Cement grinding aid
Cement grinding aid, CGA, Cement grinding agent, cement grinding additives
high efficiency grinding agent is a synthesis of the aminopolyether polyol, equipped with liquid products produced in a variety of alcamines small polar molecules. This product is chlorine free, low volume, high performance, non-toxic, non corrosive, non volatile, no adverse effects on cement.
1. this product is chlorine ion, no corrosion of reinforcement effect, is a kind of green products with high performance.
2. this product in the admixture of appropriate, can effectively increase the mill output, the general production in more than 15%. In the constant yield and strength of the mill case can reduce the 5-8% cement clinker.
3. the optimization of cement particle size distribution, improve the cement strength of all age, 3 days can be increased by 3~5MPa, 28 days can be increased by 3~5MPa.
4. improve the adhesion properties to reduce the raw material, paste, paste the ball to reduce or eliminate the cement particles and cement lining board over grinding phenomenon, improve liquidity and loading and unloading rate of cement, reduce power consumption.
5. no adverse effects on cement concrete and cement can be improved to some extent workability.
Usage and dosage:
1. the scope of use: This product is applicable to common portland cement standard variety, strength grade of cement.
2. this product volume: 0.05%~0.06%
1. small test
To determine the applicability of the raw material of this product and cement plant through the mill test, to determine the suitability test, into the large mill trial production.
2. big grinding test
According to the size of the liquid metering pump configuration mill output, and according to the mill production to output on the selection of feeding point after helping calibration grinding agent flow, total outflow with a stopwatch and cylinder was measured 1 min wife grinding agent, adjustment of grinding aid agent flow until the theoretical value.
2.2. washing grinding activation
The grinding agent according to slightly more than the mixing amount added to the material provisions into a mill for grinding 1~2 hours, as washing grinding activation process.
2.3. production adjustment
After activation, the mill production stage, will be the product fineness, specific surface control in the normal range, by listening to the sound of mill transformation gradually increased with a concomitant increase in mill production, in also to increase production at the same time, help the admixture of grinding agent. Under normal circumstances the mill tail hoist the current decline or product fineness, grinding sound is ringing, it can not change the direct production to help the admixture of grinding agent production rate, each time in principle does not exceed the original production to Taiwan 5%, minutes 2~4 times provided, more to the back of production should be smaller in amplitude overall, the amplitude of 10~20%.
1. grinding agent before use, should check and adjust the ability of auxiliary equipment.
2. the use of the process, should pay attention to the grinding media grading load change, regularly check the calibration accuracy of grinding aid agent dosage.
Package and storage:
200Kg barrels or custom-made according to the customer request, the storage period is generally six months.
This product should be stored indoors to avoid direct sunlight, avoid long time exposure to moisture by evaporation in the air.
