U-Type Screw Conveyor for Powder & Bulk Materials
(Konveyor sekrup tipe U untuk bahan bubuk & curah)
Efficient U-type screw conveyor for reliable bulk powder handling
Overview
The U-Type Screw Conveyor is a widely used bulk material conveying solution designed for the continuous transportation of powder and granular materials. Featuring a U-shaped trough and rotating screw shaft, this system ensures stable material flow with minimal spillage and dust emission.
This U-type screw conveyor for powder handling is commonly applied in cement plants, fly ash processing lines, limestone handling systems, and chemical industries. The open U-trough structure allows for easy inspection, cleaning, and maintenance, making it especially suitable for materials that require frequent monitoring.
Compared with enclosed tubular conveyors, the U-shaped screw conveyor offers higher adaptability for short- to medium-distance conveying and can be integrated with feeders, hoppers, and silos. It supports horizontal conveying as well as inclined conveying up to 20°, ensuring flexible layout design for industrial production lines.
Manufactured with wear-resistant materials and precision machining, LVRUI U-type screw conveyors deliver reliable performance, long service life, and stable operation in demanding industrial environments.

FAQS About U-Type Screw Conveyor
What materials can a U-type screw conveyor handle?
A U-type screw conveyor is suitable for dry powder and granular materials such as cement, fly ash, limestone powder, coal ash, and chemical powders. It is not recommended for sticky or highly wet materials unless specially designed.
What is the difference between a U-type and tubular screw conveyor?
A U-type screw conveyor features an open trough structure, allowing easier inspection and maintenance, while a tubular screw conveyor is fully enclosed and better suited for dust-sensitive environments.
Can the U-type screw conveyor be customized?
Yes. LVRUI provides customized U-type screw conveyor solutions, including screw diameter, length, motor power, material selection, and sealing options based on project requirements.
What is the maximum conveying angle?
Standard U-type screw conveyors can operate horizontally or at an inclined angle up to approximately 20°, depending on material characteristics.
