Abstract

The mixing of granular material in a two-dimensional slowly rotating container is studied using a kinematic approach. A simple model is proposed to estimate the mixing capacity of a mixer when the particles diffusivity is small. Different geometries of the container are examined numerically. The mixing rate index for the case of a circular drum is derived analytically. The optimum shape of the container and the optimum filling level are discussed.
