FLUIDIZATION OF FINE MATERIALS

Research results are presented for uniform fluidization of material with a group-C granularity (according to the classification, solid particles less than 50 mu m in size are placed into this group). An experimental plant in which the hydraulic resistance of the bed was measured as a function of its height and the rotational speed of the mixer during the fluidization is described. It is established that an increase in the height of the stationary bed above 0.01 m leads to an increase in hydraulic resistance on transition to the fluidized state, especially at low rotational speeds of the mixer.
