FLY ASH CLASSIFYING APPARATUS

摘要

A fly ash classifying apparatus is provided to drastically increase the flow rate of air entering into a rotary part by tapering the inner diameter of a first air duct. A fly ash classifying apparatus comprises a silo, a rotary part(120) consisting of a first air duct and a raw material input pipe(123) connected mutually; a classifying device(130) classifying raw material fed through the raw material input pipe from the rotary part; a cyclone connected the classifying device and a transfer pipe; and a dust collector connected to the cyclone. The inner diameter of one side of the first air duct and the other side are asymmetrically formed. The transfer pipe is formed at higher position than the raw material input pipe. A slit part(137) changing the stream of air is formed on one side of the classifying device.
