Abstract
The present invention discloses a kind of method that ceramics are produced using granite waste material, belongs to granite waste material utilization technology field.It is included granite waste material graded crushing, and then plus water is ground into the stone slurry of specific grain composition；Stone is starched by preliminary magnetic separation to remove more than 95% iron and the metallics such as 70%~90% biotite and magnesium, silicon, titanium, niobium and objectionable impurities in stone slurry；Then dilute again and carry out further magnetic separation；Stone is starched and mixed with feldspar, sand, clay, and is milled to certain fineness, powder is then made；Finally powder is put into grinding tool and is pressed into base substrate, is then fired.It is too high that iron content in obtained potassium sodium aluminium stone flour produced using prior art instant invention overcomes granite waste material, it is not used to production ceramics or even if can be used for production ceramics, but the quality of the ceramic product obtained by it is generally poor, so as to influence granite dead meal recycling popularization and application the problem of.
Description
Technical field
The invention belongs to granite waste material utilization technology field, and in particular to one kind utilizes granite waste material production pottery
The method of porcelain.
Background technology
Granite plates are a kind of high-quality construction materials, be largely used to high-grade, luxurious building, construct building by laying bricks or stones and filling
Decorations.With the development of modern architecture, the demand of granite plates is increased sharply, the exploitation of granite is further driven to, adds
Work.And substantial amounts of dead meal is generated in the process of granite, substantial amounts of silicon, potassium feldspar, sodium length are contained in stone slurry
The nonmetallic minerals such as stone, aluminum oxide, it is upper number raw material of production ceramics.However, generally granite processing factory is to starch the stone
Directly dumped as useless slurry, so do and not only cause pollution to local environment, also result in the serious waste of resource.
Ceramics are the common names using clay as the product of primary raw material such as pottery, stoneware, porcelain, two so-called potteries and porcelain
（Ceramics）There is three kinds of daily, artistic and architectural faience etc..The traditional concept of ceramics refers to all with nothings such as clay, feldspar, quartz
Machine nonmetallic mineral is the artificial industrial products of raw material.It includes the mixture by clay or containing clay through being kneaded, and shaping, forges
Burn and manufactured various products.By most coarse earthenware its scope is belonged to most fine fine pottery and porcelain.
At present, people begin attempt to granite dead meal potassium sodium aluminium stone flour is made by recycling, and for producing
Ceramics.However, the recycling cost of existing granite dead meal is too high, iron content is too high in product potassium sodium aluminium stone flour, can not
For producing ceramics or even if can be used for production ceramics, but the quality of the ceramic product obtained by it is generally poor, from
And influence the popularization and application of granite dead meal recycling.
The content of the invention
The invention provides a kind of method that ceramics are produced using granite waste material, this method can solve existing granite
The problem of iron residual content is too high in gained end-product in waste recovery processing procedure be present.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
It comprises the following steps：
A, first granite waste material is dry grinded into a diameter of 40mm~60mm middle stone pellet, then will the middle stone pellet dry grind into
20mm~40mm gravelstone pellet, then the gravelstone pellet is dry grinded into 5mm~15mm sand grains again；
B, water is added to be ground into stone slurry the sand grains, the solid particle grading of the stone slurry is：
A diameter of 1mm~1.5mm：20%~30%；
A diameter of 2mm~3mm：50%~60%；
A diameter of more than 3mm：≤3%；
C, the stone is starched and carries out preliminary magnetic separation in the magnetic separator of the Gauss field strength of 15000 Gauss field strength~16000 to remove
More than 95% iron and the metallics such as 70%~90% biotite and magnesium, silicon, titanium, niobium and objectionable impurities in stone slurry；
D, stone slurry will be obtained by preliminary magnetic separation, and to be diluted to solid content be 20wt%~30wt%, then 50000 Gauss field strength~
Further magnetic separation is carried out in the magnetic separator of 60000 Gauss field strength；
E, by weight, by the stone slurry of 15 parts~25 parts further magnetic separation of process and 30 parts~45 parts feldspars, 25 parts~35 parts
Sand, the mixing of 15 parts~20 parts clays, and be put into and the fineness of gained mud is milled in ball mill is tailed over for 250 mesh sieves 0.8%
In the range of~1.2%；
F, obtained mud is sprayed into the powder that water content is 6.0%~7.0% using spray drying tower；
G, gained powder is put into grinding tool and is pressed into base substrate, be then fired.
In above-mentioned technical proposal, more specifically technical scheme is：The magnetic separator and F-step of the preliminary magnetic separation of E steps enter one
The magnetic separator for walking magnetic separation is wet type electromagnetic magnetic separator.
Due to being had the advantages that using above-mentioned technical proposal, the present invention：
1st, the present invention is matched somebody with somebody by the way that granite waste material first to be crushed to, is ground into the particle pole of particular size, so as to as sufficient as possible
Using the specific high-strength magnetic field of magnetic separator, the magnetic force to iron is improved, removes more than 95% iron, then again by dilution and again
Using magnetic separator, specifically high-strength magnetic field is removed to residual iron, so as to reduce intermediate product --- in granite waste material stone slurry
Iron content, improve end-product ceramics quality.
2nd, the diameter that the present invention is crushed by the way that every one-level is classified and limited to granite waste material, not only reduces granite
The broken difficulty of waste material, also reduce the magnetic force between particle after granite waste material crushes, avoid being bonded between particle, be beneficial to
Follow-up deferrization process, reduce the residual quantity of iron.
3rd, the present invention selects wet type electromagnetic magnetic separator, can effectively avoid because dust occurs in short grained granite waste material
Fly upward and influence magnetic separation effect.
Embodiment：
Below in conjunction with instantiation, the invention will be further described：
