The fluidized bed process presented in this paper is suitable to recover solids from solution in
form of granules. Solution is sprayed into the bed and, as the solvent evaporates, solid
material is deposited on the surface of fluidizing particles. During this process, particle
growth takes place by surface layering and/or agglomeration. A special grinder is used in the
fluidized bed to control particle growth by causing selective disintegration of large particles.
For steady state operation, the most important task is to determine the existing particle size
distribution in the fluidized bed. A special method was developed to measure torque and
stress fluctuations in the bed of particles. Using a correlation between torque and particle size,
this method and device can be used for direct control of the rotation speed of the grinder to
produce granules of given size in the fluidized bed. In this paper, the results of torque
measurements and their correlation with particle size are presented.
