* Application

Hollow - Screw Briquetting Plant is for convert Biomass Powder or sawdust to Hollow Briquettes / Bio-coal. This Hollow Briquettes can be carbonized as a charcoal.

* System Description of Screw Briquetting Machine

The project is simply process of converting Agro-forestry or Bio-mass waste into Briquettes. Briquetting is a process of densification of biomass to produce homogeneous, uniformly sized solid pieces of high bulk density which can be conveniently used as a fuel.

In a screw extruder press, the biomass is extruded continuously by a screw through a heated taper die which can reduce the friction. Briquettes quality and production procedure is far superior to piston press technology. The central hole incorporated into the briquettes produced by a screw extruder helps to achieve uniform and efficient combustion and also these briquettes can be carbonized.
