Industry Coal, Fly Ash Processing
Summary
Vostosun provides customers with fly ash drying solutions for coal plants. Fly ash is the primary solid waste produced by coal plants. It contains SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2, etc. Therefore, fly ash has a wide range of applications, such as a primary ingredient of bricks, agricultural fertilizer modifiers, adsorption materials, and environmental protection materials. It also can be used in admixtures of concrete, thus lowering the cost of cement and fine aggregate.

The fly ash drying process provided by Vostosun contains three steps: spreading, drying and cooling. First, spread the wet fly ash (20-30% moisture) from feeder in the feed section of the dryer. Next, the small block fly ash can be distributed in the whole drying space by the lifting plate inside the dryer cylinder, and evaporated by the hot blast stove. Last, the dried material can be cooled to the proper temperature by the rotary cooler, and can be sent to the product warehouse through the discharging mouth by the conveyor system.
