Regarding the operating temperature of screw conveyors
Thread Content
According to the descriptions in relevant materials, \"Screw conveyors are mainly used for transporting powdered and granular materials; they are not suitable for transporting materials with high viscosity or those that tend to clump together.\" Its advantages are good sealing performance, as well as the ability to load and unload from multiple points. Its drawback is severe wear of the components, which can easily cause the material being transported to break. The operating temperature range for screw conveyors is -20 to 50°C, and the temperature of the materials being conveyed should be below 200°C. The question is: why is there a temperature limit on the materials being conveyed, and what are the consequences if the temperature is too high?
Materials expand when heated, reducing the clearance between moving parts; this can cause the materials to deform. Heat conduction may also lead to poorer lubrication in the reducer. Special designs can be used for high-temperature environments!
