The sawdust briquette machine is usually used in the charcoal production line. The biomass materials for briquetting by the sawdust briquette extruder machine should be crushed by the wood crusher first, like bamboo, wood branches, fruit shell, straw (including paddy straw and wheat straw), corn stalk, cotton stem, and so on.
These biomass materials’ diameter should less than 5mm. And then these biomass materials should be dried by the airflow dryer or rotary dryer to reduce their moisture content below 12%. In the end, the sawdust briquettes making machine can extrude the biomass powder into biomass briquettes(pini kay)without any binder.
The sawdust briquette machine adopts electric heating, which can pyrolyze the lignin in the raw materials so that the raw materials such as rice husk or sawdust can be bonded together.
In addition, the screw propeller inside the briquettes extruder machine can extrude the sawdust from the molding die to produce solid biomass rods of various shapes. The produced biomass briquettes can usually be used directly as fuels, or they can be reprocessed to make charcoal products.
