A screw conveyor is a continuous conveying device that uses rotating helical blades to push materials along the housing. It features a simple structure, good sealing performance, and flexible conveying capabilities, making it particularly suitable for enclosed conveying to prevent material scattering or leakage. It is an indispensable key equipment in material handling systems across various industries and is widely used in food, pharmaceuticals, chemicals, lithium battery, and other sectors.

The screw conveyor operates by a driving device that rotates the screw shaft and blades. Utilizing the friction and thrust between the blades and the material, along with the material’s own gravity and friction with the inner wall of the housing, the material moves forward along the housing as the blades rotate. The conveying direction is determined by the blade rotation direction and the shaft’s rotation direction. For inclined conveying, a larger pitch and higher rotational speed are required to overcome the gravitational component of the material, enabling continuous conveying in both horizontal and inclined directions. With its compact structure and sealed housing, it is suitable for powders, granules, and small lump materials, reducing dust generation or leakage.
