Fly ash classifier, fly ash classification method and production method of spherical fly ash particles

摘要

An object of the present invention is to provide a classification apparatus and classification method for classifying the fly ash with a high degree of accuracy.SOLUTION: This apparatus comprises a classifier 2 for classifying fly ash, an introduction part for introducing fly ash into the classifier 2, a lead part for leading light fly ash from the classifier 2, a heavy fly ash discharging from the classifier 2 and a discharge unit 5 for a classifier 2 and the introducing portion inlet side connecting hole 6 provided in the connecting portion, classifier 2 and the outlet portion discharge side connecting hole 7 provided in the connecting portion of, classifier 2 and is provided above the discharge side connection hole 19 provided in the connecting portion of the discharge portion 5, a position fly ash introduced from the introduction-side connecting hole 6 in the classifier 2 collides, the introduction-side connecting hole 6 is provided with a disintegrating body which bounces back in response to collision of the fly ash introduced from the discharge side space 6, and the inside of the classifier 2 is provided with a discharge side space where a heavy fly ash is present at a position below the disintegrating body, in the light fly ash to deriving unit And a flow-side space to be dynamic.(FIG.
