The spiral conveyor has the following characteristics:
1) The relatively simple structure and the low cost.
2) Reliable work, easy maintenance and management.
3) Compact size, small section size and small footprint. It is easy to enter and exit hatches and carriages during unloading and unloading operations in ports.
4) It can realize sealed transportation, which is conducive to the transportation of easy-to-fly, hot and strong-smelling materials, which can reduce the pollution to the environment and improve the working conditions of port workers.
5) Easy to load and unload. The horizontal spiral conveyor can be loaded and unloaded at any point on its conveying line; the configuration of the vertical spiral conveyor can have excellent reclaiming performance compared to the spiral reclaiming device.
6) It can be conveyed in the reverse direction, and a conveyor can also convey materials in two directions at the same time, that is, to the center or away from the center.
7) The unit energy consumption is large.
8）The material is easy to be crushed and worn during the conveying process, and the wear of the spiral blade and the trough is also serious.
