Biomass briquette press machine at http://www.biomass-briquette.com/.
Screw type briquette press can produce biomass briquettes with higher compaction. After feeding, the material is conveyed to the briquette forming head by a revolving screw shaft driven by electrical motor or biodiesel motor. The screw shaft is the main part of biomass briquette press. The screw distance become smaller and smaller along the screw shaft to briquette froming head. With the decreasing screw distance, the material endures bigger and bigger pressure. At end, different shapes of biomass briquettes form out under huge pressure from revolving screw shaft. Because of the shaft, there is a hole left in the center of biomass briquette column.

The screw pressure is bigger than jam pressure, so the biomass briqettes have high density which is easy for transport and storage. Compared to solid, the hollow in center of biomass briquettes makes for burning. With these good features, screw type biomass briquette press is more popular in the production.
