Trough Screw Conveyor

The trough screw conveyor is a widely used conveying device in various industries, known for its simple structure and high conveying efficiency. It operates on the principle of spiral conveying, utilizing rotating spiral blades to push materials forward along a closed trough, which prevents material spillage and environmental contamination. The design of the spiral blades can be customized based on the characteristics of different materials, allowing for versatile applications.

Characteristics and Advantages

Wide Applicability: Capable of transporting a variety of bulk, powdered, and small particle materials, suitable for horizontal, inclined, and vertical conveying.

Simple Structure: The straightforward design results in low maintenance costs and ease of cleaning.

High Transport Efficiency: Adjustable parameters such as spiral blade diameter, pitch, and speed enhance efficiency to meet different material transport requirements.

Long Transport Distances: Designed for varying lengths, these conveyors can transport materials over distances from several meters to dozens of meters.

Integrated Transport and Weighing: High-precision weighing sensors can be embedded within the conveyor for automated production processes.

Application Scenarios

Trough screw conveyors are utilized across various industries, including:

Chemical Industry: Transporting bulk materials like cement, lime, and iron powder.

Food Processing: Conveying powdered materials such as sugar, salt, and starch.

Pharmaceutical Industry: Moving various pharmaceutical raw materials.

Mining Operations: Suitable for transporting granular materials like ores, coal, and grains.

Construction Sites: Used for conveying materials such as concrete and mortar.
