PRACTICAL COMPONENT IDENTIFICATION SYSTEM IN METAL CONTAINING RAW MATERIAL OF NATURAL OR ANTHROPOGENIC ORIGIN Russian patent published in 2010 - IPC B07B15/00 

FIELD: mining.

SUBSTANCE: invention can be used in separators or process control systems for the raw material of natural or anthropogenic origin separation, and can be used for pieced raw material industrial enrichment, which practical component presented with the different ferromagnetic and non-ferromagnetic metal intrusions, containing in metallurgical industry slugs of in black or colour metals enrichment tailings. Practical component identification system in metal containing raw materials of natural or anthropogenic origin includes a belt conveyor with a flat operating branch surface, a measurement system, located over or under the conveyor belt operating surface and connected to a screen. The measurement system as a metal - sensitive device, which contains induction sensors, located in parallel to the conveyor operation branch surface, executed with possibility of practical component content identification in separate pieces of metal containing raw material. A dislocation between sensors centers in projection to a plane, perpendicular to the conveyor belt movement vector, R_s - defines from a equation d_s≤2·R_s, where d_s - controllers centers displacement in projection to the plane, perpendicular to the conveyor belt movement vector; R_s - controllers range of sensitivity radius, for the minimum size piece with metal intrusions. The measurement system connected to computing device for the geometrical centers coordinates calculation and raw material pieces parametres calculation, generating the screening devive control signals.

EFFECT: metal containing pieced raw material efficiency and screening quality increase.
