Prodn. method for spiral loader - uses cast light metal with runner and housing components of varying delivery capacities

摘要

The spiral loader can involve varying blade pairs, that with the lower delivery volume comprising a housing blade (10) and a runner blade (11), while that with the greater delivery volume consists also of a housing blade (12) and a runner blade (13). The two runner blades (11, 13) belong to runners with the same dimensions. The housing blades (10, 12) are of varying strength, produced by millings. The one runner blade (13) moves the essentially greater eccentricity (14) than the other (11). The circular movements with different eccentricity of the runner blades (11, 13) are represented by circles (16, 15) of varying size. USE - As a spiral loader.
