In the cement industry production, in order to improve the grinding efficiency, reduce the power consumption of the mill, reduce the fineness of the cement, and improve the quality of the cement, a small amount of material-grinding aid must be added during the grinding process. The grinding aid is composed of one or more surface active substances and other chemical additives. It can reduce the surface energy of the grinding powder during the grinding process, overcome the attraction between the grinding powder, reduce the crushing resistance and prevent Paste the ball. Improve the fluidity of the mill, thereby reducing the power consumption of the mill and improving the grinding efficiency.
Make full use of industrial, agricultural and sideline waste, and chemically transform a large number of workers and agricultural waste. The waste is converted into an active material by acidification, alkalization, basement, olefination, sulfonation and the like. For example, the lignosulfonate grinding aid currently used is converted from a component in a paper plant sulphite waste liquid, and the onion, Cai, and tar in the coal tar can also be sulfonated and alkali. It is made into an anionic surfactant of alkyl and sulfonate; the molasses and sugar slag of the sugar factory are all light organic substances, and the peat and lignite are all rich in humic acid, which can be converted into active by chemical methods. The substance constitutes a grinding aid.
