The Screw Feeder Conveyor is a mechanical device designed to transport materials through a rotating helical screw. These systems are widely used in various industries for the efficient and controlled feeding of bulk materials into processing or packaging machines. Known for their simplicity, durability, and versatility, screw feeders are commonly employed in industries such as agriculture, chemicals, food processing, plastics, and pharmaceuticals.
Unlike traditional conveyor systems that rely on belts or rollers, the screw feeder conveyor uses a rotating screw element to move materials. This method of transport allows for continuous, consistent, and precise movement of materials, making it an ideal solution for applications where accurate dosing and controlled flow are necessary. Whether transporting powders, granules, or even liquids, the screw feeder conveyor can handle a wide variety of materials with ease.
![]() | Precise Material Feeding and Flow ControlOne of the standout features of the Screw Feeder Conveyor is its ability to provide precise material feeding. The screw element, which is typically housed within a tube or trough, rotates to push the material forward. This process ensures a steady and uniform flow of materials, which is essential for operations that require accurate and consistent dosing. By adjusting the screw’s rotational speed, operators can easily control the flow rate, providing flexibility in material handling. |
![]() | Versatility in Material HandlingThe Screw Feeder Conveyor is incredibly versatile and can handle a wide range of materials, from granular solids to powders and even slurries.

Screw feeder conveyor machine is mainly composed of the following parts: 1. Spiral shaft: It is the core part of the spiral feeding machine, which is driven by the motor to rotate and drive the spiral blade to rotate. 2. Spiral blade: fixed on the spiral shaft, used to push the material forward. 3. Shell: the spiral shaft and spiral blade are installed in the shell, and the shell protects the spiral shaft and spiral blade from the interference of the external environment. 4. Feed port: used to add the material into the spiral groove. 5. Discharge port: The material is finally discharged from the discharge port through the push of the spiral shaft and spiral blade. 6. Transmission device: including motor, reducer, coupling, etc., used to drive spiral shaft rotation. |
4 | Work phase |
The working process of the Screw feeder conveyor machine can be divided into the following stages: 1. Feeding stage: The material enters the spiral groove through the feeding port. 2. Conveying stage: the motor drives the spiral shaft to rotate, and the spiral blade pushes the material into the spiral groove and moves forward along the spiral shaft. 3. Discharge stage: the material is finally discharged from the discharge port under the push of the spiral blade. |
