Description

technical field

[0001] The invention relates to the field of cement production, in particular to a high-efficiency cement grinding aid. Background technique

[0002] At present, the country's requirements for low-carbon environmental protection are getting higher and higher, the price of cement is sluggish, the price of raw materials and energy is soaring, and the competition in the industry is fierce, which makes the benefits of cement enterprises stretched. In order to save energy and reduce emissions, develop a low-carbon economy, reduce cement production costs, and improve cement production efficiency, the most direct and effective method is to add a small amount of cement grinding aids in the cement grinding process. In the grinding process of cement clinker, adding a small amount of cement grinding aid can significantly improve the fluidity of cement, improve the grinding effect of the mill and the powder selection efficiency of the powder separator, and can improve th...
