In recent years, with the rapid development of the building materials industry and the adjustment of national industrial policies, cement grinding aids have been rapidly developed and widely used in the cement industry. According to incomplete statistics, more than 70% of cement enterprises have added grinding aids or similar products in the production process, which can significantly improve the grinding process, significantly increase grinding efficiency, reduce energy consumption, and reduce production costs for cement production enterprises. Improving the construction performance of cement and enhancing market competitiveness is undoubtedly an effective means.

At the same time, while ensuring the quality of cement, the increase in the amount of mixed materials promotes emission reduction and waste utilization, turning waste into treasure, reducing environmental pollution, and achieving significant social benefits. With the widespread application of grinding aids in cement enterprises, some application misconceptions have also emerged. On how to correctly use cement grinding aids, Oberstedt will explore the following based on actual situations.

Grinding aids, like other cement raw materials, can be adjusted according to the physical performance requirements of cement during use. However, changes in grinding conditions and raw materials during cement production can affect the actual effectiveness of grinding aids. The selection of the addition point is also important. Generally, liquid grinding aids are accurately and inexpensively added using liquid metering on material conveyors or grinding heads, or through online automatic feeding systems. However, it is also necessary to make a reasonable selection based on the temperature and moisture content of the grinding material. If the clinker temperature is above 80 ° C, it is recommended to add it to the grinding head. Therefore, in the process of using grinding aids in cement enterprises, the position and dosage of grinding aids should be adjusted appropriately according to the grinding conditions, and the maximum benefit of using grinding aids should be obtained through experiments.

Nowadays, many companies fix the amount of grinding aids added when signing contracts. Although this controls the cost of grinding aids, it limits the adjustment space for process supervisors and on-site operators, which affects the effective performance and most economical use of grinding aids. Therefore, in the practical application of grinding aids, enterprise managers should not be too limited to the amount of grinding aids added, but should allow production control personnel to conduct more experiments based on production conditions and adjust and determine accordingly.
