Pipe spiral conveyor is a continuous conveying equipment that uses spiral rotation to push materials, suitable for conveying materials such as flour, grains, cement, fertilizers, ash, sand, stones, coal powder, small pieces of coal, etc. Due to the small effective circulation area inside the body, screw conveyors are not suitable for conveying materials that are prone to spoilage, have high viscosity, and are prone to clumping. The tubular screw conveyor can be arranged in a horizontal or inclined conveying form. If the tubular screw conveyor needs to change direction for conveying, special orders should be made.

Spiral conveyors are widely used in various industrial sectors, such as building materials, power, chemical, metallurgical, coal, aluminum magnesium, machinery, light industry, grain and food industries; Suitable for horizontal or less than 20 °, tilt angle. Spiral conveyors have a simple structure, low manufacturing cost, strong sealing, and discharge capability. The machine has advantages such as easy operation, multiple installation points in the middle, no need to move the driving device, no need to move the screw when disassembling the suspension bearing, no need to disassemble the cover plate to lubricate the suspension bearing, high reliability, long service life, strong adaptability, and easy installation and maintenance. Spiral conveyors should not handle materials that are prone to deterioration, high viscosity, or clumping. These materials will adhere to the screw during transportation and rotate without moving forward, or form material blockages at the suspension bearings, which will prevent the spiral conveyor from working properly. The spiral diameter ranges from 200 millimeters to 500 millimeters, with a total of five specifications and lengths ranging from 4 meters to 70 meters, with intervals of 0.5 meters. The selection is based on the standard nominal length, and special requirements can be separately stated in the optional section.
