The finished mesh of Raymond mill is adjusted between 80-325 mesh, output 1-25t/h, can grind fly ash with Mohs hardness not greater than 9.3 and humidity below 6%, if the raw material humidity is too high, Small output can be dried naturally, and large output needs to be equipped with a dryer.
FlyAsh - NETZSCH Grinding & Dispersing
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. Fly ash can be used as prime material in many cement-based products, such as poured concrete, concrete block, and brick.
Fly Ash - A Hazardous Material?
Fly ash is a pozzolan and is by far the most widely used supplementary cementitious material in the manufactured concrete products industry because of its low cost, wide availability and concrete propertyenhancing characteristics. By partially replacing portland cement, fly ash reuse as an SCM reduces the overall material cost of producing ...

Application development of fly ash ---- ultra-fine grinding
Fly ash ultrafine grinding: Because the microbeads (ultra-fine fly ash) particles are extremely small, they can be added to the concrete to fill the gaps between the cement particles, so that free water can be discharged, and the fluidity of the cement slurry can be increased. Therefore, it can be used to prepare self-compacting concrete.
