Abstract

The relevance Cleaning of bulk agricultural products from metallomagnetic impurities is an urgent problem that needs to be solved today, as it leads to significant material and economic losses. Magnetic and electromagnetic purification methods are based on the difference in the magnetic properties of the separated products, mainly on the difference in their magnetic susceptibility. In the working area of the separator, there is a zone of attraction of magnetic particles, the height of which is determined by the minimum distance between the working body and the surface of the fixed pole, and the zone of transportation of the magnetic product to the unloading site. The magnetic field in the working area of the separator is created by systems of permanent magnets or electromagnetic systems with winding. Parametric design is the basis for conducting design work during the development of an electromagnetic separator and allows you to clarify the final purpose of the installation already at the early stages of the project. Aim of research This article deals with optimization of design and mode parameters of electromagnetic separator with permanent magnets. Research methods In this study it is proposed to use nomogram-parametric design, both electromagnetic separator and its mode parameters. Nomogram parametrization consists in creating a nomogram to determine the mode parameters of electromagnetic separator with permanent magnets. Results Based on the established relationship of design and mode parameters of separation in the separator's working zone, a nomogram was developed that allows to determine the parameters of the electromagnetic system, the value of magnetic induction, depending on the heterogeneity of the magnetic field, as well as solve the inverse problem, determine the design parameters of the working zone with the given indicators of the electromagnetic system.
