Cement raw material grinding aid as well as preparation method and application thereof

The invention relates to the technical field of cement production, and provides a cement raw material grinding aid as well as a preparation method and application thereof. The cement raw material grinding aid provided by the invention is prepared from the following components in percentage by mass: 10-25% of organic acid salt; 11%-24% of polyester; 9 to 16 percent of polyalcohol; 2%-5% of a rare earth stabilizer; and 45%-60% of deionized water. In the invention, the organic acid salt not only can reduce the healing trend of microcracks on the hard coarse particles, make the hard coarse particles easier to crush and refine and reduce the energy consumption of grinding, but also can reduce the lattice energy of the hard particles, activate the particle structure, improve the reaction activity during calcination and reduce the coal consumption during clinker firing; polyester and polyalcohol can disperse raw material particles, prevent the raw material particles from being agglomerated, improve the grinding effi
