The screw shaft on briquette machine is the key to make briquettes and charcoal. The quality of the screw shaft is related to the stable production of the briquette machine, therefore, the screw shaft of briquette machine is necessary to have the following characteristics to ensure the stable, outstanding operation state of briquette machine. 

Screw shaft of briquette machine must have high strength first. Due to the inductive effect of compression, torsion and bending during the operation of the screw shaft, especially when metal or other hard objects are stuck in the screw shaft, if the power can not be immediately blocked, the screw shaft will have a huge stress, therefore, the demand of the screw shaft should have a higher strength.

Screw shaft of briquette machine should also have high wear resistance. There is friction between the material and the surface of the screw shaft in the operation, especially the head of the screw shaft will have a great friction resistance, it needs to have a strong anti-abrasive wear ability, which needs to improve the fineness and surface hardness of raw materials. If the external hardness reaches Vickers hardness, the wear resistance of the screw shaft will be greatly improved.

Screw shaft of briquette machine also has high heat resistance. In order to make the loose material to be condensed forming, the material temperature is often maintained between 140 degrees Celsius and 160 degrees Celsius. Therefore, the mechanical properties of the screw shaft should be the same at least 300 degrees Celsius.
