tubular belt conveyor
performance features
Tubular belt conveyors in addition to ordinary belt conveyor performance characteristics, also has its own more prominent　　

1) transport a variety of materials

Currently tubular belt conveyor has been widely used in iron and steel, building materials, ceramics, paper, food, salt and chemical industries in abroad.

2) closeness transfer materials

Due to materials is running surrounded by a tubular tape, so the material will not be scattered and flying, will not affected by the external environment such as blowing wind, rain. It can reduce material environmental pollution especially in the transport of materials such as slag, ores.

3) transport lines can be arranged along the space curve

Due to the formation of tubular tape, when it runs，each part of the tape can be crooked . For nylon canvas tape, within its horizontal and vertical plane，the minimum radius of curvature can be reduced to 300 times of the pipe diameter.

4) large inclination transport

Since the tape is circular tubular ，increased the friction coefficient between the material and the tape, and therefore the maximum inclination angle of the lines is up to 30 °. If the tape vulcanizes certain pattern and Bump Taiwan, inclination up to 40 °Its inclination for the poor mobility of materials can also be increased. This feature is very important for transporting materials to top places occasions. Because it can reduce the feed length, the space-saving position, it reduces equipment costs.

5)respectively use the tape upper and lower branches convey materials back and forth

As load (on) branch and no-load (bottom) branches tape are tube-shaped, so it can be under the (no-load) branch conveying materials in the opposite direction， but need to set up a special feeding device.
According to the above performance characteristics, the advantages of tubular belt conveyor can be summarized as follows: (1) reduce the material transport losses; (2) does not pollute the environment during transportation; (3) low cost of manufacturing and installation (compared to ordinary belt conveyor with the plus cover); (4) the arrangement is flexible, especially suitable for complex terrain and obstacles environment; (5) Compact structure， small cross-section small to save space; (6) long distance transport (stand-alone up to 3000 meters); (7) large volume (up to 7000 tons per hour traffic); (8) can use an ordinary roller, belt running deviation phenomenon does not occur which not like the common belt conveyor.
Due to tubular belt conveyor with the above characteristics, it gradually be promoted and adopted in mines, power plants, ports, iron and steel, chemicals, building materials and other industries. It is the development direction of the international and domestic belt conveyors.
