Abstract
The present invention discloses a kind of method that Production of Ceramics raw material is prepared using granite waste material, belongs to granite waste material utilization technology field.It is included granite waste material classification grinding and then the stone slurry for adding water to be ground into specific grain composition;Stone slurry is subjected to preliminary magnetic separation in the magnetic separator of the Gauss field strength of 15000 Gauss field strength~16000;Then, it is 20wt%~30wt% to be diluted to solid content, then carries out further magnetic separation in the magnetic separator of the Gauss field strength of 50000 Gauss field strength~60000;By the dehydration of stone slurry, the drying Jing Guo further magnetic separation.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 sufficiently utilize magnetic separator specifically high-strength magnetic field as far as possible, improve the magnetic force to iron, remove more than 95% iron, then by diluting and reusing magnetic separator, specifically high-strength magnetic field is removed to residual iron again, so as to reduce the iron content in end-product.
Description
Technical field
The invention belongs to granite waste material utilization technology field, and in particular to one kind prepares pottery using granite waste material
The method of porcelain production raw material.
Background technology
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.
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, is further driven to granite exploitation, processing.
And traditional mode of production is used in being exploited due to granite resource, the lumber recovery of stone material only has 25% or so, and production technique falls
Cause the generation of a large amount of granite waste materials afterwards.And contain in the granite waste material:Potassium K2O7-10%, sodium Na2O4-6%, aluminium
AL2O316-18%, iron 6-9%, biotite 3-6%, silicon SiO260-72%, calcium 1.45%, also a small amount of element more than 30 are planted.Such as
Granite waste material is not used but arbitrarily abandons it and stack by fruit, not only causes serious environmental pollution, also result in
The serious waste of resource.
At present, people begin attempt to granite waste material being made up raw material --- the potassium sodium of Production of Ceramics of recycling
Aluminium stone flour.However, although raw material --- the potassium sodium aluminium stone of Production of Ceramics can be made up in granite waste material of recycling really
Powder, but its recycling cost is too high, iron content is too high in end-product potassium sodium aluminium stone flour, causes its quality not excellent enough, from
And influence the popularization and application of granite waste material recycling.
The content of the invention
The invention provides a kind of method that Production of Ceramics raw material is prepared using granite waste material, this method can solve
The problem of iron residual content is too high in gained end-product be present during existing granite waste material recycling.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:
It comprises the following steps:
A, granite waste material is dry grinded into a diameter of 40mm~60mm middle stone pellet;
B, the gravelstone pellet by the middle stone pellet dry grinding into 20mm~40mm;
C, the gravelstone pellet is dry grinded into 5mm~15mm sand grains;
D, 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%;
E, 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;
F, 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;
G, by the dehydration of stone slurry, the drying Jing Guo further magnetic separation.
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 the iron content in end-product.
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.
