Title: Method and apparatus for mixing viscous materials

Abstract: A method and apparatus for mixing viscous materials in a double arm mixer having a container with a pair of spaced apart shafts pivotably disposed through the container and a plurality of mixing plows connected to the periphery of each shaft in spaced apart relationship. When the shafts are rotated in opposite directions, the working tools force the viscous material to the bottom of the container so that at its densest point, it interacts between the shafts before it is divided. The velocity of the individual particles varies in proportion to their distance from the axis from each of the shafts so that the shafts produce a radial inversion on a random basis as the particles are moved. The centrifugal force causes a radial shifting of the material from the axes of each shaft toward a path of higher velocity before the particles are divided. This results in uniform shear with a random division of all of the particles being mixed.
