摘要

A propeller (1) for stirring solid-in-liquid suspensions inside a treatment tank (2) is disclosed, comprising a generally axial element (6) consisting of at least a blade (6b) with helical development and a generally radial element (7) consisting of a plurality of vanes (15) with generally radial development. Said elements (6, 7) belong to a single central shaft (5) defining a longitudinal rotation axis (Z) along which said elements are coaxially arranged one after the other. <IMAGE>
