The appropriate value of slag drying temperature is affected by many factors, such as slag moisture content, type of drying equipment, drying time, ambient temperature, etc.

Generally speaking, it is more appropriate to control the slag drying temperature between 150°C and 300°C. If the moisture content of the slag is high, you can choose a higher drying temperature, but be careful not to exceed the upper limit of the drying temperature of the equipment, so as not to affect the service life and safety of the equipment. If the moisture content of slag is low, you can choose a lower drying temperature, which can save energy and reduce drying costs.

In addition, the drying time also needs to be controlled during the drying process to avoid the drying time being too short or too long. If the drying time is too short, the moisture in the slag cannot be completely evaporated, which will affect the drying effect; if the drying time is too long, it will cause energy waste and affect the quality of the slag.

To sum up, determining the appropriate value of slag drying temperature needs to be considered comprehensively according to the actual situation, and at the same time, it is necessary to control the drying time and the operation status of the drying equipment to achieve the best drying effect and economic benefits.
