By the drive device to close the tank box and helix composed of spiral rotation of the tank to push the coal output.
Screw conveyor is characterized by: simple structure, small cross-sectional size, good sealing, reliable, low manufacturing cost, easy to load and unload the middle, the direction of transport can be reversed, but also to the opposite direction of the two transport. During the course of transportation, the materials can be stirred, mixed, heated and cooled. Through the loading and unloading gate can adjust the material flow. But not easy to transport perishable, sticky, easy to caking and large pieces of material. The material is easy to be broken in the conveying process, the screw and the trough are easy to wear. Unit power larger. In use to keep the trough sealing and screw and the trough with appropriate clearance.    
Vertical screw conveyor for short-distance vertical transport. Flexible screw conveyor screw by the flexible shaft and synthetic rubber blades, easy to bend, according to site or process requirements arbitrary layout, the space transport. Screw conveyor blades are pull-and pull the whole pull, now pull can be made of any thickness and size, the whole pull-type should not be made of non-standard spiral.
From the perspective of the direction of material displacement, the screw conveyor is divided into horizontal type screw conveyor and vertical type screw conveyor. It is mainly used for horizontal conveying of various loose materials such as powder, granule and small block. And vertical lifting, the screw conveyor is not suitable for conveying the perishable, sticky, easy to caking or high temperature, fear of pressure, a greater corrosive special materials.
Screw conveyor generally consists of the conveyor body, inlet and outlet and drive the three major components; screw conveyor spiral spiral surface of the entity, the belt-type spiral surface and the spiral surface of the three forms, of which the blade-type spiral surface application Relatively small, mainly used for conveying large viscosity and compressibility of materials, this spiral suspension type, in the completion of the delivery process, both with and complete the mixing of materials, mixing and other functions.
Compared with other conveying equipment, the screw conveyor has the advantages of small size, good sealing performance, stable and reliable running, multi-point loading and unloading in the middle, safe operation and easy maintenance.
