ABSTRACT:
An assembly which is adapted for mounting inside a mixing drum and a mobile system for mixing and dispensing concrete includes fin structure for mixing and guiding a substance when the mixing drum is rotated. The fin structure is constructed of a lightweight polymeric material which is resistant to abrasion and is many times lighter than steel. As a result, the weight of such a system is reduced in comparison to systems which were heretofore known. Preferably, the fin structure is fabricated from a polymer which tends to wear smooth rather than rough, which increases the cleanability of the fin structure over its entire design life. Novel structure for securing the fin structure to an outer wall of the mixing drum is also disclosed.
