Fly Ash Air Classification - Beneficiation | Sturtevant ...
Sturtevant’s Solution: Fly Ash Air Classification. Sturtevant Air Classifiers are able to control the fineness of fly ash by air separating it at 200-325 mesh (75-45 microns), thereby reducing the LOI carbon content by 50% or more to a level that is appropriate for use in cement, as a filler for land reclamation, soil improvement, lightweight aggregates, and agricultural uses.
MP618™ Multi-Process Fly Ash Beneficiation …
Increased Fly Ash Sales. Decreased Cost Profile and Footprint. The innovative MP618 Multi-Process fly ash beneficiation technology uses a proven thermal process that reduces loss on ignition (LOI), ammonia, activated carbon, mercury and other contaminants making your formerly unusable fly ash in current production or legacy ash stored in ponds or landfills immediately marketable.

Additionally, coal fly ash with ammonia content above 100 ppm can cause
Fly ash - Wikipedia
Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boilers combustion chamber (commonly called a firebox) is called bottom ash.
