Title:
ROTATING CLASSIFIER AND VERTICAL MILL
Document Type and Number:
WIPO Patent Application WO/2014/034613
Kind Code:
A1
Abstract:
In the rotating classifier and vertical mill, a rotary separator (33) is configured by fixing multiple rotating blades (43) at a specified interval in the circumferential direction on the outer circumference between a disc-shaped upper support frame (41) and a lower support frame (42). Providing inclined surfaces (52), which are inclined at an acute angle with respect to the tangent (T) to the outer circumferential rotation track (G1) and form an indentation (51) between the outer end (43a) side and the inner end (43b) side, on the front surfaces of the rotating blades (43) in the rotation direction makes it possible to improve classification efficiency.
