What is a Twin Screw Conveyor?

A twin screw conveyor is a type of screw conveyor with two parallel helical screws used to transport materials from one point to another.

Compared to traditional single screw conveyors, twin screw conveyors provide higher efficiency and better handling of special materials, including those with high moisture, that tend to clump, or are sticky.

Applications of Twin Screw Conveyor

For industries:

• Food processing: For mixing and transporting powdery or granular ingredients.

• Chemical industry: For conveying and mixing powdered or granular chemicals.

• Waste treatment: For transporting solid or semi-solid waste.

• Fertilizer production: For mixing and conveying raw materials.

• Transporting sawdust.

For materials:

• Transporting bulk materials at high capacity and speed.

• Conveying high-viscosity or sticky materials.

• Moving materials that require mixing during conveying.

• Lifting materials vertically.

Key Features of Twin Screw Conveyor

Twin screw conveyors offer several outstanding advantages, such as:

• High efficiency: Excellent material handling, especially for difficult-to-convey materials.

• Mixing capability: Better mixing of materials during conveying.

• High capacity: Double the capacity compared to a single screw conveyor.

• Time and energy savings.

• High durability: Strong structure, less prone to damage.

• Easy to clean: Can be easily disassembled.

Basic Structure of Twin Screw Conveyor

Here is an overview of the main components of a twin screw conveyor:

• Trough: The outer casing that holds materials, designed to accommodate two parallel screw shafts.

• Screw Shafts (Helical Screws): Two synchronized parallel screws that push the material along the conveyor.

• Gearbox and Motor: Provide the necessary power to rotate the screws.

• Inlet and Outlet: The inlet is where material enters, and the outlet is where it exits.

• Cover: In some applications, a cover is installed to prevent spillage.
