Pipe conveyor belts represent a specialized form of bulk material handling system designed to transport materials in a closed tube configuration. This innovative design minimizes spillage and environmental impact, allowing for both horizontal and vertical curves without the necessity of transfer points. The closed design means that materials are fully enclosed within the belt, making it ideal for transporting fine powders, granules, and other bulk materials that may otherwise spill, creating a hazard or contamination issue.
The construction of a pipe conveyor belt involves six hexagonal idlers that help the belt maintain its tubular shape during operation. The flexibility of the belt is crucial, as it must be able to handle the transitions from flat to tubular configurations while maintaining structural integrity and performance. Typical tube diameters range from 150 mm to 600 mm, accommodating various material types and bulk densities.
In terms of material composition, these belts are crafted from high-quality elastomers and reinforced with textiles or steel cords to provide the necessary strength and flexibility. This ensures that the belt can withstand the demands of the transportation process, including load variations and the need for tight curves. Brands such as Continental, Bridgestone, and Phoenix are known for their high-performance pipe conveyor belts, which feature advanced materials and engineering techniques to ensure reliability and efficiency in demanding industrial environments.
