A pipe conveyor belt differs from a conventional, troughed belt in its design and splicing technology and performs special conveying tasks.
Mining and industrial applications often require relatively large inclines and tight curves to be overcome in tight spaces and at high mass flow rates. The particular features of modern pipe belt con - veyors include: no transfer points, no material spillage along the conveyor route, and tight 3D curves. Pipe belt conveyors save space thanks to their compact design, navigate natural terrain, including steep conveyor angles up to 30°.
Design and properties of the pipe conveyor system
The pipe belt works in accordance with a specific operating principle: at the material feed point the conveyor belt is troughed and is fed at this point like a conventional conveyor belt. After the material feed point the conveyor belt is formed into a closed belt pipe by specially configured finger rollers. Further idlers set along the conveyor route guarantee that the belt is kept closed. As a result, the material conveyed remains protected by the closed belt system.
At the end of the belt run the closed belt is opened as a result of the configuration of the finger rollers and adopts a flat shape at the pulley. The material conveyed can then be discharged in the same way as with conventional belt systems.
Pipe Conveyor Belt – product range
Depending on requirements, the pipe belt is equipped with high-quality fabric or steel-cord strength members and a system of transverse reinforcement. This ensures a stable, durable tubular form. The high-tensile steel-cord pipe belts (kN > 5400 N/mm) offer new prospects, for example in surface and underground mining operations.
