FLY ASH DRYER

Fly ash is fed into the rotary dryer. After passing through the dryer, the dried material is discharged to a transfer conveyor for further sorting and separation. The vapor from the process is pulled through a cyclone that is specifically designed to deal with the fine dust, as well as a high-temperature baghouse which removes all fine particulates from the vapor stream.

1. In the coal fired power plant, the fly ash has two discharging style: one is dry discharging style, the other is wet discharging style.
2. In the rapidly developing cement industry, as the cement production mixing materials, the dry fly ash market is rather considerable. The physicochemical properties of wet fly ash are basicly same as the dry fly ash, but as there is big moisture content (maximum is amount to 45%), the wet fly ash can not meet the requirements of cement production. As a result, the wet fly ash can only be piled up as waste, and occupy many storage place, even pollutes the environment.
3. Then, how to dry the wet fly ash ? 
After years' research, Yuhong Machinery developed one new type fly ash dryer. It has the advantages of low energy consumption, simple drying process, large drying capacity, etc.  Fly ash dryer from yuhong Machinery can dry the wet fly ash from moisture content 45% to about 8% in large quantity directly.
