The invention provides a pellet binder and an adding device and an adding method thereof. Before adding, according to the weight of the pellet mixture conveyed by the material belt in unit time and unit length, the weight of the binder to be added and the binder distribution amount on the electronic belt scale are calculated correspondingly; and adding the binder into the pellet mixture by the electronic belt scale according to the weight of the binder to be conveyed and the proportion of 4-7% by weight. The invention has sufficient raw material sources, the auxiliary raw materials do not contain harmful components such as ash, silicon and the like, the total iron is not reduced, the bentonite binder can be replaced or partially replaced, the grade of the finished ore is improved by more than 1.0 percent, and the content of SiO2 is reduced by 0.8 percent. The preparation method is simple, is suitable for large-scale production application, and can meet the production requirements of various inferior concentrates.
Description
Technical field
The invention belongs to the sinter additives field, relate in particular to a kind of sticker and adding apparatus and adding method that is used for the agglomerates of sintered pellets compound.
Background technology
In sintered balls nodulizing production process, when preparing, green-ball need add the wilkinite of some amount, and wilkinite has higher water-absorbent, can regulate the raw material moisture of pellet, stablizes the pelletizing operation, improves green-ball and finished ball intensity.But bentonitic staple is SiO2, adds wilkinite in the green-ball pellet ferrous grade is reduced, and influences furnace processor and coke ratio.In addition,, can between iron oxide particle, form cross structure during pellet roasting, stop up the passage that gets into internal voids, cause the decline of pellet ore reduction property, increase the energy consumption when smelting because the wilkinite fusing point is higher.
Under the pellet formation normal circumstances, the bentonitic consumption of pellet per ton is at 20～25 ㎏, and for the sintering plant of producing 1000 ten thousand tons throughput per year, annual bentonitic demand is up to 20～250,000 tons.Only transportation cost just reaches 1600～2,000 ten thousand yuan.And the SiO in the wilkinite
2In the pellet roasting process, can not evaporate again, remain in the pellet, pellet grade is reduced.At present domestic pellet grade is generally about 65.5%, and SiO wherein
2More than 5.0%.
Summary of the invention
The object of the invention aims to provide a kind of simple, is suitable for big production application, can reduce the wilkinite proportioning, improves pellet grade, helps the blast furnace raising the output and falls burnt pellet binder and adding apparatus and adding method.
For this reason, the technical solution that the present invention taked is:
A kind of pellet binder is characterized in that, the raw material weight degree is:
Chrysanthemum root 58-63%; Xylo-Mucine 29-31%; Smectite 8-15%.
A kind of adding apparatus of above-mentioned pellet binder is characterized in that, by adhesive of groove, belted electronic balance and meet flitch and form; The belted electronic balance above-head of being located at material belt top is provided with adhesive of groove, and the belted electronic balance tail end is equipped with one and meets flitch.
A kind of adding method of using above-mentioned pellet binder and adding apparatus is characterized in that, specifically adding method is:
With the sticker powder that the prepares adhesive of groove of packing into, according to the pelletizing compound weight of being carried on material belt unit time, the unit length, corresponding calculate should with addition of weight of binder and the sticker abundance on the belted electronic balance; Open adhesive of groove, belted electronic balance according to the ratio of weight percent 4-7%, adds sticker according to the weight of binder that should carry on the unit time of setting, the unit length in the pelletizing compound; For sticker is fully contacted and uniform distribution with the pelletizing compound, the sticker of carrying on the belted electronic balance drops on earlier meets on the flitch, will be scattered in above the pelletizing compound of material belt conveying through the sticker of meeting after flitch is turned back, and realizes with addition of process.
Main effect of the present invention and effect are:
Pellet binder of the present invention is a kind of organic binder bond, and main raw material is a kind of microphyll-chrysanthemum root, though be wild, also can plant after the enlargement of scale, so sufficient raw of the present invention and guaranteed.The auxiliary material CMC 99.5 does not contain ash content, silicon etc. to the deleterious element of blast furnace, helps blast furnace production direct motion.
Sticker of the present invention is to form alternative traditional bentonite adhesive by organic polymer remodeling.Nontoxic, under 690 ℃ of conditions, can decompose fully, compare with organobentonite, because of not containing objectionable constituent such as ash content, silicon, do not reduce full iron, therefore have good effect and wide market application prospect.
Use pellet binder of the present invention to substitute or the alternative bentonite adhesive of part, can reduce bentonitic consumption significantly.The consumption that makes bentonite adhesive is by original about 2.5%, is reduced to about 0.5% even can not use wilkinite fully, helps protecting Mineral resources.
Use the present invention's pellet binder, can improve finished product ore deposit grade (TFe) more than 1.0%, SiO
2Content reduces by 0.8%.And pellet binder preparation method of the present invention is simple, need not special processing, as long as the siccative of pulverizing is mixed.It is convenient to operation with addition of mode, is particularly suitable for big production application, and low to the working conditions requirement, can satisfy the production requirement of various concentrate inferior.
