The main body of the screw conveyor consists of three sections: the head section, the intermediate section, and the tail section. Typically, during final assembly at the factory, the intermediate sections are arranged in order of length—starting with the longest one placed closest to the head section, while intermediate sections of equal length are positioned next to each other. Inside the head section, a thrust bearing is installed to handle axial forces, while the intermediate and tail sections house support bearings that hold the helical shaft in place. Additionally, the tail section includes a radially adjustable bearing capable of axial movement, designed to compensate for any inaccuracies in the helical shaft’s length and accommodate thermal expansion or contraction. The helical flights come in two types: solid (S-type) and belt-type (D-type). The individual helical shafts are connected using flanged joints, ensuring interchangeability of the connecting shafts and simplifying maintenance.

Inside the head section, a thrust bearing is installed to handle axial forces, while the intermediate and tail sections house rolling bearings that support the helical shaft. Additionally, the tail section includes a radial bearing designed for axial movement, which helps compensate for any inaccuracies in the helical shaft’s length and accommodates thermal expansion or contraction. The helical flights come in two types: solid-flight screws (S-type) and belt-flight screws (D-type). The individual helical shafts are connected using flanged joints, ensuring interchangeability of the connecting shafts and simplifying maintenance.

The screw conveyor can be used to transport materials in any situation where spiral conveyance is suitable—whether the material is moving horizontally, at an incline, or vertically—in a continuous manner. Notably, when conveying materials at an incline or vertically, the screw conveyor can be directly connected and securely mounted to its accompanying equipment, eliminating the need for a separate foundation and making efficient use of available space.

 

The screw conveyor features excellent sealing, eliminating dust and pollution leaks—ensuring no material waste while simultaneously creating a clean and healthy working environment. With its small-diameter helix, high rotational speed, and large conveying capacity, this type of conveyor is particularly well-suited for inclined and vertical material transport.

A Guide to the Standard Conveyor Angle Range for Screw Conveyors

A Guide to the Standard Conveyor Angle Range for Screw Conveyors

The tilt installation angle of a screw conveyor directly affects its conveying capacity, equipment failure rate, and overall service life. Different designs—whether with or without a shaft, U‑shaped or tubular—and materials with varying physical properties require significantly different standard tilt angles. In many production lines, improper tilt‑angle design leads to persistent issues such as material backflow, blockages, blade deformation, and motor overload. This paper systematically reviews the standard conveying‑angle ranges for all types of screw conveyors, along with material‑compatibility guidelines and optimized solutions for steep inclines, providing a standardized reference for equipment procurement and on‑site retrofitting.
