With the development of modern production, environmental protection has become an increasingly important issue in today's era, and has attracted extensive attention all over the world. The dust and scattered materials produced by the conveying system in the work have caused more and more attention to the environmental pollution by the conveyor design, manufacturing, use and administrative departments all over the world. In order to reduce the pollution in the conveying process and promote environmental protection and pollution-free conveying of materials, people have developed various forms of closed belt conveyors. The characteristics of the closed belt conveyor developed and produced by kunwei machinery are as follows:

1. Airtight conveying of materials

No flying, scattering and leakage. Because the return branch conveyor belt is tubular, there is no need to worry about the scattering of materials adhered to the conveyor belt. At the same time, it also prevents the mixing of materials outside the pipe, realizes harmless transportation and purifies the environment.

2. Space free bending conveying

It can bypass all kinds of obstacles and facilities without multiple reprints. It has convenient design and simple layout. It can design a very economical overall layout scheme to realize spatial bending layout with a small radius of curvature.

3. It can increase the inclination of the conveyor

The materials are wrapped in the conveyor belt, which can increase the mutual friction between the materials and the inner surface of the conveyor belt, so as to improve the inclination of the belt conveyor β ≥ 30 °, 60 ° ~ 90 ° with diaphragm can shorten the length of the whole machine, reduce the cost and capital construction cost.

4. No deviation

According to its structural principle, this kind of conveyor will not deviate, which can reduce the maintenance cost.
