What is a pipe conveyor
Pipe conveyor, also called tubular conveyor, is a kind of conveying equipment that uses traditional grooved rubber belts to make pipes for material handling. It realizes the tubular structure by increasing the excessive idler angle and finally a roller set composed of six idlers on the specified diameter. The diameter and spacing of the roller set are determined by the size of the pipe conveyor and the material being transported.
The pipe conveyor system can be used to transport all types of bulk or powder materials from fine grains to 700 mm block sizes. It is commonly used to transport coal, ore, fly ash, cement, quicklime, blast furnace dust, petroleum coke and other materials.
Depending on the application, the pipe belt is made of high-strength steel cords or textile reinforced materials, and provides various coverage levels.
Pipe conveyor advantages
- The pipe conveyor is a closed long-distance trough conveyor system, which can avoid possible dust pollution and material spillage during transportation and help protect the environment.
- It can protect the transported materials from external conditions such as snow, rain, wind and dust.
- The pipe conveyor can pass through steep slopes up to 30 degrees and can cover terrain that is difficult for traditional conveyors to pass.
- Equipment maintenance and operating costs are low.
The difference between pipe conveyor and belt conveyor
The pipe conveyor is similar to the traditional belt conveyor at the material receiving point and discharge point. Both provide a flat conveyor belt. The flat belt is slowly formed into a trough belt through transition and load-bearing idlers. At a certain distance from the loading point, the conveyor belt gradually becomes a tubular shape with the help of special roller devices (variable off set rollers, finger rollers and pipe forming idlers) within a certain distance. Near the unloading point, the tubular conveyor belt gradually becomes a flat conveyor belt for unloading by taking on the idler.
