials suitable for making the briquette:

A.Diameter (size) :3-5mm ( if can't meet the requirement, it will need a crusher to crushing the raw material)

B.Moisture content: 8-12%, (if can't meet the requirement, it will need a dryer)

C.No much impurity in the raw material

3.Features of Sawdust Briquette Machine:

D.Stick shape with different diameter

E.The density, strength and hardness of products are very high.

F.With higher capacity and lower energy consumption.

G. Production moisture is 8-12%

H. This series of briquette machine is a new type of briquette machine, the finished products are more solid.

I.This Sawdust Briquette Machine with automatic temperature control system is designed to produce high density wood briquette stick from biomass.
