Abstract: Rotating fluidized beds in vortex chambers exhibit excellent properties of mass, heat and momentum transfer. When operated in high-G, they also have the unique ability to fluidize small cohesive particles. The use of a rotating fluidized bed in a vortex chamber for the granulation of particles is investigated in this work. In a first step, an experimental parametric study of the operating conditions of the vortex chamber is made to determine their effects on the solids losses and the properties of the particle bed. Then, small particles are granulated in the aim of reaching a target particle size distribution and composition. The granulation performance of the vortex chamber is assessed in another parametric study of the operating conditions.
