Calculation of the performance of the electromagnetic magnetic fluid separator non-magnetic materials

Abstract

Abstract Magnetic fluid separation is a promising area in the field of disposal and recycling of non-magnetic materials. Performance and separation accuracy are important features of any separator. The methods for calculating the productivity offered at this moment have a number of assumptions that can significantly affect the result (constant magnetic permeability of the magnetic fluid, linear change in tension along the height of the gap, etc.), and are applicable only to specific models of separators. The aim of the study is to develop a methodology for calculating the performance of an electromagnetic magnetic fluid separator of non-magnetic materials, taking into account the distribution of the magnetic field in the gap and the influence of the hydrodynamic properties of the magnetic fluid on the movement of particles in the separation zone. The proposed approach allows us to calculate the mass and volumetric capacities of the magnetic fluid separator, the dependences of the capacities for each fraction separately, and the total on various parameters of the separator (for example, on the angle of inclination of the pole pieces). The obtained results can be used to assess the optimality of the adopted parameters when designing a magnetic fluid separator. Also, the results obtained will help optimize the installations already in operation.
