ABSTRACT:
A mixing drum unit for mixing a plastic resin and an aggregate includes a metal support drum and a plastic liner resting in the drum. An outer cover is secured to the drum overlying the outer end of the liner. The liner includes a cylindrical portion telescoped into the drum extending outwardly to an outer frustoconical portion having an outer end opening. The liner has a V-shaped shallow base which promotes mixing and ease of cleaning. The drum and liner include telescoping drive paddles which extend axially throughout the liner and project radially for coupling. The liner drive paddles extend into the outer frustoconical liner portion. The liner paddles have a radial wall and an inclined wall with an inner apex. The paddles are asymmetrically arranged about the drum and liner with at least one paddle spaced asymmetrically between the two adjacent paddles. The drum paddle is a metal plate projecting radially into the triangular liner paddle for direct coupling therebetween. The cover, where used, compliments and mates with the cylindrical projection of the drum projection and the frustoconical liner portion. The cover is releasably attached abutting the drum end by releasable latches.
