Screw conveyor belt is a friction drive for material transport in a continuous manner machinery. Application of the material which can be given in a belt conveyor conveying line, from the initial feed point to the discharge point is formed between the final delivery process a material. It can deliver a granular material, can also be transported into pieces items. In addition to the pure material handling, but also with the requirements of various industrial processes in the production process of the match, the formation of the rhythmic flow transport line. So all kinds of belt conveyor is widely used in modern industrial enterprise. In the mine underground tunnel, mine ground transportation systems, open pit and concentrator, widely used conveyor. It is used for horizontal or inclined transportation transport. Very easy to use. Main features: 1. load capacity, safe and reliable. 2. adaptable, easy installation and maintenance, long life. 3. The whole small, high speed, to ensure rapid and uniform delivery. The cleaning device has a discharge end, low-noise and adaptable, flexible layout expected out of position. 5. tightness, and the shell is made of seamless steel pipe production, the end flange integrally connected to each other, and good rigidity.
