The quality of screw shaft is related to the stable operation of charcoal machine

The screw shaft is an important part of the charcoal machine, and it is also the key to make the charcoal machine. The quality of the screw shaft is related to the stable production of the whole charcoal machine. Therefore, the screw shaft of the charcoal machine must have the following characteristics in order to keep the stable and good operation of the charcoal machine. Charcoal machine is a kind of equipment for making charcoal, which is characterized by that the charcoal machine is crushed into 10 mm particles through a chip grinder, dried and shaped by a dryer, and then put into a carbonization furnace for carbonization. The charcoal produced by this machine has the advantages of high density, small volume and good combustibility, which can replace firewood and coal. This product is especially suitable for heating in autumn and winter, and heating in greenhouse or ordinary domestic fuel. The whole set of charcoal machine consists of rod making machine, carbonization furnace, dryer and other equipment
The screw shaft first has high strength. Due to the comprehensive effect of compression, torsion and bending, especially when the material ring knot or metal and other hard objects are stuck on the screw shaft, if the power can not be cut off immediately, the screw shaft will produce huge stress, so it is required that the screw shaft should have high strength.
The screw shaft also has high wear resistance. The friction between the working material and the surface of the screw shaft, especially the head of the screw shaft, can produce great friction resistance. The screw shaft must have strong wear resistance, which requires improving the compactness and surface hardness of the material. If the surface hardness reaches Vickers hardness, the wear resistance of the spiral shaft will be greatly improved.
The screw shaft also has high heat resistance. When the screw shaft works, in order to make loose materials condense and form, the material temperature is usually kept between 140 ℃ and 160 ℃. Therefore, when the working temperature is not lower than 300 ℃, the mechanical properties of the spiral shaft material are required to remain unchanged, that is, to maintain high strength and hardness.
