There are many types of screw conveyors, but the general principles are the same, which can be briefly summarized as follows:
1. The structure is relatively simple and the cost is low.
2. Reliable operation and easy maintenance and management.
3. Compact size, small cross-section, small footprint. Easy to enter and exit hatches and carriages during unloading operations at ports.
4. It can realize sealed conveying, which is conducive to conveying materials that are easy to fly, hot and have strong odors, can reduce pollution to the environment and improve the working conditions of port workers.
5. Easy loading and unloading. The horizontal screw conveyor can be loaded and unloaded at any point on its conveying line; the vertical screw conveyor can have excellent reclaiming performance if equipped with a relative screw reclaiming device.
6. It can transport in reverse direction, and can also make one conveyor transport materials in two directions at the same time, that is, toward the center or away from the center.
7. The unit energy consumption is relatively large.
8. The material is easy to be crushed and worn during the transportation process, and the spiral blades and troughs are also seriously worn.
