The mandrel of the machine is flexible, so the transmission line can be arranged according to the space curve. According to the different length ratio of horizontal and vertical (large inclination) section in the layout line, the working principle is designed according to ordinary screw conveyor or vertical screw conveyor.
For the transmission line needs to be arranged according to the spatial curve arbitrarily, avoids the material reprint the occasion, when the machine shell enters the excessive material or has the hard block material, the Helix realizes the free float, does not produce the card plugging phenomenon; the noise is small. It is mainly used to complete the horizontal and vertical conveying of the material at the same time. Vertical conveying generally requires a high speed should not be lower than 1000r/min.
