Özet
Magnetic filters are effectively used for the removal of low-concentration and submicron-sized magnetic particles from industrial liquids and gases. The matrices of magnetic filters are composed of ferromagnetic fillers (balls, rods, plates, metal shavings, etc.) that can be easily magnetized in an external magnetic field and have various geometries. Calculating the high-gradient magnetic fields formed in the pores of the filled beds and determining the force effect are crucial for the theory and practice of magnetic filtration and separation. Due to the tiny size of the pores, direct measurement and evaluation of magnetic field intensity in these regions are challenging. Therefore, various approximate methods are employed to model magnetized filled beds. This study primarily investigates the magnetization characteristics of filled beds composed of ferromagnetic balls. The analytical expressions of the main magnetization curves of this type of filled bed have been obtained. These expressions have been formulated in away that can be easily used in engineering practice calculations. The theoretical calculations obtained have been compared with some experimental results from the literature, and recommendations have been made for the use of these formulas in the design, control, and optimization of magnetic filters.
