Coal mining scraper conveyor can be used for horizontal and low-inclined material conveyance, while vertical screw conveyor can be used for short distance vertical conveyance.
The outer layer of the conveyor is a metal chute, and the inside is a main shaft and a spiral blade. It has the advantages of simple and compact structure and small cross-sectional size. The manufacturing process of the conveyor is mature, the price is low, and the one-time investment is small. The conveying mode of the scraper conveyor can be adapted to any point and multi-point unloading and loading, the conveying direction can also be arbitrarily changed, and it can realize the simultaneous conveyance of materials in two directions. In the process of conveying the material, it is accompanied by the process of stirring and mixing the material, and can cooperate with heating or cooling operations.
The maximum temperature of the coal mining scraper conveyor can not exceed 200 ° C, and the inclination angle does not exceed 20 °. The screw conveyor has the function of stirring and mixing in the conveying process. It cannot be used for the transportation of easily-adhesive, easily-deteriorated and fragile materials, especially the fragile materials will be broken during the conveying process and damage the spiral and the trough.
