Types of Screw Conveyors

Vertical (Incline) Screw Conveyors

Incline screw conveyors, also known as Vertical Screw conveyors, are designed to move materials at an angle. These conveyors are particularly useful when dealing with materials that need to be elevated or lowered. They find applications in industries such as Agriculture, Mining, and Construction, where the need for vertical transportation arises.

Horizontal Screw Conveyors

The most common type of screw conveyor, horizontal screw conveyors, operate horizontally, moving materials from one point to another. These conveyors are widely used in industries such as Food Processing, Agriculture, and Manufacturing. They are versatile and can handle a variety of materials, making them a popular choice for bulk material handling.

Flexible Screw Conveyors

Flexible screw conveyors, also known as spiral conveyors, are characterised by a flexible yet sturdy helical screw enclosed in a tube. These conveyors are highly adaptable and can transport materials around corners and in tight spaces. The flexibility of the screw allows for efficient conveying of materials without spillage, making them suitable for applications in the pharmaceutical, chemical, and food industries.

Shaftless Screw Conveyors

Shaftless screw conveyors are designed without a central shaft, allowing for the conveyance of larger and irregularly shaped materials. This design minimises the risk of clogging and facilitates easy handling of sticky and viscous materials. Industries such as Wastewater Treatment, Pulp and Paper, and Municipal Solid Waste Management often benefit from the use of shaftless screw conveyors.

Tubular Screw Conveyors

Tubular screw conveyors consist of a tube through which a helical screw rotates, moving materials along the axis. This design is effective for preventing material contamination and spillage. Tubular screw conveyors are commonly used in industries such as Pharmaceuticals, Chemicals, and Plastics, where maintaining product integrity is crucial.

U-Trough Screw Conveyors

U-trough screw conveyors are characterised by their U-shaped trough, which houses the helical screw. This design is ideal for handling abrasive or corrosive materials, as it provides protection and containment. U-trough screw conveyors are commonly employed in industries like Mining, Cement, and Agriculture.

Screw conveyors play a vital role in numerous industries by facilitating the efficient movement of bulk materials. Understanding the different types of screw conveyors and their specific applications is crucial for selecting the right conveyor system to meet the unique needs of a given industry. Whether it’s incline, horizontal, flexible, shaftless, tubular, or U-trough screw conveyors, each type offers distinct advantages, making them suitable for various material handling challenges. When designing a material handling system, careful consideration of the type of screw conveyor is essential to ensure optimal performance and productivity.
