Product description

High efficiency grinding additive for cement making

High-efficient cement grinding aids, co-developed & produced by Tsinghua University with Zhengzhou Chengzhi Co., Ltd. Is a scientific allocation of several kinds of organic polymer surfactant. Non-toxic, non-corrosive, no adverse effects on cement. The product complies with the building materials industry JC/T667-2004 " cement grinding aids " standard, the adding amount should not exceed 0.5% of the cement mass; New national standard also increased the requirements on the limit of chloride ion, namely: The chloride ion content in cement should not exceed 0.06%. This product can be widely used in various types of cement production enterprises.

Function principle and Application scope
Grinding miller use mechanical force to micronize the solid material, during the grinding process, crashing and smashing occurs between materials and the ball forging media, makes the particles inside electrovalent bond cut off, to form a charge unit that generates static electric, adsorbing on the medium surface, appear to be pastes surrounding the grinding, thus cause energy waste, restricting the production.

CZZM series can effectively reduce materials' interfacial tension, reduce friction, clear away pastes surrounding grinding phenomenon, improve the powder flowability and avoid over-grinding phenomenon, thus achieve the effect of heightening the mill production. At the same time along with more reasonable distribution on the cement particle size and increasing trace active elements, the cement strength in each age have been strengthened, the cement fluidity has significantly increased.

High performance liquid cement grinding aids is applicable to ordinary portland cement, slag cement, fly ash cement, pozzolana cement, Portland cement and other cement composite production.

Performance
1. To improve the cement mill output: After adding the aids, under the premise of maintaining or slightly improving the cement's physical properties, the mill production capacity can be increased by 10 %.

2. Reduce the mill consumption: By improving the powder' surface charge performance inside the mill, it can eliminate the " pastes surround the grinder" phenomenon; Meanwhile the aids can improve the micro- cracks' extending of the powder particles, improve the grinding efficiency, thereby reduce the miller energy consumption, cement mill per ton of power consumption can be reduced by 10-20%.

3. To prevent "excessive grinding" and reduce the grinding temperature: Because of the grinding efficiency's raising, accelerate the cement mill's passing speed, to avoid "over-grinding" phenomenon, thus reducing the mill inside temperature. Grinding temperature's decrease can prevent dihydrate gypsum's dehydration, to improve the setting time and strength development and other cement performance.

4. To improve the cement's physical performance: To improve the cement strength (especially 10-20 % improve the early strength) or shorten setting time (especially the final setting time); Take advantage of added the grinding aids can help improve the cement's performance, can increase the mixing content amount, or add of part of the shaft kiln cement clinker in rotary kilns to reduce costs.

5. To reduce powder surface adsorption energy: Adding the aids can help reduce powder surface's static enrichment, to avoid the powder clumping and compaction to harden, eliminating cement silo bottom "bonding " phenomenon; Improve powder mobility, reduce transportation energy consumption;

6. Economic analysis by using cement grinding aids (Take 100T per year output cement companies for example )
