Detailed characterisation and separation of fly ash fed to ...

01-01-2017 · A Reflux Classifier (RC) with parallel inclined channels located above a liquid fluidised bed was used to fractionate the fly ash feed into different flow fractions with a narrow range of density. Note that this mode is very different to the IRC arrangement adopted in this study for recovering and concentrating the cenospheres on a continuous basis.

Fly Ash Moisture | Fly Ash Moisture Gauge - Moist Tech

Fly ash in this application must be stockpiled and conditioned to its optimum moisture content to ensure that the material is not too dry and dusty or too wet and unmanageable. When fly ash is at or near its optimum moisture content, it can be compacted to its maximum density and will perform in an equivalent manner to well-compacted soil.
