ABSTRACT:
A mixing vane is mounted interior of a drum having a plastic lining--preferably a vinyl lining. Preferably two mixing vanes covers a cylindrical solid angle of 240.degree. while 120.degree. remains unoccupied to permit convenient pouring of the contents from the barrel. The mixing vane is preferably constructed with a L-shaped section with the bottom of the "L" fitted to the interior of the lined drum and the vertical member of the "L" protruding outward from the barrel wall as the mixing vane. In the preferred embodiment, the vertical member of the "L" is disposed along a helical path to produce directional movement of the barrel contents during barrel rotation. Preferably, the mixing vane is injection molded from vinyl or polyethylene. In fastening to the sidewall of the 55 gallon, the mixing vane is softened at the bottom of the "L" by either placement in a vinyl solvent or heating to produce a sticky surface. The vane is placed, preferably by clamping, to the inside surface of the vinyl coated 55 gallon drum. There results a complete and simple bond of the vane to the drum which can withstand the temperatures of materials placed within the drum and effect desired mixing of the drum contents.
