Abstract
The invention provides a breaking and separation integrated comprehensive recovery system of chrysotile tailings, which is characterized in that a fan is connected with a pulverizing host and a duster respectively by a three-way valve; 4-8 sand discharge ports are annularly formed at the bottom of the pulverizing host; an outlet of the pulverizing host is connected with a cyclone collector by a pipeline; an inlet of a screw conveyer is connected with an outlet of the cyclone collector; an outlet of the screw conveyer is conveyed to a plane revolving screen or a plane shaking screen to achieve recovery of chrysotile; integrated functions of breaking and separation are achieved; a weak magnetic separator, a ball mill and a wet weak magnetic separator are connected sequentially to form a magnetic separating system of magnetite; and the magnetic separating system is used for magnetic separating of the magnetite from dust. According to the recovery system, the sand discharge ports in the pulverizing host separate tailing waste, two production processes of grinding & asbestos fiber opening and separation are organically combined into a whole, the production cost is lowered, the energy conservation and consumption reduction are achieved, and the magnetic separating system weakly separates the magnetite to produce iron ore concentrates.
Description
Technical field
The present invention relates to the system that a kind of chrysotile tailing comprehensively reclaims valuable mineral chrysotile and magnetic iron ore, particularly relate to chrysotile tailing fragmentation and sorting integrated comprehensive recovery system, belong to the comprehensive utilization of tailing technical field.
Background technology
At present home and abroad chrysotile ore dressing all adopts traditional stage breaking, segmentation to inhale the processing technology routine of choosing, that is: dry → broken → take off the dry method wind election process of cotton → suction choosing → desanding dedusting → classification → purification.Wherein: drying nest generally adopts natural drying, rotary drying etc.; Broken and take off the cotton general carse, medium and small broken equipment such as jaw crusher, gyratory crusher, impact breaker, hammer mill, edge runner or the opener etc. of adopting; Suction selects technique generally to adopt plane gyratory screen or yawing sieve to add the equipment such as wind-force suction system and specific gravity separator.Tradition selects cotton technique fragmentation and suction operation to carry out in distinct device respectively, and process route is long, equipment is many, investment is large, production efficiency is low, and in mine tailing, valuable mineral chrysotile content is high, has caused significant wastage.
In order to reclaim valuable mineral chrysotile in mine tailing, Some Domestic enterprise, researcher also adopt wet beneficiation craft to carry out the chrysotile ore dressing and reclaim chrysotile in mine tailing.As Chinese patent ZL98121630.7, ZL97112703.4, ZL99102291.2, patent application 01131803.1 etc., the processing line that adopts the wet dressing equipment such as hydrocyclone, shaking table, flotation device to form be take water and is chosen chrysotile as medium from raw ore or mine tailing.But in the method production process, chrysotile needs the operations such as dehydration, drying, exists shortcomings such as dehydrating energy consumption is high, cycle length, complex process.
Summary of the invention
The object of the invention is to overcome prior art not enough and provide a kind of chrysotile tailing broken with sorting integrated comprehensive recovery system, it saves energy consumption and cost, is applicable to comprehensively reclaiming chrysotile and magnetic iron ore from chrysotile tailing.
Technical scheme of the present invention is: chrysotile tailing fragmentation and sorting integrated comprehensive recovery system, comprise blower fan, three-way valve, grinding main frame, dust removal machine, tornado feeder set, conveying worm, plane gyratory screen or planar sway sieve, weak magnetic separator, ball mill, the weak magnetic separator of wet type, it is characterized in that: blower fan is connected respectively with grinding main frame, dust removal machine by three-way valve, and the base circle of grinding main frame offers 4～8 sediment outflow discharging openings; The outlet of grinding main frame is connected with tornado feeder set by pipeline, and the import of conveying worm is connected with the exit of tornado feeder set, and the outlet of conveying worm is transported to plane gyratory screen or planar sway sieve, realizes the recovery of chrysotile; Blower fan, three-way valve, grinding main frame, dust removal machine, tornado feeder set form broken and sorting integrated equipment;
Weak magnetic separator, ball mill, the weak magnetic separator of wet type are connected successively, form the magnetic separation system of magnetic iron ore, the dust magnetic separation magnetic iron ore of discharging for the sediment outflow discharging opening of the dust from plane gyratory screen or the discharge of planar sway sieve, grinding main frame.
Compared with prior art, beneficial effect of the present invention is as follows: 1) by the sediment outflow discharging opening on the grinding main frame, separate the tailings waste material, chrysotile tailing is pulverized and to be taken off the function that cotton and two production processes of sorting are bound organically in one, improved work efficiency, reduce production cost, reached energy-saving and cost-reducing effect; 2) utilize this invention, chrysotile asbestos fibre sorting in time in crushing process is sent, and has effectively reduced the loss of fiber, has protected fibre length, has improved value of the product; 3), by a little less than magnetic separation system, the discrete magnets ore deposit, produce the iron fine powder.
