Multi-stage Classifier
Operating
principle:
Classifier, together with cyclone separator, dedusting filter and
radial fan, forms a system of classification. Under the lashing
force of radial fan, feed materials are brought with uprising air
stream into classifying cavity from feed inlet of classifier. Under
strong centrifugal forces of high-speed rotating turbo wheels,
coarse and fine materials are separated. Fine materials in line
with size requirements go into cyclone separator or dedusting
filter through clearances among vanes of classifying wheels, while
coarse materials, together with some fine materials, lose speed
after bumping against wall and fall to secondary draught. During
strong washing of the secondary drought, coarse and fine materials
are separated once again. Fine materials go up to classifying
cavity to be classified continuously, while coarse materials fall
down to discharging outlet and let out.
