ANTHROPOGENIC RAW MATERIALS SEPARATION EQUIPMENT, REPRESENTED WITH METAL CONTAINING WASTES AND OFF-QUALITY ORES Russian patent published in 2010 - IPC B07B15/00 

FIELD: mining.

SUBSTANCE: invention can be used for enrichment of raw materials, gained form anthropogenic fields development, formed in result of storing metallurgical industry slugs or underground or opened minerals field development enterprises off-quality ore. Anthropogenic raw material separation equipment, represented with metal containing wastes and off-quality ores, contains a receiving bin, a feeder - doser, conveyor, raw material practical component content identification system, screen, bins for mineral content with practical component, and empty rock. The device additionally contains vibration separator executed with ability to form a layer containing of separate pieces of raw material on the conveyor belt. The vibration separators drive connected to separation control block, which contains frequency converters, providing possibility of the conveyors feeder - doser drive rotation velocity change, and conveyor belt filling with raw material pieces grade, dependently on its physics - chemical and granulometric content accordingly. Over or under the conveyor belt a measuring system located, which connected to computer block, executed with possibility of practical component content identification, calculation of raw material pieces geometrical centers coordinates and their dimensions with help of a motion sensor, which interacts with conveyor belt operating branch or one of the conveyor rollers. The screen located on the reload conveyors end and designed as a system of row nozzles, attached to electrical valves, connected to high speed gas or fluid flow and also connected to the computer block, which executed with ability to open valves and nozzles and supply gas of fluid inside them, according to the metal containing pieces coordinates and dimensions. Nozzles axis are space oriented with possibility of deflection form metal containing pieces falling down trajectory under fluid or gas flow action and moving to the appropriate receiving belt.

EFFECT: raw material separation quality increase in a wide diapason of granulometric content, device operation efficiency increase.
