Abstract
The invention discloses a kind of magnetization high-bond height grinding consistent ceramic ground section and its manufacturing methods, the component of the ceramic grinding section is made of three kinds of function components, wherein the first function component A be using Nano-sized Alumina Powder, silicon carbide powder, molybdenum disulfide powder, yttria powder, Zirconium dioxide powder, titania powder, SiO 2 powder as raw material low-temperature sintering at ceramic matrix；Second of function component B is to lubricate surface layer using ferroso-ferric oxide, molybdenum disulfide, silver, copper, titanium as the cured magnetization of raw material high-temperature fusion；The third function component C is PVA plastic material；The component relationship of three kinds of compositions are as follows: grid-shaped mutually mix completely with component A securely of component C is combined into kernel, and component B is the modification film layer for being solidificated in core surface by supersonic flame spraying technique spray coating under protection of argon gas.Ceramic grinding segment table layer of the invention lubricates, grinding efficiency is high, binding force is good, abrasion is small, energy consumption is small, grinds more evenly.
Description
Technical field
The present invention relates to cement technical field more particularly to a kind of grinding consistent ceramic grindings of magnetization high-bond height
Section and its manufacturing method.
Background technique
In the prior art, with the rise of cement price, the industry of this field is worth rapid increase, and as technology is sent out
Exhibition, traditional steel abrading-ball are gradually replaced by ceramic grinding ball, but the equipment at present using ceramic ball grinding technique is all inevitable
Ground has two: 1, and since Ceramic Balls self weight is low, extruding force is insufficient under same stirring rate, and ball milling is imitated because caused by
Rate is low, i.e. separate unit ball mill inefficient low output；2, since ceramic grinding ball in the prior art mostly uses coarse sintering technology,
Structure is neither fine and close, again unbalanced, while brittleness is also big, easy fragmentation, thus loss is ground compared to raw steel matter in mechanical milling process
Ball is faster.
In the related patents applied at home, patent " a kind of efficient ball mill with magnetically grinding ball " (application number:
201410816874.4, publication date: 2016-7-20), a kind of technology for having used and having carried out the double-deck grinding with magnet steel ball is disclosed,
But due to using steel ball, hardness is low and quality weight, thus abrasive material loss and electric energy loss is higher and grinding effect is poor,
Magnetize the effect that abrading-ball does not have high self-bonding power and surface lubrication yet simultaneously.
In conclusion needing a kind of surface layer to lubricate on the market, grinding efficiency height, binding force is good, abrasion is small, energy consumption is small, grinds
The ceramic grinding section and its manufacturing method of mill more evenly.
Summary of the invention
To solve drawbacks described above existing in the prior art, the present invention is intended to provide a kind of surface layer lubricates, grinding efficiency is high,
Binding force is good, abrasion is small, energy consumption is small, the magnetization high-bond height of grinding more evenly grinds consistent ceramic ground section and its manufacturer
Method.
To achieve the goals above, the invention adopts the following technical scheme: a kind of grinding of magnetization high-bond height is uniformly made pottery

Compared with prior art, the invention has the following advantages that (1) most crucial technical concept of the invention is how
It will organically be incorporated with antidetonation, lubrication, component and the hard of pooling feature and the extremely stable ceramic matrix of chemical property,
Present invention utilizes ceramic raw material be mixed in a certain proportion it is rear mutually promote molten characteristic, matched a kind of high rigidity, can low temperature
The ceramic matrix formula of sintering, the sintering temperature of low temperature are the bases that the present invention realizes；It then is all superfine powder using raw material
Advantage by it with PVA solution puddling at dirty solution, obtain permeability and wellability, while in sintering by liquefied
PVA increase surface can and internal bond, while having driven intrinsic air (source of Ceramic Balls inner air vent) between powder away, made this
Invention is finer and close；But since the ceramics for squeezing sintering certainly exist coarse, rough surface, the present invention utilizes this
The defects of routine techniques enhances the binding force of the modified film layer in surface layer, at the same by the ratio mixture of 3:1:1 ferroso-ferric oxide with
Silver, copper, titanium in molybdenum disulfide can generate (Ag under high temperature anaerobic environment72Cu28)97Ti3, this be a kind of pair of aluminium oxide especially
It is the fabulous alloy of the aluminium oxide wellability of rough surface, the wellability at 950 DEG C -1000 DEG C is best, this temperature
Degree is exactly mixed-powder during by turning liquid admittedly, significantly enhances the binding force of coating of the present invention and ceramic kernel,
Antibacterial ability (silver) is obtained simultaneously, and certain lubricity is provided；The silver of PVA in kernel, the not formed alloy in surface layer simultaneously
Grain, molybdenum disulfide can provide fabulous surface lubrication effect for the present invention.(2) present invention is exactly magnetic ball there are also a core technology
The ferroso-ferric oxide composition on surface, this composition obviously can provide certain magnetism after magnetizing for mill ball of the invention, by
In using ferroso-ferric oxide rather than kicker magnet neodymium iron boron, thus magnetic intensity of the invention will not be too high, is slightly less than to grind
This guarantees abrading-balls for (performance is by each component weight proportion and magnetize intensity and time realization) of abrading-ball self gravity
Between will not adhere, simultaneously because the interference in magnetic field, itself is in the case where mechanical force direction circulation is constant in routine techniques
Keeping the motion profile of the abrading-ball of certain regular motion also to become, changeable and uncontrollable (abrading-ball is constantly rotating, and magnetic pole constantly becomes
Change, the abrading-ball part abrading-ball that repels each other in part is attracting, destroys the direction that blender brings acting rules power), here it is promote this hair
Bright the reason of capable of grinding more evenly, two abrading-balls of simultaneous grinding contact also must be that magnetism is attracting, be additionally provided one
Fixed extruding force is equally ground thinner using the present invention.(3) present invention is made of three kinds of function components, wherein the first function
Energy component A is with Nano-sized Alumina Powder, silicon carbide powder, molybdenum disulfide powder, yttria powder, titanium dioxide zirconium powder
End, titania powder, SiO 2 powder be raw material low-temperature sintering at ceramic matrix；Second function component B be with
Ferroso-ferric oxide, molybdenum disulfide, silver, copper, titanium are that the cured magnetization of raw material high-temperature fusion lubricates surface layer；The third function component
C is PVA plastic material；Three kinds of composition firm connections, respectively there is effect.(4) the finished product density 3.6g/cm that the present invention obtains3-
3.9g/cm3, the only half of steel material, it is thus possible to effectively economize on electricity, energy conservation, reduce carbon emission；Ceramic hardness is high, wear-resisting
Property is good, and service life is long.Lubricate the present invention finally with surface layer, grinding efficiency is high, binding force is good, abrasion is small, energy consumption
The small, characteristic of grinding more evenly.
