FlyAsh - NETZSCH Grinding Dispersing
Fly Ash. Fly ash is a fine powder that is a byproduct of burning pulverized coal in electric generation power plants. Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement.

CONCRETE Optimizing the Use of Fly Ash in Concrete
Schematic layout of a coal-fired electrical generating station (Sear 2001). In the production of fly ash, coal is first pulverized in grinding mills before being blown with air into the burning zone of the boiler. In this zone the coal combusts producing heat with tempertures reaching approximately 1500°C (2700°F).
