Stainless Steel Screw Conveyor for Material Feed Solution

Product introduction of Stainless Steel Screw Conveyor

The stainless steel screw conveyor is an efficient bulk material handling system designed for continuous transportation of powder, granule, sludge, grain, fertilizer, ash, sand, and small bulk materials. Using a rotating spiral screw inside an enclosed U-shaped or tubular casing, the conveyor delivers stable and automated material transfer with low maintenance and reduced material leakage. Compared with traditional manual feeding systems, it improves production efficiency, lowers labor costs, and supports horizontal or inclined conveying applications. The shaftless screw structure is especially suitable for sticky and wet materials requiring smooth conveying performance. Widely used in food processing, cement production, chemical plants, mining, wastewater treatment, and industrial automation systems worldwide.

Working principle

• Bulk materials enter the conveyor through the feeding hopper or automatic feeding system.
• The motor and reducer drive the spiral screw continuously inside the conveyor casing.
• The rotating screw blade pushes materials forward along the conveying channel.
• Materials move continuously through horizontal or inclined conveyor sections.
• The enclosed conveyor structure minimizes dust leakage during operation.
• Bulk materials discharge smoothly through square or round outlet ports.
• The conveyor system operates continuously for automated industrial material handling.
