Overview of the screw conveyor screw conveyor in accordance JB/T679-95 "Screw" design and manufacturing standards, is GX type screw conveyor replacement. Auger screw conveyor commonly known, is a mineral, feed, grain and oil, construction the use of a broader transportation equipment, transportation of materials from the perspective of the direction of displacement of the division, screw conveyor is divided into horizontal and vertical screw conveyor screw conveyor into two types, mainly used for all kinds of powder, granular and horizontal transport of small lumps and other loose materials and vertical lifting. screw conveyor screw conveyor range of applications in industrial and agricultural sectors are the main units of mechanized transportation to work, make transportation work to reduce labor intensity and improve working efficiency, range of applications wide. applicable to all industries, such as building materials, chemicals, electric power, metallurgy, coal, grain and other industries, for horizontal or inclined conveying powder, granular and small bulk materials such as coal, ash, slag, cement, food, etc. material temperature less than 200 ℃. spiral machine suitable for transporting perishable, viscous, easy caking materials main features of a screw conveyor. carrying capacity, safe and reliable 2. adaptable, easy installation and maintenance, long life 3. machine small, high speed, to ensure rapid and uniform delivery 4. discharge end with a cleaning device, a low-noise machine, adaptable, flexible arrangement of material inlet and outlet location. 5. better sealing, The shell is made of seamless steel pipe production, the end flange integrally connected to each other, and good rigidity. screw conveyor screw conveyor working principle is to use the rotating spiral within the material is transported along the stationary case goes conveyed work Move to the head and tail bearing housing, the crane has a dust-bearing sliding bearing seals, bearings generally use powder metallurgy, transport cement using blankets bearing, shaft and screw shaft with hanging sliders connection.
