Rotary dryer is used to dry and dehydrate the materials with high water content, which plays an important role in modern industrial area. It can make the waste sludge into usable resources and save energy conservation to achieve the sustainable development of scientific strategy concept with good economic and social benefits.
We have explained you some basic knowledge of rotary dryer in the news we published before. How to improve the drying capacity of rotary dryer is our customer's primary concern. Here we would like to share you the temperature of hot air affects the production capacity of rotary dryer. Drying capacity is affected by air temperature more seriously.
The so-called temperature of hot air and drying medium temperature are the most sensitive conditions in drying process. When the air temperature is high, the thermal energy contained in the air is high, while the humidity is lower relatively. Water moisture absorption ability is strong, and it is very beneficial to dry materials, and drying efficiency is also high. In many drying equipment, when other conditions remain the same, the basic capacity of dehydration is in accordance with the change of hot air temperature.
When choosing the drying equipment, we should be sure to have good understanding of material limit temperature. Once the material allows, we should try to choose high-temperature media.
Particularly, there are many types of drying methods, especially the fast drying. The material temperature after drying is beyond the medium temperature significantly. For example, the air temperature of air dryer is up to 250 ℃ or more, while the discharged temperature is generally below 60 ℃
