Biomass briquetting equipment including screw-extrusion molding machines, mechanical piston stamping forming machine, ring die-roll and hydraulic piston stamping molding machines. Mechanical piston forming and

24、 hydraulic piston forming machine total up production efficiency low energy high, former of productivity low, actual productivity in 100-200 kg, main work parts life low not for industrialization production; which main work parts life long, but highest production capacity lower energy high; from tec

25、hnology index view, ring die roll pressure type forming machine production rate highest, energy low, products cost low, while technology content also high, for Yu scale production promotion. Since in the 1980 of the 20th century, Chinas bio-technology research and development have made great progres

26、s, national research and production equipment of enterprises or research institutes has dozens of homes. Chinas industrialization of biomass briquette fuel prototype is formed, however, to be mature and realize industrialization, you first need to overcome some constraints, some technical obstacles.

27、 Includes the main working parts of the short working life, poor ability to coordinate equipment systems, running unstable, and so on. Also, due to the lack of effective industrial practices, solid biomass industry is still in its infancy in China. Biomass fuel shaping technology, stable performance

28、 and low power consumption of the device is the core of industrialization of biomass fuel, good industry and the Governments support and the necessary funding is a prerequisite for industrialization of biomass briquette fuel. To compress biomass briquette processing cost, you will need to yield powe
