It is mainly used for raw meal grinding and clinker burning in the new dry process cement production line.

Application effect ① increase the unit time of raw mill: the average output of raw mill per unit time is increased by 2% – 10%, and the output of kiln is increased by more than 2%; ② Improve the quality of clinker: the average strength of clinker will increase by about 1MPa in 28 days; ③ Reduce coal power consumption: the comprehensive power consumption per ton of clinker is reduced by more than 1.5kw · h, and the standard coal consumption is reduced by more than 2-6kg; ④ Improve mill working conditions: reduce mill vibration, etc.; ⑤ Improve the working conditions of cement kiln: fly sand, scaling, granulation, adaptation to high saturation ratio, etc.

The annual output of cement in China has exceeded 2 billion tons, and the consumption of concrete is also the highest in the world.

However, the carbon emissions, high energy consumption and uneven quality of sand and gravel aggregate for concrete caused by the preparation of cement have become important factors restricting the low-carbon and high-quality development of the building materials industry.

Cement raw meal grinding aid Cement raw meal energy saving grinding aid (QBS-C-RGA), as a new type of energy saving and consumption reduction product, can be added in the raw meal grinding process.

QBS-C-RGA is mainly composed of polyester, polyol, organic matter, etc.

Today, in addition to strictly controlling the quality of raw materials, adding industrial additives for building materials has gradually become an important technical path to optimize the process from the source.

Product characteristics improve the grindability and burnability of raw meal, increase the decomposition rate of limestone and reduce the decomposition temperature of limestone by 10-20 ℃.

By reducing the material surface energy, fine control of raw meal powder size, improve its homogeneity and dispersion, and then achieve the purpose of energy saving and efficiency.

Through the application of energy saving grinding aids for raw meal, the fine control of cement raw meal size is realized, and the balance between the burnability and grindability of raw meal and the suspension and dispersion separation efficiency of the preheating system is taken into account, so as to determine the optimal control scheme of raw meal fineness, thus achieving the purpose of energy saving and consumption reduction.

The Research Center for Solid Waste Utilization and Low-carbon Building Materials has been rooted in industrial additives for several years, focusing on the whole industrial chain of the building materials industry, developing a variety of new industrial additives such as metallurgical slag vertical mill synergist, cement water-soluble Cr6+liquid reducing agent, cement mineralizer, and providing customized technical services according to the needs of enterprises to help the building materials industry achieve carbon peak.

At the same time, achieve multiple effects such as increasing the output of raw meal grinding table, reducing the power consumption of raw meal grinding, increasing the output of clinker kiln, reducing the coal consumption of clinker, reducing the carbon-sulfur emissions and improving the quality of clinker.

The products refer to the standard T/CCAS021-2021 Cement Raw meal grinding aids.

⑥ Taking the annual output of 1 million tons of clinker as an example, the annual CO2 emission will be reduced by more than 60000 tons.
