Cement grinding aid is a kind of chemical additives can improve cement grinding effect and performance, can significantly improve the cement production, every period cement strength, were to improve its liquidity.Cement grinding aid can greatly reduce the grinding ball phenomenon formed in the process of electrostatic adsorption package, and can reduce the grinding of ultrafine particles in the process of coalescence trend again.Cement grinding aid can significantly improve the liquidity of cement and improve the mill grinding effect and efficiency of classifier choose powder, so as to reduce the energy consumption of grinding.Using grinding agent in the production of cement with a low compaction trend of coalescence, which benefits the loading and unloading of cement, and can reduce the phenomenon of wall hanging cement silo.As a kind of chemical additives, grinding agent can improve the cement particle distribution and hydration, so as to improve the early strength cement and later strength.
