The invention provides a liquid cement grinding aid for vertical grinding. The liquid cement grinding aid for the vertical grinding is prepared from 20%-30% of alcohol-amine salt of phthalic acid, 10%-15% of styrene-maleic anhydride copolymers, 10%-15% of tripolyglycerol, 10%-15% of glucose, 10%-15% of cane molasses, 1% of sodium hydroxide and the balance water. The liquid cement grinding aid for the vertical grinding has the advantages that due to the fact that the working condition of a cement vertical grinding machine is the same, and the various cement raw materials are the same, after the cement grinding aid is added, the particle size gradation of the cement is improved, the degree of sphericity of the cement product particles is improved, standard consistency water consumption of cement products is reduced, the adaptability between the cement products and concrete additives is improved, and the cement strength is slightly improved.
