The U-type screw conveyor (also known as trough screw conveyor), with its unique U-shaped trough design, is the preferred equipment for conveying bulk and sticky materials. It is suitable for horizontal or small-angle conveying of powders, granules, and small lump materials, and is widely used in grain, chemical, building materials, metallurgy, mining, electric power, and other industries.
The core advantages of the U-type screw conveyor are reflected in the following aspects:
Adaptability to various working conditions: During conveying, materials can simultaneously undergo mixing, blending, heating, and cooling. The equipment allows loading and unloading at any point on the conveying line, supporting intermediate and multi-point feeding.
Convenient maintenance design: The upper part is equipped with inspection covers, making it easy to clean, maintain, and debug in case of blockage or material entanglement.
Flexible material options: Depending on the material being conveyed, carbon steel (economical) or stainless steel (corrosion-resistant and hygienic) can be chosen.
Rich specification range: Spiral diameters range from 150 mm to 600 mm in 7 sizes, and conveying lengths can be freely selected from 3 m to 30 m.
Flexible installation angle: Installation inclination up to 0-25°, with conveying capacity up to 134 m³/h.
The U-type screw conveyor is available in both shafted and shaftless versions – the shafted type is suitable for conventional powders and granules, while the shaftless type is specially designed for easily entangled and highly sticky materials.
