Abstract
The equation of balance of forces acting on a nanoparticle in the working gap of a high gradient magnetic separator with axial location of the matrix rods is presented. The equation includes the magnetic force, the force of the fluid flow and the force of the thermal motion. The solution of the equation is found by graphical methods. It is shown that the force of the thermal motion can be neglected. The developed method allows to determine the geometric parameters of the matrix ferromagnetic rod in order to extract a certain range of nanoparticles fractions. The separation is expected to be carried out in stages – at every stage the largest fraction of nanoparticles is extracted from the solution. References 10, table 1, figures 4.
