Investigation of the magnetic field of a separator with specific configuration of the magnetic filter

摘要

Depending on the specific features of the object of separation and the steps of the process separating apparatus are selected, to provide the maximum degree of extraction of ferromagnetic impurities. To select the correct and most suitable design of the separating apparatus is necessary pre-dimensioning of the magnetic system. The article examines mathematical model based on the finite elements method of separator with permanent magnets with a specific structure, expressed in special tapered section presence and with permanent magnets of different shapes. The specifics of the processed product impose certain restrictions on the speed of the material, the operating temperature, the humidity, etc. Using the FEMM 4.2 software are developed different versions of the configuration of the magnetic system in order to achieve a maximum degree of purification expressed in maximum extraction of ferromagnetic particles.
