Stainless steel trough screw conveyor
Ideal for precise handling of powdery and granular materials, this solution ensures minimal residue with smooth stainless steel surfaces, optimizing hygiene and efficiency in processing lines where contamination must be strictly avoided.

Conveys and Feeds Powdery and Granular Materials
The Stainless Steel CX Trough Screw Conveyor System from WAMGROUP offers an efficient solution for conveying and feeding a variety of powdery and granular materials across multiple industries. Featuring a modular design, this system uses a U or V-shaped trough with helicoid screw flighting to ensure continuous and smooth material movement. It’s particularly suitable for applications where contamination must be avoided, such as in food, chemical, and pharmaceutical productions. The conveyor’s stainless steel construction ensures high resistance to corrosion, making it ideal for handling sensitive materials like flour, coffee, and pharmaceuticals.
Engineered to handle diverse end-products from protein powder to instant coffee, the system maintains ISO compliant cleanliness and reduces residue with perfectly smooth troughs. Modular lengths and customization options, including ATEX Zone 22 certification, allow seamless integration into existing production lines. The gear motor setup enhances energy efficiency, while bearing assemblies ensure a balanced operation, reducing maintenance downtime. Optional features like intermediate hanger bearings and inspection hatches further boost operational flexibility.
