UNIVERSAL MAGNETIC SEPARATOR Russian patent published in 2005 - IPC

FIELD: mining; dressing of minerals with the help of a method of magnetic separation of pulps.

SUBSTANCE: the invention is pertaining to the field of dressing of minerals f minerals with the help of a method of magnetic separation of fine-dispersed pulps, selective separation by magnetic properties of the finely dispersed dry magnetic powder mineral mixtures. The technical result is combining of an effective breaking- down of magnetic pudding stones and floccules with a high selectivity of magnetic separation of fine pulps and finely-dispersed dry magnetic powder mineral mixtures. The separator contains a magnet system, which has been made out of permanent magnets capable to rotate with a regulated frequency. The magnet system is made out of three layers of permanent magnets: a central layer - with magnets in the form of rectangular prisms, additional layers - with magnets in the form of the truncated prisms. The separator is also equipped with a lateral separating chamber with a movable gate separating an area of a demagnetization and breaking-down of the magnetic floccules from an area of additional purification and separation with a capability of separation of mineral mixtures both in the form of fine pulps and in a dry state.

EFFECT: the invention ensures a combining of an effective breaking-down of magnetic pudding stones and floccules with a high selectivity of magnetic separation of the fine pulps and finely-dispersed dry magnetic powder mineral mixtures.
