MAGNETIC SEPARATOR Russian patent published in 2003 - IPC

FIELD: separation of ferromagnetic admixtures from flow of loose diamagnetic material. SUBSTANCE: proposed separator has housing, magnetic system including permanent magnets separated by flat ferromagnetic concentrators; like poles of magnets are directed towards each other and their planes are located vertically. Concentrators are made in form of trapezium or triangle or their combination. Height of concentrators increases in way of motion of material being separated. Pitch and height of poles are related by the following ratio τ = (1,01÷1,25)h, where τ - is pole pitch of magnetic system and h is height of poles. EFFECT: enhanced efficiency. 4 dwg
