It can significantly increase the hourly output of cement, the strength of cement at various ages, and improve its fluidity. In the grinding process of cement clinker, adding a small amount of cement grinding aid can significantly improve the grinding efficiency or reduce energy consumption without damaging the performance of cement. Although there are many types of existing liquid mixing and stirring devices, such as dispersers, mixers, etc., they basically use stirring blades to make the liquid flow, so as to achieve the purpose of mixing.

Although the mixing efficiency is higher, due to the problems of the stirring device, the stirring efficiency is low, the time required is long, and the stirring effect is not good, and the quality of the produced products is poor. In the production process of cement grinding aids, it is affected by factors such as the purity of raw materials and the external temperature. It is inevitable that some impurities, precipitations, crystals and other insoluble substances will appear.
