Description
Technical field
The present invention relates to cement manufacture field more particularly to a kind of cement ball mill ceramic grinding ball preparation methods.
Background technology
Cement ball mill mill ball is ball mill equipment grinding material medium, by between ball mill grinding ball, mill ball
Between material, the collision friction between mill ball and liner plate generates ablation, so as to which the grain size of material further be reduced.
Mill ball target is mostly cement, coal, ore, cinder etc., especially cement industry, and fineness greatly decides product
Performance.Therefore, mill ball hardness when in use and wearability are one of principal elements for influencing ball milling shaping effect,
The friction occurred between mill ball and abrasive material, mill ball and mill section in process of lapping is inevitable, therefore, also requires mill ball
There is high hardness.In the prior art, the material of cement ball mill mill ball is mostly tool steel or high carbon stainless steel, material phase
Worn material between larger between mutually, surface is easily degraded, and the proportion of goods damageds are big, is replaced soon；Meanwhile the mill ball quality of steel is big, work
Power consumption is high when making, and the carbon emission brought is big, influences energy efficiency and environmental protection；In addition, steel abrading-ball is yielding, easy to stick each other
Connection influences the consistency of cement average particle size, and strength of cement fluctuation is big, irregular deformation easily occurs for the later stage；Common steel at present
Abrading-ball is martensite type abrading-ball, and metallographic structure will be undergone phase transition at 250 DEG C or more, and mechanical performance declines rapidly, simultaneously
Also more yielding, adhesion, therefore, it is difficult to adapt to for a long time, high intensity grind work；Steel material is easily by a variety of salt, acid, alkali
Corrosion, itself can also corrode under oxidation+water environment, and loss is big, while influence prepares the degree of purity of cement.
In the related patents applied at home, patent《A kind of preparation process of ball mill high hardness wear-resisting abrasive body》
（Application number：201410374668.2 publication date：2014-10-15）, disclose a kind of preparation of high hardness high toughness wear body
Method, adds the properties that the functions auxiliary material such as molybdenum-iron promotes abrading-ball into conventional steel abrading-ball, but steel abrading-ball in itself intolerant to
Erosion, since a variety of alloying elements add, the corrosion resistance of abrading-ball can also decline；In addition, it is still martensite type steel grade, intolerant to height
Temperature.Patent《A kind of corrosion-resistant high hardness high toughness ball mill abrasive body》（Application number：201410376993.2 publication date：
2014-10-08）, a kind of abrasive body for equally employing ceramics as raw material, but its complicated component are disclosed, the patent is not
Open preparation method is realized difficult；The patent contains the expensive ingredient such as rare earth ferrosilicon alloy, cubic boron nitride, economy simultaneously
Difference；Although in addition the addition of more silicon carbide is the toughness for improving abrasive body to a certain degree, mill ball hardness is resulted in
Decline and structure it is loose.
Invention content
In view of the above defects of the prior art, the present invention is intended to provide a kind of high rigidity, high temperature resistant, it is corrosion-resistant,
Operating power consumption is low, material consumption is low, binding force is good, jolt capacity is strong, shock resistance Ulva Pertusa, the cement fineness of production and later strength are high
Cement ball mill ceramic grinding ball.
To achieve these goals, the present invention uses following technical scheme：A kind of cement ball mill ceramic grinding ball,
Ingredient is by weight percentage containing aluminium oxide 92-95%, di-iron trioxide 0.5-2%, kaolin 0.8-3%, silicon carbide 0.2-
2%th, titanium dioxide 1.5-2%, titanium carbide 0.8-1%, molybdenum disulfide 0.3-2%.
Above-mentioned cement ball mill ceramic grinding ball, is solid sphere, granularity be preferably 10mm, 15mm, 20mm,
One or more combinations in 25mm, 30mm, 35mm, 40mm, 50mm, 60mm, 70mm, 80mm.
Above-mentioned cement ball mill ceramic grinding ball, wherein：There is similar football surface block on the solid sphere surface
Rule protrusion；
Above-mentioned cement ball mill ceramic grinding ball, wherein：There is the item of similar watermelon lines on the solid sphere surface
Shape protrusion；
Above-mentioned cement ball mill ceramic grinding ball, wherein：The solid sphere surface is smooth, has the cap of similar cap
Eaves.
The above-mentioned cement ball mill preparation method of ceramic grinding ball, includes the following steps：
(a) dispensing：All the components are taken by weight percentage, are mixed and stirred for uniformly, mixed material being made；It is configured simultaneously

Compared with the prior art, the present invention is as a result of said program, and finished product density obtained is 3.6-3.9, only
The half of steel material, it is thus possible to effectively economize on electricity, energy saving, reduction carbon emission；Ceramic hardness is high, and wearability is good, service life
It is long；A certain proportion of di-iron trioxide is added, finished product is made while abrading-ball mechanical performance is improved in brownish red or sepia,
The white of ceramic industry is different from, identification is high, is not easy to obscure；Hardness is high, indeformable, can precisely control finished ground cement
Fineness, so as to which cement be controlled to reach normal consistency water requirement, and then ensured in the case where not influencing cement intensity early period
The later strength of cement, while same batch of finished ground cement fineness uniformity, granule-morphology preparing are reasonable, cement performance is more steady
Calmly, scattered error is small, and strength of cement fluctuation is small, irregular deformation will not occur for the later stage, conducive to safety and quality；Material consumption is low, and abrasion are only
Less than 2/10000ths, persistently, the replacement cycle it is long, while also reduce use cost, good economy performance；Resistance to various corrosion, object itself
It consumes small and will not mix impurity, the finished ground cement high purity prepared into finished ground cement；High temperature resistant will not be sent out at high temperature
Raw softening, deformation and adhesion are suitable for long-time, the operating mode of high intensity；The addition of a small amount of molybdenum disulfide and silicon carbide is not
Its binding force is improved under the premise of significantly affecting ceramic grinding ball hardness, binding force is good, jolt capacity is strong, shock resistance antiknock
Shake, makes that it is non-breakable in impact, it is scarce to collapse, and practicability is good.
Meanwhile compared with the prior art, the preparation method of the cement ball mill ceramic grinding ball in the present invention, due to adopting
With preliminary grinding, fine grinding, mix grinding three process ball milling and step-sizing, make slurry fineness uniformity；Carry out iron removal step, energy
The impurity in slurry is effectively removed, improves ceramic degree of purity；Because aluminium oxide ceramics powder category non-plastic raw material, in order to suppress
Molding needs need to add in bonding agent, therefore add PVA solution in mist projection granulating, and it is to inhibit to steep to add in antifoaming agent
Foam generates, and improves production capacity, reduces production cost；The aging process of feed bin can effectively remove the moisture in pelletizing；Die mould adds
Work process is molded powder；Parting sand is sprinkled into high temperature sintering process, product adhesion is can effectively prevent, makes burnt product and high temperature
Saggar can be easily separated；Clear powder polishing process removes the parting sand and burr that are adhered in sintering process, makes product bright and clean；Last
Drying process makes product that manufacture index be fully achieved.
