Calculation of the Electromagnetic Repulsion for Eddy Current Separation About the Scrap Copper
Eddy current separation is a technology used to separate the nonferrous metal materials from the mixture of solid waste based on the eddy current effect. It is usually used in the field of resource recovery and recycling. In the process of eddy current separation, the electromagnetic repulsion plays a decisive role on the separation effect. This paper selects the spherical, cylindrical and quadrilateral copper particles in the actual separation process because of their commonness, establishes three kinds of electromagnetic repulsion models about the copper particle eddy current separation. At the same time, owing to their more obvious conductivity differences, red copper and bronze are chosen for the calculation of the separation angle when three different shapes of scrap coppers departing from the surface of the eddy current separator's conveyer belt. The result of calculation may give some references for the actual eddy current separation process.
