There are many types of screw conveyors with significant structural differences and numerous design parameters, which are highly interrelated, making the task of design and selection quite challenging. This is especially true for key parameters such as speed, pitch, and diameter of the spiral blades, as improper selection can severely reduce the production efficiency and operational performance of the screw conveyors. With the development of the national economy, there is an increasing demand for higher conveying capacity and energy-saving in screw conveyors. How to enhance product design, shorten the product lifecycle, and upgrade existing products has become an urgent priority.

Spiral conveyors offer advantages over other types of conveying equipment, such as simple structure, small cross-sectional dimensions, excellent sealing performance, multiple mid-point loading and unloading capabilities, stable and convenient operation, and low manufacturing costs. Due to their high overall stability, long lifespan, adaptability, easy installation and maintenance, spiral conveyors have been widely applied.
