What to do to Prevent Fly Ash From Wall Sticking During The Drying Process
1. Pre-dehydrate fly ash first
Due to the high moisture content and viscosity of fly ash, it is inevitable that materials will adhere to the feed pipe during the feeding, which will affect the smooth progress of feeding over time. Considering to this situation, we should first Pre-dehydrate the fly ash and then dying it using the rotary dryer after the moisture content of the fly ash reaches the corresponding requirements.
2. Design the lifting plate Reasonably
If the lifting plate device on the inner wall of the dryer drum is unreasonably designed, such as improper selection of the lifting plate, incorrect installation method, and unreasonable density design, which will cause the fly ash to stick to the wall during the drying process. Therefore, we need to chose a experienced fly ash dryer manufacturers who can design the lifting plate reasonably.
3. Ensure sufficient heat
The drying of fly ash is realized through the exchange between fly and hot air. If the heat in the dryer is insufficient, the required heat value of fly ash will not be obtained, thus extending the drying time in the rotary dryer. The longer the fly ash with higher humidity stays in the dryer, the greater the probability of wall sticking. Therefore, ensuring sufficient heat is important to prevent the wall sticking of the fly ash, and is also the fundamental condition to improve the working efficiency of the drying equipment.
4. Operators shall feed materials at an even speed
Due to the high humidity and viscosity of fly ash, it is easy to form agglomeration during the drying process. If the fly ash is fed too fast, it will cause the fly ash with high moisture content to accumulate in the drying drum, reduce the evaporation rate of water on the material surface, extend the retention time, and then cause the phenomenon of wall sticking. In this case, we should ensure that the operator can feed at an even speed to avoid the accumulation of materials and prevent the occurrence of wall sticking. So we should choose a experienced fly ash dryer manufacturers who have full system of after-sales service and can train our operators before the drying.
