wood sawdust block making machine

1 Introduction of   wood sawdust block making machine

This Wood briquettes extruder also called biomass briquette machine and sawdust briquette making machine, is used to make sawdust into halfstick. It is equipped with the autocontrolling heating system. The byproduct of this machine can be used to heat boiler, fireplace, etc for warm in house. Using the inherent characteristics of wood raw materials, through the screw extrusion, high temperature, high pressure, the wood raw material to make microfiber lignin plastics combine to form a fuel rod. It is the main equipment to make stick solid fuel with such wood material as bits of wood, rice shell or peanuts shell, etc. The raw material(12% Water proportion) dried by the dryer(12% humidity)will be formed into fuel under high pressure and at high temperature. During this process, no need to use binder and noxious chemical.

2 Working Principle of    wood sawdust block making machine

Briquetting is a process that biomass is compressed under high pressure and high temperature.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, compressing the biomass to form into high density briquettes.During this process, no binder needs to be used. So the output briquette is a type of clean and green fuel that is ideal for use in furnaces, boilers and open fires. The density of the briquettes is 900-1400kg/m2. 

3 Working process of   wood sawdust block making machine

1. Crush the raw material into small pieces (diameter is about 3-5mm)

2. Dry the material by machine or dried it in the sun , till the moisture is less than 12%

3. Put the material into briquette press machine without add any chemical goods, it should accord to the high temperature

4. Produce the briquette stick from biomass material without any additive

5. Carbonized the briquette stick

6,Finished briquette have 50MM,70MM diameter can be choice

5 Raw material

Sawdust, rice husks, seed shells, walnut shell, twigs, bark, sediment, vinegar residue, furfural residue, wood chips and various crop stalks are all appropriate materials for briquetting production. Two requirements for raw materials: 1. is size requirement (particle size less than 1cm) 2. is moisture content requirement (below 12%).
