The Coal Briquette Machine facilitates the clean utilization of raw coal. As a type of clean coal production technology, it boasts simplicity in operation, mature technology, low cost, significant energy-saving and efficiency improvement, and reduced exhaust emissions. The Coal Briquette Machine utilizes the screw extrusion principle to compress well-mixed coal powder into briquettes with certain strength, either in a cylindrical or梅花-shaped design. It employs variable pitch impellers to propel the coal powder at the rear of the cylinder forward with great force. As the coal powder is compressed within the drum, it is extruded through the round orifice of the front head, forming coal briquettes. The shapes of these round orifices and the briquettes themselves can vary.
