7 t/h Flexible Screw Conveyor for Grain Transfer with Hopper

Product introduction of Flexible Screw Conveyor

The flexible screw conveyor is an industrial material handling machine designed to transport powders, granules, and solid mixtures in inclined or horizontal orientations. Constructed from food-grade stainless steel, it prevents contamination and is easy to clean, making it ideal for food, pharmaceutical, chemical, and feed industries. The device solves challenges of moving bulk materials efficiently, allowing continuous, controlled transport from one process to another. Widely used in mixers, ovens, vats, and production lines, it improves operational efficiency while maintaining hygiene and safety standards across agricultural, chemical, and industrial applications.

Working Principle

The flexible screw conveyor operates using a rotating spiral screw inside a trough. As the screw rotates, it pushes powders, granules, or solid mixtures along the trough in a controlled, continuous flow. The incline allows material to move upward or downward, depending on installation, while the smooth stainless steel surface ensures minimal friction, reduced contamination risk, and easy cleaning. It is ideal for handling sterile, bulk, or granular materials in industrial food, pharmaceutical, chemical, and feed processing applications.
