Ⅰ Usage and features

This machine is the main equipment to make stick shape solid fuel with such wood material as sawdust, rice shell, peanuts shell, and much other biomass material. The raw material (with 12% moisture content) will be formed into wood briquette under high pressure and at high temperature.

This machine is equipped with temperature adjusting indicator, it can work steadily at the fixed temperature. This machine is characterized by rational structure, easy for operation and maintenance. The wood briquettes produced by this machine has the feature of longer combustion time, with higher calorific value (over 20% higher than natural wood), little pollution when burning, high density and convenient for transportation.

 

Ⅱ Working principle

Using the intrinsic attributes of the wood material, by spiral extruding at high temperature, under high pressure, wood element in wood material becomes plastic and makes the fine fiber reorganize and combine again, and then stick solid fuel is formed.
