This standard applies to negative pressure classification systems for grade I and grade II fly ash.
Using a high-pressure centrifugal fan as the power source, a certain vacuum airflow is formed in the system pipeline, so that the fly ash produced by coal-fired boilers is transported with the airflow through the ash conveying pipeline to the classifier, where the classifier centrifugally separates grade I and grade II fly ash.
The degree to which fine ash in the raw ash is separated out.
