A circulating liquid fluidized bed provides a means for obtaining a uniform mixture of different particle species that would, in the conventional non-circulating mode of operation, form separate segregated layers. This phenomenon is examined experimentally for the case of binary particle mixtures and a simple model, that treats the fluid and smaller particles together as a pseudo-fluid in which the larger particle are fluidized, is shown to provide a quantitative explanation of the observed behavior.
