【Name】:Screw Type sawdust briquette machine with a hole in briquette center

【Application Fields】This biomass briquette machine is able to make perfect briquette for home heating and barbecuing owing to burning of cleanliness and hygiene.
Product Description

The screw type sawdust briquette machine is designed to make high density wood briquette from forest waste or agricultural waste.

The final briquette shape can be hexagonal or square, with a hole in center.

The requirement of raw material:

Raw material can be the wood sawdust,rice husk,peanut shell,bamboo dust,sunflower shell,corncob,coconut shell,coffee shell,straw and other biomass materials.

Materials diameter should be less than 5mm; Moisture content should be less than 12%.

If not, please crush and dry them firstly.If you want to get briquette with high density,please add some starch.

Working Principle:

The sawdust briquette machine adopts a screw propeller to grind,compress and 

extrude the biomass material into briquettes.

Under high pressure and temperature, the lignin in biomass is liberated, 

playing the role of glue in the briquetting process by binding the wood particles together.

Material for biomass briquetting

The best materials for briquetting are sawdust and other woody residues, because these contain a high proportion of lignin. However, most dry agricultural residues can be used if they are ground into a coarse powder. Grain straw and dried grasses do not make good briquettes on their own, but work well when mixed with woody materials to provide the lignin. Bagasse, shells (such as from peanuts) husks (such as rice husks and corn cobs) and pine needles make reasonable briquettes. However rice husks are abrasive due to their silica content, and can reduce the life of machine components.
