MAGNETIC SEMIFLUIDIZATION OF GAS-FLUIDIZED FERROMAGNETIC PARTICLES

The paper demonstrates the ability to create a novel semifluidized bed reactor for gas-fluidized ferromagnetic particles. The semifluidizati on has been achieved by means of a top restraining non-magnetic screen and a solenoid around it. The principal characteristics of the magnet ic semifluidization are that the top restraining screen has an apertur e greater than the size of the fluidized particles. An experimental st udy on the mechanics of the magnetic semifluidization has been carried out. Data correlations for the minimum and maximum semifluidization v elocities and the pressure drop have been developed in terms of variou s system parameters.
