An approach is proposed to carry out multivariate calculations of the magnetic field distribution in the working gaps of a plate polygradient matrix of an electromagnetic separator, based on a combination of the advantages of two- and three-dimensional computer modeling. Two-dimensional geometric models of computational domains are developed, which differ in the geometric dimensions of the plate matrix elements and working air gaps. To determine the vector magnetic potential at the boundaries of two-dimensional computational domains, a computational 3D experiment is carried out. For this, three variants of the electromagnetic separator are selected, which differ in the size of the working air gaps of the polygradient matrices. For them, three-dimensional computer models are built, the spatial distribution of the magnetic field in the working intervals of the electromagnetic separator matrix and the obtained numerical values of the vector magnetic potential at the boundaries of the computational domains are investigated. The determination of the values of the vector magnetic potential for all other models is carried out by interpolation. The obtained values of the vector magnetic potential are used to set the boundary conditions in a computational 2D experiment. An approach to the choice of a rational version of a lamellar matrix is substantiated, which provides a solution to the problem according to the criterion of the effective area of the working area. Using the method of simple enumeration, a variant of the structure of a polygradient matrix with rational geometric parameters is selected. The productivity of the electromagnetic separator with rational geometric parameters of the matrix increased by 3–5 % with the same efficiency of extraction of ferromagnetic inclusions in comparison with the basic version of the device

“…In author's works [7,8], the possibility of applying genetic synthesis and simulation methods to determine the possible structures of polygradient media of magnetic separators is substantiated. The basis of algorithms of genetic synthesis is formed by genetic operators of crossing, replication, mutation and spatial inversion, and the order of application of these operators is represented by the genetic model [9].…”

The distribution of the magnetic field in the working zones of synthesized polygradient media is studied using a computational experiment. The distribution of the magnetic field is carried out by the numerical finite element method, realized with the help of the ELCUT program complex. It is substantiated that instead of studying the field distribution in the entire interpolar zone of arbitrary structure, it can limited by the field studies in a characteristic, periodically repeating region, taking into account its symmetry. For the studied structural compositions of polygradient media using the ELCUT program tools, two-dimensional geometric models of the working interpolar zones have been developed, taking into account generally accepted engineering assumptions. A comparative analysis of the distribution of induction and force function of the magnetic field in the working gaps of the synthesized structures of a lamellar polygradient medium of a given configuration is performed

The paper deals with the main approaches for estimation of homogeneity degree of magnetic field in polygradient medium of magnetic separator. As an indicator of the inhomogeneity of field was accepted inhomogeneity coefficient. It shows how many times the strength of field at research point differs from the strength of homogeneous field. Numerical simulation of distribution of the magnetic field in interpolar working zones in a two-dimensional formulation for six synthesized structures. The plate in form of rectangular triangle was adopted as an elementary monostructure was carried out. Comparative estimation of inhomogeneity degree of magnetic field along characteristic lines of working zones of synthesized structures of magnetic separators polygradient medium has been made. For field inhomogeneity research as characteristic lines were accepted lines that connect the vertices of the opposing triangular plates of the matrix. The results of research can be used to choose the rational structure of polygradient medium and geometric dimensions of its plate elements.
