Modeling an Electrodynamic Separator Based on a Linear Inductor

Abstract

A prototype of an electrodynamic separator based on a two-side linear-induction machine (LIM) for induction sorting of nonferrous metals is considered. A mathematical model is developed for studying the LIM-based electrodynamic separator. The modeling of the interaction between the magnetic field and the conductive particles is complicated by various electromagnetic (in particular, lengthwise and crosswise) and mechanical (gravity and friction) forces. Separation results from the combined impact of various forces on conductive particles. An important part of the model is made up of equations for the combined electromagnetic mechanical effect. The results of testing the pilot sample are presented. The computed paths and deviations of the particles are compared with the experimental data.
