This paper describes the results of an experimental and theoretical study of a large water elutriator. The earlier eddy diffusion model (Biddulph, 1979) is extended to provide a simple representation of “wall‐flow” of particles. A reasonably good agreement with experimental separations of standard mixtures is achieved at water velocities of interest in the field of materials recycling. The model is used to explore some design parameters including feed location and length of column. The implications of separating mixtures containing a range of particle sizes and shapes is considered.
