1km 1.25 Rn/S Air Supported Belt Conveyor

• The figure shows the structure diagram for mixed type air supported belt conveyor. The rubber belt (1) runs around the drive pulley (2) and the bend pulley (3), thereby the material is transported from the feeding hopper (5) to the silo. A set of specially designed closed long air boxes with good sealing performance along longitudinal direction of conveyor, commonly known as air chambers. The upper part of air chambers (7) is formed into a disk groove shape (the arc’s radius is R, groove angle is θ), which is called plate trough (6). The rubber belt is supported by the "air cushion" on the groove and driven by drive pulley (2), continuous operation, the empty load branch is still supported by flat lower roller, which is called mixed type air supported belt conveyor.
  A medium-pressure fan (8) is used to blow air into the air box through air inlet, the air flows longitudinally along the air box, filling the air box to form a certain pressure. And through the rows of orifices on the plate trough (6) overflowing into the groove between slots to form a stable "air cushion" support rubber belt and materials, and have the air cushion stiffness of the corresponding pressure to adapt to the load change, changing solid rolling friction of the original roller belt conveyor, significantly reduces the frictional resistance. At the same time, it overcomes the weakness of original roller belt conveyor’s wave operation, the operation is stable and reliable, energy saving effect is also remarkable, thus safety and reliability are greatly improved.

The advantages of ASBC versus conventional conveyors
It is designed to convey free flowing dry products in all types of industries, especially in applications where dust containment is crucial. Its smooth transport and constant air flow means materials stay on the conveyor belt and dusting is practically eliminated.
1. Small power, low energy consumption, reduce the friction between conveyor belt and conveyor idler, reduced motor power
2. Under the same conditions, the power of the air supported conveyor is the same as the power of operation, no additional power increase.
3. Compared with other belt conveyors, small quantity of conveyor idlers, low maintenance costs, long service life of the belt.
4. Small friction resistance of belt,reduce 10%-20% of driving power consumption
5. Enclosed transportation can avoid flying dust and is environmentally friendly.
6. High productivity
The air supported belt conveyor can form the best material loading section. Compared with the roller belt conveyors, it can be loaded with 5%~15% material, which is suitable for high speed operation (the belt speed of the general roller machine is 1.25 rn/s, and the air supported belt conveyor generally 1.6n ∥ s ~ 2.0 hu / s), can improve the transport capacity without increasing the bandwidth.
7. Optional lightweight rubber belt and extended service life
The air supported belt conveyor has low running resistance and low tension. Lightweight rubber belt can be used. It runs smoothly, does not run off, the tape wears little, the tearing phenomenon rarely occurs, and the service life of the tape is more than doubled.
8. Can be used for large dip arrangement
The air supported belt conveyor has continuous gas support, material runs smoothly, its inclination angle is less than the static friction angle of the material and the conveyor belt. The actual angle of inclination of the air supported belt conveyor can be 18° from the roller machine. Increase to 23°. It can also run safely on the left and right.
