摘要

目的。电磁多梯度分选机基质极系统几何尺寸比的选择,在保证块状材料中铁磁性杂质提取可靠性的同时提高了分选效率。利用已知的求解线性非齐次微分方程的方法,求解了外加磁场作用下多梯度磁选机矩阵极系工作间隙内铁磁体运动的动力学问题。为了验证所得结果的可靠性,采用了实验研究的方法。建立了多梯度分选机基体板极系统工作间隙内铁磁体运动的动力学问题的公式。得到了铁磁体去除轨迹的参数方程和矩阵极点系统主要几何尺寸之间的计算关系。计算结果通过实验和已知磁选装置的运行实践得到了证实。进一步发展了板式多梯度电磁分选机工作过程的数学描述,从而得到了考虑分选机矩阵工作空间主要几何尺寸的解析表达式。实用价值。分离带长度与气隙之间的分析依赖关系,表征了铁磁体在分离过程中必须通过的分离物质层的厚度,将确保分离的必要纯度和生产率。

Purpose. The choice of the geometric dimensions ratios of system of matrix poles of electromagnetic polygradient separator to increase productivity with maintaining the reliability of extracting of ferromagnetic impurities from bulk material.Methodology. To solve the dynamic problem of motion of a ferromagnetic body in the working gap of pole system of matrix of polygradient separator under the influence of an external magnetic field the known methods of solving linear inhomogeneous differential equations are used. To confirm the reliability of obtained results the method of experimental research is used.Findings. The formulation of dynamic problem of movement of ferromagnetic body in the working gap of plate pole system of matrix of polygradient separator is carried out. Parametric equation for the trajectory of ferromagnetic body removal and a calculated relation connecting the main geometric dimensions of the system of matrix poles are obtained. The calculation results are confirmed experimentally and by operating practice of known magnetic separating devices.Originality. The mathematical description of working process of a polygradient electromagnetic separator with a plate matrix was further developed, which made it possible to obtain an analytical expression that takes into account the main geometric dimensions of the working space of matrix of separator.Practical value. Accounting of obtained analytical dependences between the length of separation zone and air gap, which characterizes the thickness of the separated material layer through which the ferromagnetic body must pass during the separation process, will ensure the necessary purity and productivity of separation.
