Abstract
This invention discloses a modified powder grinding aid. The grinding aid utilizes furnace slag as the carrier, and the doping amount is decreased to 0.2% from present 0.8% doping amount. It is proven that the grinding aid can increase the doping amount of mixed materials in composite cement by more than 10%, and increase drilling meters per hour by 10%. Besides, the doping cost of the grinding aid per ton cement is only 1.5 yen, and Cl- content in cement is much lower than 0.06%.
Description
Technical field
The present invention is a kind of novel powder enhanced type grinding aids that adds in cement pulverizing course
Technical background
As everyone knows, cement is the high a kind of product of energy consumption, and grog coal consumption, cement grinding power consumption are two the highest key links of energy consumption in the manufacture of cement.Therefore reducing the grog volume and improve the cement grinding mill unit-hour output in cement pulverizing course is the key technique that reduces the cement products energy consumption index.Country will use grinding aid to classify the major technique measure that cement industry cuts down the consumption of energy as in cement, and domestic most cement production enterprises have added grinding aid in process of production.The grinding aid product that has powder and two kinds of forms of liquid in the market.Wherein powder does not have the grinding aid effect basically based on enhancing, and addition content is basically about 0.8%; Liquid is based on grinding aid, and volume is about 0.035%.No matter mixing cost, spares which kind of its ton of grinding aid cement more than 3 yuan.
How with grinding aid with strengthen two kinds of usefulness and effectively combine, improve grinding aid to greatest extent and mix effect, reduce the ton cement grinding aid and add a cost, the economical effectiveness that improves to greatest extent after grinding aid mixes is that institute of each enterprise must consideration.
Summary of the invention
The present invention is the advantage in conjunction with solid and two kinds of grinding aids of liquid, and through various components are screened, the component of will being correlated with carries out heated compounded reaction, improves the component activity, strengthens stimulation effect.Reach and improve grinding aid, reinforced effects, reduce the purpose of grinding aid volume.
The present invention carries out on the basis of test analysis present grinding aid composition and result of use, adopts organic and inorganics to carry out compound raising component activity.Four kinds of selected components are respectively: trolamine, Industrial Salt, unslaked lime, sintering gypsum are carrier with slag or stone flour.Proportioning between the material and complex reaction determine that through a large amount of test compare of analysis the final weight ratio is: trolamine: Industrial Salt: cream during sintering: unslaked lime: slag (stone flour)=(2-3): (20-30): (0-10): (0-5): (55-65)
Produce and realize technology mode: according to various feature of raw material, need not fragmentation in process of production, various materials are adding fashionable must the adding in proportion through metering.Industrial Salt and unslaked lime and trolamine carry out compound tense will control pH value, temperature and reaction times, and the finished product are granular, slightly moist, various materials distribution uniform in product.
By using, this product addition content average out to about 0.2% in the powder process, compare with blank, blended material improves 10%, every performance index of cement all blank improve a lot, the cement grinding process situation is stable, through the cement performance that adds grinding aid is detected, the result is stable, meets product standard, and quality fluctuation is less.
The following advantage of tool of the present invention:
1. adopt organic and inorganic combining in the prescription, raw material need not be broken, and production worker technology is simple relatively, production efficiency height and constant product quality.
2. incorporation is few, reduces the ton cement grinding aid and mixes cost.
3. by using, the grinding aid reinforced effects of this grinding aid will surpass the grinding aid that the patent No.: ZL98110360.X produces.
4. cement production enterprise uses the unit-hour output that not only improves cement grinding mill, and reduces the grog consumption, improves the incorporation of " three wastes " blended material, reaches the tax-free requirement of country.Reduce the product energy consumption index, meet national circular economy policy.
5. this powder grinding aid volume is broken through the volume restriction of conventional powder grinding aid 0.8%, and according to a large amount of production data statistics, this grinding aid add-on in cement pulverizing course is about 0.2%.
When using this product cement quality be mixed with the patent No. (ZL98110360.X) and do not mix grinding aid at cement grinding mill production effect comparison cartogram.
| Grinding aid | Volume | Blended material | Fineness | 3 big resistance to compressions | Resistance to compression in 28 days | The cement grinding mill platform produces |
| Blank | 0 | 21.32 | 2.5 | 19.6 | 41.9 | 118t/h |
| This grinding aid | 0.2 | 32.73 | 3.8 | 22.6 | 42.2 | 128t/h |
| ZL98110360.X | 0.3 | 31.70 | 3.5 | 21.0 | 39.1 | 125/h |
As can be seen from the above table, this grinding aid will surpass the patent No. to grinding aid, the reinforced effects of cement: the ZL98110360.X grinding aid.
Embodiment
This product is apparent to be granular product, and being different from general is the powder grinding aid of carrier with flyash, the feature close according to raw material particle size, and the raw material of selecting for use need not fragmentation, just can enter to mix in the mixer through metering to get final product.
Production stage is earlier the quantitative Industrial Salt of part to be added in the gauge water, the heated and stirred dissolving also is warming up to about 90 degree, add quantitative three ethanol of part and unslaked lime, stir and temperature is remained on 90 degree, be incubated, display to transfer to about 3 hours in another bucket and mix with quantitative trolamine.
Remaining Industrial Salt, sintering gypsum, slag (stone flour) are fed mixer after metering and stir.Compound liquid is measured by volume pump, evenly feeds in the mixer continuously, and each component stirs and is finished product after handling equipment enters finished bin.
Claims (2)
1, powder enhanced type grinding aids is characterized in that: containing effective enhancing grinding aid composition of trolamine, Industrial Salt, sintering gypsum, unslaked lime and mixture thereof, is carrier with slag or stone flour; Weight proportion is: trolamine: 2-3; Industrial Salt: 20-30; Sintering gypsum: 0-10; Unslaked lime: 0-5; Carrier: 55-65; Production craft step: raw material is through metering, the part Industrial Salt added in the entry dissolving back add partly that trolamine heats up, and unslaked lime added adjust pH value in the liquid and carry out complex reaction, and insulation is displayed, and excites material activity in the component; Complex reaction liquid is added mixing behind the part trolamine again, through the volume pump metering continuously evenly in the feeding mixer; Again remaining Industrial Salt, sintering gypsum and carrier being fed mixer after metering continuously equably stirs; Described each component stirs and is finished product after handling equipment enters finished bin.
2, according to the described powder enhanced type grinding aids of claim 1, it is characterized in that: raw material need not fragmentation.
