Slag dryers use high-temperature hot air to quickly and effectively evaporate the water in slag. How to improve the evaporation rate of water in slag dryers?
1. Hot air temperature. Increasing the hot air temperature helps to accelerate the evaporation rate of water in slag. However, it is necessary to control the temperature to prevent excessive temperature from causing material quality reduction or equipment loss.
2. Initial moisture content of slag. The higher the initial moisture content, the slower the moisture evaporation rate. Therefore, when designing the drying process, the initial moisture content of slag needs to be considered.
3. Structural design of the dryer. The structural design of the slag dryer, especially the shape and size of the drying drum, will affect the residence time and heating uniformity of the slag during the drying process, thereby affecting the moisture evaporation rate.
4. Drying medium selection. Different drying media (hot air, flue gas, etc.) have different evaporation rates for water. Selecting the appropriate drying medium helps to improve production efficiency.
5. Drying time. Ensure that the slag stays in the dryer for an appropriate time to allow sufficient moisture evaporation.
6. Working parameters of the dryer. By adjusting parameters such as the rotation speed and feed speed of the slag dryer, the water evaporation rate can be controlled to a certain extent.
