Abstract
The invention discloses an iron tailing dry separation system. Products coarsely crushed by a jaw crusher I are fed into a grizzly feeder to be pre-screened, qualified products are sieved out, oversize products of the grizzly feeder are fed into a jaw crusher II, crushed products of the jaw crusher II and undersize products of the grizzly feeder are fed into a three-layer vibrating screen together, the oversize products on an upper-layer screen of the three-layer vibrating screen are fed into a cone crusher I to be secondarily crushed, secondarily crushed products are fed into the three-layer vibrating screen, the oversize products on a lower-layer screen of the three-layer vibrating screen are subjected to dry separation by a magnetic pulley, rough concentrates after dry separation of the magnetic pulley are fed into a cone crusher II to be crushed finely, and the crushed products are returned into the three-layer vibrating screen to form closed-circuit crushing screening. The iron tailing dry separation system is simple and practical, the new strong-magnetic plate-type dry separation machine can effectively extract iron in iron tailing, ore sand size grading is realized, use in the follow-up procedures is convenient, the iron tailing can be comprehensively utilized, the comprehensive utilization of resources is realized and the damage of the iron tailing to the environment is reduced.
Description
Technical field
The present invention relates to tail iron ore deposit technical field of comprehensive utilization, particularly relate to a kind of iron tailings dry separation system being applicable to the extraction of iron ore concentrate and the classification of ore in sand form in tail iron ore.
Background technology
Iron and steel is indispensable material in industrial development, and demand is huge, and China is also iron and steel producing country the biggest in the world simultaneously.Need a large amount of iron ores in steelmaking process, domestic iron ore material comparatively horn of plenty, but grade is relatively low, produces a large amount of low-grade ores in recovery process; In iron ore dressing process, also a large amount of iron tailings will be produced simultaneously.A large amount of tail iron ore not only land occupations, also pollutes the environment, causes the potential safety hazard in mine tailing mining area.Meanwhile, same containing valuable elements such as iron in tail iron ore.
For iron tailings, how to make better utilization, extract wherein have valency ferro element, make iron tailings obtain comprehensive utilization is a hang-up simultaneously always.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of iron tailings dry separation system.
The present invention is achieved by the following technical solutions:
A kind of iron tailings dry separation system, include jaw crusher one, grizzly feeder, gyratory crusher one, jaw crusher two, gyratory crusher two, three-deck vibrating screen, board-like dry-dressing machine and magnetic pulley, during production, the iron tailings of bulk enters PE600 × 900 jaw crusher 1 and carries out coarse crushing, coarse crushing product feeds described grizzly feeder and carries out prescreening, screen out qualified products, the oversize of grizzly feeder feeds jaw crusher two, the crushed product of jaw crusher two feeds three-deck vibrating screen (wherein polyurethane screen web tier 30 × 30mm together with grizzly feeder undersize, lower floor 12 × 25mm), the upper sieve oversize of three-deck vibrating screen feed described gyratory crusher one carry out in broken, middle crumble product feeds three-deck vibrating screen again, the lower screen oversize (-30 ~+12mm) of three-deck vibrating screen is through described magnetic pulley dry separation, it is in small, broken bits that rough concentrate after magnetic pulley dry separation feeds described gyratory crusher two again, product after fragmentation returns in three-deck vibrating screen again, formation closed circuit crushing is sieved, and the thick mine tailing after magnetic pulley dry separation removes rough sand stockpile, the undersize (-12mm) of three-deck vibrating screen is again through described board-like dry-dressing machine dry separation, and the thin concentrate of dry separation removes thin concentrate stockpile, and the thin mine tailing of dry separation removes thin ore in sand form stockpile.
Described jaw crusher one is PE600 × 900 jaw crusher; Described grizzly feeder is GZT1042-2V grizzly feeder; Described gyratory crusher one is GP11F C gyratory crusher; Described jaw crusher two is C80 jaw crusher; Described gyratory crusher two is GP11F F gyratory crusher; Described three-deck vibrating screen is 2YAH2460 three-deck vibrating screen.
Advantage of the present invention is: the present invention is simple and practical, and the strong magnetic sheet formula dry-dressing machine that employing is newly entered effectively can extract the iron in iron tailings; Realize ore in sand form grading, be convenient to later utilization; The CHARACTERISTICS OF TAILINGS SAND problem of complex utilization solved, realizes comprehensive utilization of resources, decreases the harm of iron tailings to environment.
