MAGNET SEPARATOR Russian patent published in 2009 - IPC B03C1/12 

FIELD: instrument making.

SUBSTANCE: invention is related to the field of magnet separation of fine-dispersed materials and fine particles in the form of dry powder. Magnet separator comprises body that consists of settling chamber and regeneration chamber, magnet rods installed inside hollow tubular settling elements with the possibility of reciprocal motion, device for displacement of magnet rods and device for removal of magnet admixtures. Additionally separator contains chamber for preliminary separation of settled magnet admixtures from separated material, which is installed between settling chamber and regeneration chamber. Every section of tubular settling elements located in chamber of preliminary separation is equipped with two helical fixed knives. Initial sections of knives are joined and located on upper surfaces of hollow settling elements in the area of transition of settled magnet admixtures from settling chamber into preliminary separation chamber. Final sections of helical knives are radially turned in different sides relative to initial sections by 90° and are located on side surfaces of hollow settling elements in the area of transition of settled magnet admixtures from chamber of preliminary separation into regeneration chamber.

EFFECT: increased efficiency of separation and reduced losses of material.
