Wind classifier

摘要

The wind classifier has a rotating classifying wheel with air flowing inwards against its centrifugal direction, scoops parallel to the rotation axis forming a crown, with their ends in opposite recesses of end limiters concentric with the classifier wheel hub. The hub (1) and the end limiters (2,3) form a classifier wheel base body, into which the scoops (4) can be fitted in positions opposite each other. The end limiters are detachably attached to the hub by connecting elements (12,13). The classifier wheel base body may be fabricated as an one piece body and have intake passages for fine quantities of classified air.
