This charcoal briquette machine can press the dried and screened raw materials into a rod-shaped article of 45-80 mm by high temperature and high pressure. Key components such as propulsion shafts are formulated with special wear-resistant materials and precision cast. The degree of cooperation, compactness and wear resistance between the propeller shaft and the inner sleeve barrel are greatly improved.It use sawdust, coconut shell, wood shavings, bamboo sawdust, bark, branches, walnut, chestnut shell, cotton stalk, sesame stalks, corn stalks, sunflower stalk, soybean straw, rice husk, bagasse, corncob as raw material crushing (diameter below 6mm, such as rice husk, sawdust not after crushing) by mechanical the extruded four edges, six edges or square with hole forming fuel. Fuel rods before forming mechanism of raw natural stacking density of 60-350kg/m, forming the density of 1100-1400kg/m, thus the extrusion molding fuel rod density than before forming several times to improve the ten times.
