Background technology:
Milltailings is the solid that temporarily can not be utilized or powdered solid fuel that discharge after exploitation, sorting ore.In China, existing more than 10,000 2 thousand, all kinds of milltailings storehouse, the milltailings stored up reaches more than 17,000,000,000 tons to " 12 " end, the mine tailing of particularly fine tailings and flotation mill's discharge, particularly serious to the environmental pollution such as farmland, water source.At present, the average aggregate utilization ratio of mineral processing in China mine tailing is less than 18%, and wherein the utilization ratio of iron and plumbous zinc milltailings is lower.Particularly iron milltailings has become China's industry bulk solid waste that quantum of output is maximum, comprehensive utilization ratio is minimum at present.In China, only 2012 and 2013 the 2 years milltailings such as iron and plumbous zinc generations just reach 16.21 hundred million tons and 16.49 hundred million tons respectively.Along with continuing to increase of Mineral Resources in China exploitation dynamics, milltailings output cumulative year after year, the comprehensive utilization accelerating milltailings is extremely urgent.
Cement, as man-made structures's glue material large now, plays an important role in economic construction, but the resource that a large amount of Wingdale, clay, coal etc. of manufacture of cement consumption is non-renewable, discharge number in the CO of hundred million tons simultaneously
2, SO
2with waste gas and dust such as NOx, resource consumption, the problem such as energy consumption and environmental pollution of its production process are very outstanding.
Prior art, the grinding production technique of cement has ball mill and Vertical Mill two kinds of process forms.For a long time, the building adhesive material production-line technique cement grog grinding such as cement all carries out in ball mill.The building adhesive materials such as the cement of ball milling grinding have good particle characteristics, are conducive to the α-TCP bone cement of the building adhesive materials such as cement, although to be the effective rate of utilization of its energy of ball mill lower for this, only have 2% ~ 5%.But still most production technique still selects the major cause of ball mill.
Vertical Mill have employed increases friction grinding power and repeatedly extrusion technique.Relative ball milling, Vertical Mill energy utilization rate is higher, and this is that grinding system preferentially selects Vertical Mill major cause, but the finish fineness of Vertical Mill is too all neat, and crushing material is rendered as sheet, and particle is mostly polygon.Do not have reasonable grain composition, this is that restriction Vertical Mill broader applications are in the major cause of cement grinding.
Summary of the invention:
The object of the invention is to overcome above-mentioned defect, a kind of production method of novel building glue material is provided, particularly a kind of with rotary kiln clinker, plumbous zinc and iron milltailings waste material be main raw material, the trade waste desulfurization ash etc. that produces with the coal-fired process method that is auxiliary material making novel building glue material.

Described a kind of Action of Superhigh Frequency Vibration grinding and cement granules correcting device technological principle:
Pulverulent material through Vertical Mill process sends into Action of Superhigh Frequency Vibration grinding and cement granules correcting device.Under the strong effect of 200-20000HZ/S high-frequency excitation, material presents and seethes up and down, is in fluidized state (boiling state).Steel ball or steel forging except the strong effect of high-frequency excitation of certainly experiencing, are in and seethe state up and down in Action of Superhigh Frequency Vibration grinding and cement granules correcting device, and the powdery logistics being simultaneously subject to again presenting boiling state drives, and moves upward fast.Move to the steel ball of certain altitude or the steel forging action of gravity due to himself, down drop fast again, move and so forth, produce the compound action power such as strong shearing force, frictional force, impact force and high-frequency vibration, by crushing material, dispersion, refinement and homogenizing effect.Owing to adopting the steel ball identical with ball mill or steel forging as medium, the finish fineness contributing to making up single Vertical Mill is too all neat, and crushing material is rendered as the defect of sheet, just can obtain higher material roundness coefficient with very low power consumption.
The invention has the advantages that:
1, compared with conventional bead mill, mill efficiency is that geometry level improves.
Conventional bead mill principle of work utilizes the steel ball in rotary barrel or steel forging to the continuous impact of material and grinding, makes the final grinding of material become qualified product.Due to the effect of centrifugal force and frictional force, steel ball or steel forging are rotated together along with grinding mill barrel.The movement locus of any one deck steel ball or steel forging is all take body centre as the circumferential motion in the center of circle.After steel ball in ball mill or steel forging are rotated and be thus lifted to certain altitude together with cylindrical shell, the centrifugal force because of grinding element is less than the banks of gravity, and now, grinding element leaves barrel and does parabolic motion realization to the pulverizing of material in mill and grinding.In this process, steel ball or the motion done of steel forging major part are all be not intended to consume, and the effective rate of utilization of Here it is why its energy of ball mill is lower, only has the reason of 2% ~ 5%.
On the other hand, when the actual speed of ball mill reaches quick passage critical speed or is greater than quick passage critical speed, in mill, the running orbit of steel ball or steel forging is the circumferential motion that against cylindrical shell, there is not separation point and point of contact, namely shock point is not had, do not have the effect of impact grinding material: when the actual motion speed of ball mill is too small, ball mill does not have ability to take steel ball or steel forging to reasonable altitudes, the movement locus that leaves cannot be formed to impact material, and the movement locus entirely rushing down state can only be formed, well can not play shock action.Therefore, the general rotating speed of ball mill only about 18r/min.
Action of Superhigh Frequency Vibration grinding and cement granules correcting device vibrational frequency are up to 200-20000HZ/S; Materials inside, by this strong exciting effect, is seethed up and down, is in fluidized state (boiling state).Steel ball or steel forging except the strong effect of high-frequency excitation of certainly experiencing, are in and seethe state up and down in Action of Superhigh Frequency Vibration grinding and cement granules correcting device, and the powdery logistics being simultaneously subject to again presenting boiling state drives, and moves upward fast.Move to the steel ball of certain altitude or the steel forging action of gravity due to himself, down drop fast again, move and so forth, produce the compound action power such as strong shearing force, frictional force, impact force and high-frequency vibration, by crushing material, dispersion, refinement and homogenizing effect.Owing to adopting the steel ball identical with ball mill or steel forging as medium, the finish fineness contributing to making up single Vertical Mill is too all neat, and crushing material is rendered as the defect of sheet, just can obtain higher material roundness coefficient with very low power consumption.
On the other hand, because steel ball or steel forging are suspended in material compound action power such as making quick, strong shearing force, frictional force, impact force and high-frequency vibration, all the time by crushing material, dispersion, refinement.Do not produce and be not intended to consume, material grinding per unit area yield energy consumption declines 30% ~ 70%.
2, owing to adopting the steel ball identical with ball mill or steel forging as medium, the finish fineness contributing to making up single Vertical Mill is too all neat, crushing material is rendered as the defect of sheet, its finished particle presents the circle identical with ball milling grinding or sub-circular, and size distribution and pattern are conducive to the α-TCP bone cement of the building adhesive materials such as cement.The fine powder content being less than 30 μm in cement increases by 10%, and concrete scroll is more reasonable, and intensity increases by 3 ~ 5MPa.
3, the glue material particle such as cement that traditional way is produced is drawn mutually by Van der Waals force because surface energy is not enough and forms small cluster of grains.In ready mixed concrete, when cement granules group contacts with water, the capillary force produced after the hydration reaction of top layer is three times of Van der Waals force.It is case hardening that they make the cement granules after hydration reaction roll into a ball, thus hindering water, to enter cluster of grains inner and the most tiny, is also the cement granules generation hydration reaction having bounding force most.Therefore these cement granules cannot play its bonding force.Cement granules after aquation is rolled into a ball just as one possesses elasticity, plasticity, the miniature object of viscosity and colloidality, have impact on the continuation aquation of cement fine particle.
The present invention utilizes ultra high frequency to vibrate, and it makes cement granules group become a resonating body, thus cement granules group is split into single particle, and the speed of growth of its specific surface area and its crystalline fiber structures is all significantly improved.Novel building glue material prepared by application the present invention, the cement products of production same levels, rotary kiln clinker consumption can save more than 25%.
4, after the plumbous zinc of the present invention and milling beneficiation tailing waste material adopt and dry classification≤0.080mm part is direct as cement mixture, saves unnecessary grinding pow consumption.
5, the invention provides a kind of production method of novel building glue material, its material is prepared respectively, and a point stock is put, and just can be realized production and the packaging of different intensity grades building adhesive material by metering, mixing, market readjustment flexibly and fast.
6, the invention provides a kind of production method of novel building glue material, plumbous zinc and the oven dry of iron milltailings waste material, classification are used, particle diameter > 0.080mm part is used as concrete medium sand; ≤ 0.080mm part, as cement mixture, realizes plumbous zinc and the efficient whole synthesis utilization of milling beneficiation tailing waste material.
