Thermal Heating & Cooling for Screw Conveyors
Thermal Heating & Cooling for Screw Conveyors
High-temperature screw conveyors are designed for use in industries and applications where materials are exposed to high temperatures (typically above 200°C (392°F)), the following are some common applications of high-temperature screw conveyors:
Cement Production: Used to transport hot clinker from one location to another.
Steel production: High temperature screw conveyors are used to transport hot steel or other metal products in steel mills or other metal processing facilities.
Power Generation: Can be used to convey fly ash, bottom ash or other types of ash produced by power plants.
Chemical Handling: Can be used to transfer chemicals exposed to high temperatures, such as molten sulfur or other high temperature liquids.
Food processing: Can be used to convey food exposed to high temperatures during processing, such as roasted coffee beans or baked goods.
Plastic processing: Can be used to convey plastic pellets or other plastic materials exposed to high temperatures during processing.
Glassmaking: Can be used to transport hot glass in glassmaking facilities.
What Is Screw Conveyor
What is a screw conveyor? The screw conveyor is a kind of conveying equipment that is widely applied in the chemical industry, construction industry, and grain industry for transporting powder, granular, and small block materials. Its optimal operating environment temperature is 20~50℃, and the conveying length is generally less than 40m, the longest is not more than 70m, suitable for short-distance materials conveying. Compared with other conveying equipment, it has the advantages of a simple structure, small cross-section size, good sealing performance, safe operation, and low cost. Besides, the screw conveyor can receive materials from one or more points and discharge materials to multiple points, while its conveying capacity is relatively low and the machine parts are easy to wear. In the cement industry, the screw conveyor is indispensable for cement plant equipment. The conveyor produced by AGICO has good rigidity and runs steady, the coaxiality of the helical blade and the helical shaft is high.
Screw Conveyor Design
The screw conveyor is mainly composed of head bearing, end bearing, hanger bearing, feeding port, discharge port, screw, trough, trough cover, drive device, etc.
Types Of Screw Conveyor
The screw conveyor can be divided into the ordinary screw conveyor, tubular screw conveyor, and shaftless screw conveyor。
The ordinary screw conveyor is a conveyor that has a screw shaft. It can be further divided into vertical screw conveyor, inclined screw conveyor, and horizontal screw conveyor.
The shaftless screw conveyor has no shaft and equips a liner inside the trough. It has a simple and sealed structure. For many difficult conveying materials, the shaftless screw conveyor is a better solution.
The outside casing of the tubular screw conveyor is made of a seamless steel tube, which has better tightness and rigidity. Although its body is small, the bearing capacity is large, its adaptability is strong, can ensure the uniform delivery of materials.
