Particle size dependence in high gradient magnetic separation

摘要: The performance has been studied of a high gradient magnetic separator with well defined physical and geometrical properties on slurry particles which could also be in terms size distribution, susceptibility, density. A special was constructed whose matrix three-dimensional array parallel stainless steel wires. known susceptibility density used. particle distributions for both the feed captured noncaptured products were determined. By means an analysis using dimensionless groups, it found that recovery plotted against appropriate ratio universal curve such that, at fixed flow velocity, experimental data points corresponding to wide range sizes fields all fell close this curve. Data two different velocities separate curves. probable reason is shapes are irregular, consquently, fluid drag coefficients enter into unknown approximated by spheres equivalent size.
