Radiotracer investigation of the pulp flow characteristics in the superphosphate production chamber

By means of radiotracer51Cr impregnated in the solid phase the residence time distribution of the pulp in the mixing chamber was obtained. The mathematical model constructed on the basis of the experimental distribution showed an unsatisfactory functioning of the reactor. Ways were proposed to correct this shortcoming, both in the existing chamber and in that which is being designed for a new plant.
