Abstract
A basalt volcanic ash micropowder is prepared by pulverizing natural gas porous basalt into powder with fineness less than or equal to 80 μm, screen residue of 6.6%, Loss on ignition less than or equal to 1.34%, and SO3The content is less than or equal to 0.15 percent; the volcanic ash micro powder with the 28-day compressive strength ratio of more than or equal to 69.54 percent can be used for producing cement mixing materials of ordinary portland cement and concrete admixtures, and can reduce the cost and improve the benefit on the premise of ensuring the quality.
Description
Technical field
The invention belongs to building material field, particularly a kind of basalt volcanic ash micro mist.
Background technology
When in manufacture of cement, grinding cement usually with Portland clinker, add a part of mixing material, not only can increase output and reduce cost, and can also improve the stability of grog, improve the tensile strength of cement, physical behaviors such as water resisting property, compactness and water-permeable are to satisfy in the engineering construction some special technical requirements to cement.As the pozzolana mixed material of fusion 20 ~ 50%, then can produce trass cement.And pozzolana mixed material can be divided into a natural class as: volcanic ash, float stone, tuff, diatomite etc. and artificial make a class as: burn clay, cinder, siliceous slag, bastard coal rock ballast and flyash etc.When using concrete in these external various engineering constructions,, can on the basis of ensuring the quality of products, save cement reduction construction costs with volcanic ash and the moiety of a certain proportion of ordinary Portland cement fusion as jelling agent.In actual use, it is more very different than characteristics such as, strong rubber compare that ultimate compression strength behind the concrete, strong lime are advanced in all kinds of pozzuolanic quality, activity and fusion, as when mixing 30% flyash, every technical indicator descends just more.Therefore in order to guarantee that technical indicator reaches standard, when guaranteeing construction quality, can save cement to greatest extent again, reduce cost, requirement can provide a kind of better volcanic ash adulterant or cement clinker mixing material.
The a large amount of red-hot magma of the volcanic eruption face of land that gushes out forms multiple volcanized rock after the condensation, pore shape basalt is wherein a kind of, and its essential mineral composition is peridotites, plagioclase, pyroxene, ilmenite, and its chemical ingredients is with silicon oxide sio

Summary of the invention
The purpose of this invention is to provide a kind of basalt volcanic ash micro mist, characteristic such as utilize pore shape basalt mineral composition unanimity, quality is even, material activity is good is processed into basalt volcanic ash micro mist through novel milling equipment.
The basaltic chemical ingredients of pore shape that the present invention adopts is quality % as table 1:(unit)
| Loss | SiO 2 | Al 2O 3 | Fe 2O 3 | CaO | MgO | SO 3 | ∑ |
| 2.20 | 56.1 | 17.77 | 8.10 | 6.67 | 3.71 | 0.25 | 94.80 |
The kind basalt volcanic ash micro mist that the present invention proposes is processed into by following manufacture craft flow process:
Volcanized rock mining → starting material fragmentation → chemical examination classification → electronic proportioning → drying materials → work in-process warehouse-in → additive → work in-process homogenizing → superfine pulverizing → efficient vortex selects powder → finished product collection → elementary test → finished product homogenizing → examination and test of products → packing of product to put in storage → dispatch from the factory.
Concrete operations are achieved in that
Adopt three-dimensional perron exploitation basalt ore, through three grades of rubbles that are broken for below the 30mm, per hour SiO in the raw material is chemically examined in sampling observation

3What enter the semifinished product warehouse of three grades of branches respectively; Make three grades of ores in the semifinished product warehouse enter dryer by electronic proportioning equipment by the index collocation of top table 1, dry to the ore contained humidity and be lower than 1%, enter homogenizing storehouse then again, draw samples chemical examination in the storehouse, add the different chemical element by result of laboratory test and make it up to standard, and abundant homogenizing; Work in-process after homogenizing input ball mill is worn into micro mist, after selecting powder, efficient vortex enters stockyard again, to the laboratory examination of warehouse-in finished product, for making the constant product quality unanimity, by falling the pneumatic homogenizing in storehouse and bottom of the reservior, make its abundant mixing, then product is carried out by the strict check of standard, the packing warehouse-in dispatches from the factory.
Embodiment
Be described further below in conjunction with embodiment: open-air three-dimensional exploitated ore is carried out in the basalt mining area in stone Shanxi portion Tengchong industrial park planned range, after adopting 960 * 3800 type oscillating feeders → 600 * 900 type jaw crushers → three grades of broken circulation technologies processing of 1210 type impact breakers, carry out sub-sieve with 1548 type vibratory screening apparatuss, particle diameter returns 1210 type impact breakers → 1548 vibratory screening apparatuss greater than the 30mm material and carries out sub-sieve; Per hour SiO in the ore is chemically examined in sampling in shattering process
