Ceramic Spiral has the following characteristics
1) Easy loading and unloading. The horizontal screw conveyor can be loaded and unloaded at any point on its conveying line; The configuration of a vertical spiral conveyor with a relatively spiral material retrieval device can have excellent material retrieval performance.
2) It can be used for reverse conveying or for a conveyor to simultaneously transport materials in two directions, either towards the center or away from the center.
3) The unit energy consumption is relatively high.
4) Materials are prone to crushing and wear during transportation, and the wear of spiral blades and material troughs is also quite severe.
