DEVICE TO PURIFY FERROMAGNETIC POWDERS FROM NON- FERROMAGNETIC IMPURITIES

摘要

FIELD: separation of powder materials into magnetic and non-magnetic products. SUBSTANCE: device has basic inductor 1 and additional one 2 connected to each other at an angle. Circular windings 5 and 6 are laid down into slots of magnetic circuits. Material enters housing 8. Nonferromagnetic product is poured down into receiver 12, and ferromagnetic material is transferred towards the field, and then down chute to repurification. Repurification is carried out at lower surface of the inductors. Ferromagnetic product enters receiver. EFFECT: ferromagnetic powders of high purity. 2 dwg
