This week’s photo shows agglomerated fly ash.
Fly ash is a process by-product resulting from fines rising with flue gases during the production of power in coal-fired power plants. Although fly ash has traditionally been landfilled, it has been discovered as a valuable additive in the production of concrete, as well as other alternative uses, such as engineered fill in the construction of berms alongside highways.
In the case of concrete, agglomeration of the fine powder fly ash prior to use yields many benefits, including elimination of dust, improved product performance, and more efficient handling. In addition, during agglomeration, typically on a pan granulator (disc pelletizer), pigments or dyes can be added to fly ash in order to provide a unique color palette for use in concrete.
FEECO has been leading the agglomeration industry in equipment and process design for over 70 years. Our materials testing facility can help you determine feasibility of agglomeration for your material, and what equipment it will take to get there.
