Description
Technical field
The present invention relates to raw material processing technical field, the grinding method of a kind of shrend carbide slag.
Background technology
In order to reclaim the titanium resource in titanium-containing blast furnace slag, climb steel and grasped a kind of preparation TiCl from blast furnace slag4New Techniques,
It is i.e. " steel climbing high slag high temperature cabonization low temperature selective chlorination " technique.This technique be in electric furnace with carbonaceous reducing agent to blast furnace
Slag carries out high temperature reduction carbonization treatment, and titanium is reduced to titanium carbide (TiC), and the blast furnace slag after carbonization treatment is referred to as carbide slag, uses
I.e. obtaining shrend carbide slag after high pressure water impact hot melt carbide slag, shrend carbide slag selects as next step low temperature after ball mill grinding
The primary raw material of chloridization process uses.
Low temperature selective chlorination technological requirement carbide slag particle size range is the harshest, it is desirable to particle size range is 0.074mm～0.178mm.
And shrend carbide slag has rough surface porous, quality is the most crisp, the physical property such as is easily broken, with Slow cooling in atmosphere
The character of carbide slag is different.Use the carbide slag ball mill crushing process grinding shrend carbide slag of slow cooling in air, there is steel ball and damage
Consumption is big, mill efficiency is low, the undesirable problem of granularity after grinding.Therefore, by ball mill, shrend carbide slag is carried out powder
Mill, selecting suitable ball mill steel ball and grinding method is the key point controlling carbide slag particle size range.
Summary of the invention
The technical problem to be solved is to provide the method for the grinding of a kind of shrend carbide slag, solves to use slow cooling in air
Carbide slag ball mill grinding process grinding shrend carbide slag, have that steel ball loss is big, mill efficiency is low, granularity is not inconsistent after grinding
Close the problem required.
The present invention solves the grinding method of above-mentioned technical problem the technical scheme is that shrend carbide slag, by shrend carbide slag
Add ball mill feed bin, ground by abrasive body and prepare carbide slag powder；Described abrasive body is made up of the steel ball of two kinds of particle diameters of size,
Small particle steel ball weight is the 60%～75% of abrasive body weight, and the diameter of the steel ball of described two kinds of particle diameters of size isAnd the difference of the diameter of two kinds of steel balls is not less than 20mm.
Further: the difference of the diameter of the steel ball of described two kinds of particle diameters of size is 30mm～50mm.
Further: described small particle steel ball weight is the 65%～70% of abrasive body weight.
Further: big particle diameter steel ball and small particle steel ball are middle evanohm steel ball or high-chromium alloy steel ball.Big particle diameter steel ball and
Small particle steel ball can be selected for high-chromium alloy steel ball, it is contemplated that shrend carbide slag rough surface porous, quality is the most crisp, be easily broken
Physical property, and the cost of abrasive body, even if evanohm steel ball can meet technological requirement in Xuan Yonging.
Further: the abrasive body filling rate in described ball mill is 33%～38%.
Moreover: the abrasive body filling rate in described ball mill is 36%.
The invention has the beneficial effects as follows: the first, this method only need to pass through abrasive body to shrend carbonization in ball mill a feed bin
Slag is ground, it is not necessary to first pulverizes and grinds, and production process is simpler easily-controllable；The second, shrend is ground by this method
The powder particles that carbide slag obtains is uniform and stable, meets low temperature selective chlorination technique high to carbide slag powder particle size desired ratio,
Meet the low temperature selective chlorination technique granularity requirements to shrend carbide slag grinding；3rd, the proportion of goods damageds of abrasive body steel ball reduce,
Save steel ball usage amount, and reduced ball mill unit power consumption, reduce production cost.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the invention will be further described.
The present invention is the grinding method of a kind of shrend carbide slag, is directly added in the feed bin of ball mill by shrend carbide slag, at one
Feed bin is ground by abrasive body and directly prepares carbide slag powder；Abrasive body in feed bin is the steel ball of two kinds of different particle diameters, two
Kind of steel ball a diameter ofBetween two values arbitrarily not waited, and the difference of the diameter of satisfied two kinds of steel balls
Value is not less than 20mm, and such as small particle steel ball size isThe biggest particle diameter steel ball size isIn
Any value；The biggest particle diameter steel ball size isThen small particle steel ball size isIn appoint
One numerical value；Small particle steel ball weight is the 60%～75% of abrasive body weight, and remaining phase should be big particle diameter steel ball；In ball mill
Steel ball pack completeness is 33%～38%, preferably 36%.
Described big particle diameter steel ball and small particle steel ball are evanohm material, for example, middle evanohm or high-chromium alloy.In view of shrend
The physical propertys such as carbide slag rough surface porous, quality is the most crisp, be easily broken, and the cost of abrasive body, though chromium in Xuan Yonging
Alloy steel ball can meet technological requirement.
Below in conjunction with 3 specific embodiments, the grinding method of the shrend carbide slag of the present invention is specifically described, wherein
The diameter of the steel ball of two kinds of particle diameters of size is respectivelyWithThe weight of two kinds of steel balls of size accounts for grinding body weight respectively
The ratio of amount is as shown in table 1.
The steel ball weight ratio of each embodiment of table 1
By the steel ball grating of table 1 illustrated embodiment, after ball mill grinds, the grain size analysis of gained carbide slag is shown in Table 2.
Table 2 carbide slag powder particles is analyzed
The result analyzed from table 2 carbide slag powder particles is it can be seen that above-described embodiment 1, embodiment 2, embodiment 3 are ground prepared
Carbide slag powder weight accounting in the range of 0.074mm～0.178mm be respectively 89.7%, 90.3% and 88.9%, these three
In embodiment, carbide slag powder meets the ratio of low temperature selective chlorination technological requirement and is above 85%, meets technological requirement.
Using the carbide slag ball mill crushing process grinding shrend carbide slag of slow cooling in air, ball mill runs 8h～10h every day, and half
After individual month, the rupture rate of steel ball is about 2%, uses the method for the invention to be ground shrend carbide slag, and ball mill runs every day
8h～10h, the basic crack-free of steel ball after two weeks, reduce the wear extent of steel ball, improve the service life of steel ball, make production
Cost declines to a great extent.It addition, the shrend carbide slag powder particles ground by this method is uniform and stable, production process is without first breaking
Broken grind again, simple to operate easily-controllable.
