“…Thus, our analysis of publications [10][11][12][13][14][15][16][17][18] makes it possible to argue that at present there are no systemic solutions for determining the distribution of a force function in the working zones of devices for magnetic separation. Most publications report results from studying the influence of a shape and geometric dimensions of the magnetic systems of separators on the magnetic field distribution.…”

A variety of forms, structural assemblies and magnetization directions of permanent magnets makes it possible to construct new magnetic systems for separation devices with the required topology of magnetic field in working gaps and acquisition of new functional properties [9]. Studies in this field are of theoretical and practical interest. 2. Literature review and problem statement Numerous publications report studies into magnetic systems of separators on permanent magnets. Features in using magnetic separators on permanent magnets were considered in paper [10]. It was shown that separators are distinguished by simplicity of the structure, low power consumption, they

“…In [5] experimental studies of the magnetic field induction distribution in the simplest case -for single and paired magnetic elements in various modules of magnetic separators were performed. The possibility and practical expediency of using the superposition principle to establish the resulting induction characteristic of the field between opposing magnetic elements is shown to replace the actual simulation with the calculated one.…”

“…As the analysis of publications [3][4][5][6][7][8][9] has shown, the calculation of the magnetic field in the working interpolar gaps of magnetic separators is a rather complex task, which for most configurations of magnetic systems has not been solved analytically until now, and the experimental methods are rather laborious. When developing new designs of magnetic separators to obtain information on the distribution of magnetic field induction in working gaps, it is expedient to use numerical calculations with the use of appropriate computer programs.…”

Purpose. To carry out research the influence of magnetic system configuration (shape and size of the permanent magnets) on magnetic field spatial distribution in working area of new structure design magnetic separator with active front surface by numerical methods. Methodology. We have applied the magnetic field numerical simulation for permanent magnets system in absence of electrical current in magnetostatic approximation. We have solved the problem by using finite element method. Research of permanent magnets cross-sectional shape influence made in the two-dimensional formulation using software package Elcut. Research of magnetic field induction spatial (three-dimensional) distribution in new construction magnetic separator working area is conducted using software package COMSOL Multiphysics 3.5a. Results. Magnetic flux density maximum in the immediate vicinity of permanent magnet surface provide magnets with spherical and trapezoidal cross-sectional shape. At a distance from pole surface, where the separation process working, magnetic field density produced by trapezoidal and spherical cross section magnets, substantially lower in comparison with rectangular magnets. Rectangular and rectangular with beveled corners cross-section shape magnets create approximately same magnetic field intensity not significantly different in weight. Analysis of the spatial distribution of magnetic field induction in the working area of a new construction magnetic separator has shown that a strong magnetic field with high magnetic flux density gradient value is formed in the interpolar working volume. Originality. For the first time research of magnetic flux density distribution in working area of new construction magnetic separator is conducted. Developed device feature is complex spatial distribution of magnetic field. Practical value. Results of research can be used for selection of rational parameters of separator magnetic system. Received results also can be used for determination of separator force characteristics. References 11, figures 8.

Поставленные задачи решены с использованием численного метода конечных элементов. Показано, что кольцевые постоянные магниты с прямоугольной формой поперечного сечения обеспечивают наиболее высокие показатели магнитной индукции в рабочих воздушных зазорах на требуемых расстояниях от поверхности магнитов. В результате анализа пространственного распределения индукции магнитного поля установлено, что в межполюсном рабочем объеме сепаратора образуется достаточно интенсивное магнитное поле с высоким значением градиента индукции. Отмечена целесообразность использования результатов исследования для выбора рациональных конструктивных параметров магнитной системы и определ...
