INVESTIGATION OF THE PROCESS OF DIAMAGNETIC PARTICLE SEPARATION IN A HIGH-GRADIENT ORDERED-STRUCTURE MAGNETIC FIELD

摘要

On the basis of the model of a flow-type magnetic filter with a transversely magnetized ordered system of long ferromagnetic rods of rectangular cross section, the process of high-gradient magnetic separation of microscopic diamagnetic particles (potato starch granules of sizes 8-30 μm) from a liquid suspension has been investigated. The registered laws of change in the concentration and size distribution of particles at the suspension outlet from the filter agree with the theoretical conclusions obtained from the analysis of the magnetic field structure and the character of the particle motion in the filter volume.
