Compared with traditional belt conveyor, the biggest feature of round pipe belt conveyor is that conveying belt can be curled into round pipe shape in the running process, to realize closed conveying to material. Its working principle is: conveying belt is unfolded into plane at head and tail, to facilitate the loading and unloading of material;In the middle section, conveying belt is gradually curled into round pipe shape by special roller group, completely wraps material in pipe, avoids material spilling and environmental pollution. This design not only reduces the loss of material in the conveying process, but also effectively prevents dust overflow, especially suitable for conveying material that is easy to dust, easy to volatilize or sensitive to environment. In addition, round pipe belt conveyor also has the advantages of flexible conveying line, adapting to complex terrain, saving space etc. Its conveying line can be arranged horizontally, vertically or at any angle, adapts to various complex terrain conditions, reduces the amount of civil engineering and equipment investment. At the same time, since the conveying belt is curled into round pipe shape, the cross section of the conveyor is small, which saves space, especially suitable for occasions with limited space.
