The Part That Actually Moves the Material
Cosben Internal Screws are manufactured for Screw Feeders and Screw Conveyors to ensure efficient and reliable bulk material conveying. Each internal screw consists of a continuous flight welded to a centre pipe, providing smooth and consistent material movement.
Depending on the application, internal screws can be manufactured with a variety of flight pitches and anti-wear coating options to suit different material characteristics and operating conditions. A bush coupling at both ends enables seamless connection with hanger bearings and end bearings, ensuring proper alignment and smooth screw rotation.
Available in multiple diameters and lengths, Cosben Internal Screws are designed to be interchangeable and compatible with existing Screw Feeders and Screw Conveyors.
