On the applicability of the modified Todes formula for predicting the height of a magnetically stabilized fluidized bed

Abstract

Magnetically stabilized fluidized beds are widely used in various technologies. The study given considers the use of this physical process in the iron ore beneficiation to obtain high-quality magnetite concentrates. For this purpose, a number of devices having different capacities have been developed. A modified Todes formula is proposed to be used to control the process of separating the components of ferromagnetic suspensions in devices of different capacities operating at present, using a mathematical model predicting the porosity and height of the fluidized bed.
