What are the requirements for the selection of external structural materials for slag dryers?

Slag dryers are equipment specially used for slag drying. They evaporate the moisture in slag through heating, ventilation and other processes to achieve a certain degree of dryness. Its structure includes components such as heating devices, drums, and hot air flow conduction systems. Slag dryers are widely used in mining, chemical and other fields. They have the characteristics of high drying efficiency and easy operation, which are of great significance to improving slag utilization and product quality. So how should the external structural materials of slag dryers be selected?

1. High temperature resistant materials. Since the temperature of slag dryers is high during operation, the external structural materials need to have good high temperature resistance and be able to work stably for a long time.

2. Corrosion resistant materials. Considering that the slag dryer may be exposed to some corrosive media or gases, the external structural materials should have good corrosion resistance to extend the service life of the equipment.

3. High mechanical strength. The external structural materials need to have high mechanical strength and rigidity to withstand the weight of the equipment itself and possible vibrations and shocks.

4. Wear resistance. The external structural material should have a certain wear resistance and be able to resist the wear and damage that may occur during long-term use.

5. Insulation performance. Considering the high temperature conditions when the slag dryer is working, the external structural material should have good insulation performance to prevent the heat conduction from causing the temperature of the equipment shell to be too high.
