Mining ore dressing meeting produces a large amount of metal tailings, and metal tailings not only takies tract, also causes soil erosion, channel filling, water pollution, environmental destruction.The comprehensive development and utilization of mine tailing is Mine Sustainable Development and fundamentally administers the important channel of mine environment.Being the storage that reduces metal tailings, fundamentally eliminating metal tailings harm and have positive meaning, is a kind of way of Initiative defence metal tailings harm.
Metal tailings is a kind of metal slag taking calcium-silicate as master, how to be made up of silicate, carbonate and number of chemical element, and the materials such as its composition and many building materials, light industry, inorganic chemical industry approach, and has possessed the potential characteristic of value added applications.
In existing public technology, the comprehensive utilization of metal tailings is related to cement and generally there are two kinds of modes cement mixture aspect, a kind of is to replace the method for part sa raw material as the batching of production clinker using metal tailings, as utility model patent CN1657466A " process for calcining cement clinker that in copper, Pb-Zn tailings, silicon dioxide activity is adjusted ", 1067421A " utilizing copper mine tailing to produce clinker " etc., its essence is only embodied in has saved part of clay resource.Utility model patent CN1616372A " portland cement of industrial tailing " discloses a kind of industrial tailings cement technology, it be according to the clinker of constant weight proportioning, gypsum be milled to 80 μ m with the magnesia mine tailing mixing of treated calcium ovendry power and tail over≤3% make.
Metal tailings will be done grinding processing.Flour mill is refluxed to struggle against by frame, air duct, disc-grinding mechanism, grinding roller mechanism, feed mechanism, separating mechanism, negative pressure powder-suction structure, coarse fodder and forms.Air duct is that tubular body is arranged in frame.Disc-grinding mechanism is arranged on the frame support in air duct.Mill is driven and is rotated by motor transmission mechanism output shaft; Grinding roller mechanism is symmetrical two grinding rollers in mill top, grinding roller cylindrical is low-angle taper, grinding roller inner circle is connected with roll shaft by duplex bearing, roll shaft back segment is fixedly connected with a swing arm through air duct barrel, regulate the gap of swing arm capable of regulating milling roller surface and mill face, thereby regulate the particle diameter of abrasive particle.Grinding roller is that frictional force drives passive rotation.
Feed mechanism is made up of barrel, conveying worm, hopper, bucket cover, tremie pipe.On the hopper of cone tubular, be fixed under bucket cover along on face along limit, bucket cover is fixed on air duct inwall by four boss of bucket cover outer, and hopper lower port is fixed a tremie pipe, and tremie pipe lower port is top, central area between two grinding rollers.Conveying worm is through air duct barrel and hopper headwall, and metal tail slag is fallen into after conveying worm by barrel, is advanced to hopper, then goes out tremie pipe and fall into mill central area.
Separating mechanism is made up of motor transmission mechanism, vertical shaft, rotating disk, fan blade.Be fixed on the vertical shaft rotary of the motor transmission mechanism drive suspension type in frame, vertical shaft is fixed in the Central boss of rotating disk through its hypomere of sleeve pipe of negative pressure powder-suction structure special pipe, Central boss and a Taper Pipe platform are fixed, Taper Pipe platform bottom is fixed with a lower annulus, and Taper Pipe platform top is fixed by three connecting rods and upper annulus.The uniform ring week vertical blade of fixing the blind shaped that several can hand adjustment angle between upper and lower annulus, rotating disk fan blade and air duct inwall are possessed spacing, and the upper and lower anchor ring of rotating disk is possessed moving fit clearance with the upper circular ring cover of air duct, the bucket cover of hopper respectively.
Negative pressure powder-suction structure is that on air duct, circular ring cover upper cover formula is connected and fixed a special pipe air channel, special pipe air channel and an air exhauster pipeline connection, and the air exhauster port of export is communicated with collection powder case.In the time of abrasive dust, air exhauster is opened air-flow and is entered by mill below, the ring Zhou Tongdao flowing through between mill and air duct, fine powder on mill is upwards taken away, flow into the circular ring path between bucket cover and air duct wall from the space between hopper gabarit and air duct again, thereby place enters rotating disk by fan blade, under the centrifugal action of fan blade and rotating disk formation, coarse dust outwards separates and falls into former passage, fall into the coarse fodder backflow bucket mill from mill gabarit, fine silt is circular ring cover medium pore suction special pipe air channel from air duct, thereby is inhaled into collection powder case.On mill coarse dust also can be centrifuged power effect fall from mill limit fall into coarse fodder reflux bucket.
The defect of this doffer being made up of bucket cover, hopper and tremie pipe is: powder falls into two mill central areas between grinding roller, relies on outer radial and disperses and just can enter grinding roll surface.Because powder is with humidity; usually can lump or be consolidated into two the heap Duo of central authorities phenomenons between grinding roller; the open and flat grinding face that enters mill can not scatter; the piece footpath of caking enters greatly grinding face and reduces work efficiency; after the heap Duo of central authorities raises; tremie pipe blanking is beaten from top to bottom on the heap Duo of central authorities, and part blanking directly falls into fast coarse fodder backflow and struggles against, reduces equally work efficiency under the Duo slope effect of central authorities' heap from mill limit.
