Summary of the invention
To the objective of the invention is in order solving the problems of the technologies described above, the preparation method of the rhombspar tailing-bricks that a kind of technology is simple, production cost is low, each item performance index are excellent to be provided.
Rhombspar tailing-bricks of the present invention is made by following method: (1) remove rhombspar mine tailing pulp screen＞and the foreign material of 5mm, through obtaining the rhombspar mine tailing of water cut＜5% after natural air drying or the equipment oven dry; (2) with solidifying agent 9～10.8 weight parts and rhombspar mine tailing 81～82.93 weight parts, that water 6.27～10 weight parts roll mix is even; (3) compound behind the mix is sent into mould, and compression moulding obtains adobe, carries out promptly getting after the maintenance again.
Solidifying agent is cement-based solidified dose in the said step (2), the long-pending 400m that reaches of its specific grain surface
2More than/the kg.
Earlier solidifying agent and rhombspar mine tailing compound mix are rolled evenly in the step (2), then the mode of water with spraying sprayed in the compound, mix while spraying into and grind full and uniform to compound.
In the said step (2); Said rolling makes that clod is broken into powdery in the compound after the dry mixing, and peels off the tailings mud skin of mine tailing sand grains surface attachment parcel, makes mud grain graininess＜0.5mm; Mist droplet granularity is＜0.5mm that spray velocity reaches 0.8～1.6kg/s during said spraying.
In the said step (2); Use in following three kinds of methods any: 1. earlier with solidifying agent and rhombspar mine tailing mix 50～70 seconds; Obtain solidifying agent and rhombspar mine tailing mixed dry material, mixed dry material is mixed ground 50～70 seconds again, spray into vaporific waterside backmost and mixed stone roller 170～200 seconds; 2. earlier the rhombspar mine tailing was mixed stone roller 50～70 seconds, add solidifying agent again and mixed stone roller 50～70 seconds, spray into vaporific waterside backmost and mixed stone roller 170～200 seconds; 3. stone roller mixed 100～130 seconds to rhombspar mine tailing and the solidifying agent that adds together wherein in elder generation, and the limit sprays into vaporific waterside and mixed stone roller 170～200 seconds then.
Send into mould through the compound of mode of vibration after in the said step (3) with mix.
Compound in said step (3) mould during hydrostatic profile, requires hydrostatic profile pressure>=24MPa through the mode moulding of static pressure or dynamic pressure; During dynamic forming, require vibrational frequency>=50Hz, vibration acceleration>=68.6m/s

Solidifying agent can be cement-based solidified dose among the present invention, like the PCSB solidifying agent, also can be to be other solidifying agent of major ingredient with cement clinker and/or pozzolanic material.Solidifying agent can produce the effect of the combined process of mixing effect, polymerization, hydration, chemical action in the rhombspar mine tailing; Various mineral in the rhombspar mine tailing are produced erosion; Cause the mineral crystal surface imperfection; Promote various mineral generation chemical reactions in mineral and the mine tailing that lattice imperfection is arranged in the solidifying agent, the product of solidifying agent mineral self hydration reaction is attached to plane of crystal, constantly growth simultaneously, combines with hydrated product; Parcel mine tailing particle forms membrane structure, grid frame structure.This characteristic has been improved curing performance greatly: increase elasticity, seal intergranular space, increase stability.Specific surface area should reach 400m after the solidifying agent mixing fine grinding
2More than/the kg,, increase activity index to guarantee that particle is tiny.
Facts have proved: when PM for particulate matter＞2mm, common alr mode can make and produce extruding, friction effect between the particle, clod, mud skin under this effect promptly quilt disperseed.And rhombspar mine tailing silt content is high, granularity is tiny, only depends on common alr mode can't reach mud composition dispersive purpose., granularity tiny problem high to the mine tailing silt content; The contriver improves existing mine tailing preparation technology; Discovered before adding water; Earlier white clouds mine tailing and solidifying agent are mixed and grind extremely important (even add solidifying agent before earlier mine tailing mixed grind according to the special domestic animal needs of rhombspar mine tailing), grind the block that makes in the material and scatter (the particularly pug of caking) the mud skin effect of simultaneously the CHARACTERISTICS OF TAILINGS SAND surface being wrapped up through mixing fully; Force CHARACTERISTICS OF TAILINGS SAND to be separated, make its mud grain graininess＜0.5mm with the mud skin.
Further; Add water to doing to mix in back white clouds mine tailing and the solidifying agent through the mode of spraying; Because rhombspar mine tailing granularity is very thin, therefore directly add water or water droplet mix when big, mine tailing will be bonded to clod; Hindered solidifying agent material and the abundant mixing of mine tailing particulate, this will have a strong impact on the mix quality of compound and the performance of moulding product.This situation is directly implemented to solidify if do not handle, will directly have influence on the ultimate compression strength and other correlated performance of solidifying block.Because clod is present in to solidify to be equivalent to solidify in the block and has the cavity in the block, has not only reduced the carrying area that solidifies block, causes intensity to reduce, and can make that also solidifying the block water-intake rate increases, correlated performances such as coefficient of softening reduction worsen, and this is an one of which; The tailings mud interface that exists between the CHARACTERISTICS OF TAILINGS SAND particle greatly reduces the polymerization power between the sand particle, makes that the bonding force between the sand particle is weakened, and causes mechanics and correlated performance to worsen, this be its two; Clod has also influenced the continuous unanimity of block density in solidifying block, under external force, form crack tip easily, cause solidifying the block drag and descend and form crackle, this be its three.For fear of the problems referred to above, the mode that the contriver adopts spraying especially adds water in the material of doing after mixing, and (spray velocity reaches 0.8～1.6kg/s) for mist droplet particle size through the control spraying and spray velocity; Roll simultaneously, mix and stir; Make tiny droplet homodisperse ground mix, get in the material, just make the solidifying agent particle in aquation constantly expose the surface that makes new advances with the mine tailing particle, one side is strengthened solidifying agent aquation effect; The aquation intermediate product depends on mine tailing particle surface lattice defect on the other hand; Constantly growth, accumulation, parcel mine tailing particle forms membrane structure, grid frame structure.Mix, the comprehensive action of stone roller, spray water xi, make the compound activation, eliminate the agglomerate in the compound, it is high further to have overcome the mine tailing silt content, the defective that granularity is tiny is for subsequent handling creates favorable conditions.
Preferably send into mould through the compound after using the vibration cloth with mix; Can guarantee continuity, the smoothness of compound course of conveying; Be convenient to compound uniform distribution further in mould simultaneously; Go into mould compound controllable number, avoid fine particle to adhere to the problem of transfer passage, and then make the tailing-bricks that makes more closely knit.
In pressing process, can use the mode moulding of static pressure or dynamic pressure, but consider the tiny problem of rhombspar tailing-bricks granularity, during hydrostatic profile, require hydrostatic profile pressure>=24MPa; During dynamic forming, require vibrational frequency>=50Hz, vibration acceleration>=68.6m/s
2, through above-mentioned parameter control, improve mobile property of compound and liquefaction effect, further improve the tailing-bricks degree of compactness, ensure the quality of products and stabilize and increase ratio of briquetting.
