Document Type and Number:
WIPO Patent Application WO/2015/033312
Kind Code:
A3
Abstract:
Classifier (10, 100, 200) which is configured to classify air-entrained, crushed particulate material received from a pulveriser into a fine fraction which is expelled from the classifier (10) and a coarse fraction which is returned to the pulveriser for further crushing. The classifier (10) includes a plurality of adjustable inlet blades (37) which are arranged partially above an inlet (20) leading into a classification zone (19), an angle of the blades (37) being adjustable through manipulation of a blade adjustment mechanism (39) in order to optimise particle flow conditions inside the classifier (10). Furthermore, the classifier (10) includes a plurality of inclined pre- swirl vanes (47) which are disposed below the inlet blades (37), each vane (47) having a curved body. The classifier (100) includes a part conical member (102) which is suspended below an operatively upper exit (31) leading from the classification zone (19).
