OF A MIXTURE OF MAGNETIC AND NONMAGNETIC MATERIALS

The velocity of the beginning of fluidization and 
the porosity of a bed were investigated for a mixture of cast-iron 
(dp = 1.086 mm) and copper (dp = 1.086 mm) particles 
fluidized in a homogeneous external magnetic field of an intensity 
of up to 5662 A/m. By analyzing the forces that act 
on the magnetic particles the authors obtained an expression for calculating 
Umb in a bed consisting of a mixture of magnetic and nonmagnetic 
particles. The calculation results are compared with the experimental 
data.
