ABSTRACT:
To reduce the manufacturing costs of air-swept roller mills and comparable mills, according to the invention a segmented polygonal blade ring is provided, which is manufactured from a plurality of polygon segments, which have planar surfaces and are preferably cut to size from metal sheets. To individual polygon segments can in each case be fixed with a predeterminable inclination one or more guide blades. Preferably an outer polygon segment an an inner polygon segment with at least one guide blade form a polygon segment. Polygon segments can be linked to polygon runs and the latter to polygon blade rings with different diameters.
