GL Series Tubular Screw Conveyor for Cement, Fly Ash & Bulk Powder
(Konveyor Sekrup Tabung Seri GL untuk Semen, Abu Terbang & Bubuk Curah)
Enclosed screw conveyor for efficient powder conveying, dust-proof transport, and continuous feeding
Overview
The GL Series tubular screw conveyor, also known as an enclosed screw conveyor or tube screw conveyor, is designed for efficient and dust-free conveying of bulk powders and granular materials.
Featuring a fully enclosed circular tube structure, this tubular screw conveyor ensures clean operation, prevents material spillage, and minimizes environmental contamination. It is widely used for conveying cement, fly ash, lime powder, grain, sand, sludge, and other bulk materials in continuous and automated handling systems.
The GL Series tubular screw conveyor supports horizontal, inclined, or vertical installation, making it a flexible solution for cement plants, dry mortar production lines, mining facilities, and bulk powder processing systems.
For a detailed explanation of screw conveyor fundamentals, refer to the Wikipedia entry on screw conveyors.

FAQS About Tubular Screw Conveyors
Q1: What is a tubular screw conveyor used for?
A: A tubular screw conveyor is used for enclosed conveying of bulk powders and granular materials, such as cement, fly ash, lime powder, grain, and industrial residues. Its enclosed design ensures clean and dust-free operation.
Q2: What is the difference between a tubular screw conveyor and a U-type screw conveyor?
A: A tubular screw conveyor features a fully enclosed circular tube, providing better dust sealing and environmental protection. U-type screw conveyors are open-top and more suitable for less dusty materials.
Q3: Can a tubular screw conveyor handle cement and fly ash?
A: Yes. Tubular screw conveyors are widely used for cement and fly ash conveying, especially in applications requiring dust control and continuous material flow.
Q4: Is a tubular screw conveyor suitable for inclined or vertical conveying?
A: Yes. Tubular screw conveyors can be installed horizontally, inclined, or vertically depending on layout requirements, although capacity may vary with installation angle.
Q5: How do I choose the right tubular screw conveyor size?
A: Selection depends on material bulk density, required capacity, conveying length, and installation angle. LVRUI engineers can recommend the optimal tubular screw conveyor system based on your application.
