Mechanical model of nonmagnetic mineral particles in magneto hydrostatic static separation
Base on the fluid dynamics,electromagnetism,Newtons law and some other basic theories,the paper analyses the equations of motion and Bernoulli for nonmagnetic mineral particles in magnetic fluid.And apply these theories to establish the mechanical model for the nonmagnetic mineral particles in magneto hydrostatic static separation (MHSS).In MHSS,theparticles would be stressed by gravity force,magnetic buoyancy,ordinary buoyancy,etc.The wedge-shaped magnetic poles can set up the magnetic buoyancy of which direction is straight up,and the levitation force could be stronger in ferromagnetic fluid.And it can be calculated equating normal buoyant weight to the magnetic buoyant force that any nonmagnetic substance can be floated in magnetic fluid.The paper also analyses some parameters that affect the separation result,such as the magnetic field intensity and the magnetic field gradient.These tasks may give some supports for MHSS applied in industrial.
