What is a grinding aid?

　　What is an abrasive aid! It is an additive to improve the efficiency of grinding. It can generally be glass beads, quartz sand, etc. To improve the grinding efficiency and reduce the power consumption of grinding operation is an effective means to improve the economic efficiency of cement enterprises, in order to achieve this purpose, domestic cement enterprises generally take two measures: one is to improve the structure of the grinding machinery, improve the grinding process and the way to make more institutions can act on the material through the grinding media; another method is to add a trace or a small amount of additives in the grinding process, that is, grinding aids to influence the mechanical and chemical processes in the grinding The other method is to add trace or small amount of additives to the grinding process, i.e. grinding aids to influence the mechanics and chemistry of the operation, so as to achieve the purpose of improving grinding efficiency. The latter has the advantages of low investment, quick results, simple operation, and can improve the physical properties of cement, etc., and has been gaining more and more attention.

　　It is generally a surface active material, which has the effect of reducing the specific surface energy and "wedging" the particle cracks.

　　In the process of fine grinding, the particles are gradually refined, the specific surface area increases, the surface is charged due to broken bonds, particles adsorb each other and appear agglomerated, so that the crushing efficiency decreases. Adding a small amount of grinding aid can prevent particle agglomeration and improve material fluidity, thus improving the efficiency of ball milling and shortening the grinding time.

　　Such as alumina dry grinding with the right amount of oleic acid, wet grinding with a small amount of aluminum chloride. When grinding ordinary porcelain, add a certain amount of sulfite pulp waste, etc.

　　There are many kinds of grinding aids, which vary according to the grinding materials. Generally, polymer compounds: polymer polyol, polymeric alcohol amine, triethanolamine, triisopropanolamine, ethylene glycol, diethylene glycol, etc. are the preferred materials.

　　For cement grinding aid, it can be defined as: one or more surface active substances with an admixture of not more than 0.5% that can improve the grinding performance of materials in cement processing and improve the grinding efficiency.

　　To improve the grinding efficiency and reduce the power consumption of grinding operation is an effective means to improve the economic efficiency of cement enterprises, in order to achieve this purpose, domestic cement enterprises generally take two measures: one is to improve the structure of the grinding machinery, improve the grinding process and the way to make more bodies can act on the material through the grinding media; another method is to add a trace or a small amount of additives in the grinding process, that is, grinding aids to influence the grinding The other method is to add trace or small amount of additives to the grinding process, i.e. grinding aids to influence the mechanics and chemistry of the operation, so as to achieve the purpose of improving grinding efficiency. The latter has the advantages of low investment, fast results, simple operation, and can improve the physical properties of cement, etc., and is being paid more and more attention to.
