The invention discloses a composite cement grinding aid, which consists of the following components in parts by weight: 5 to 35 parts of polyalcohol amine, 3 to 15 parts of polyalcohol, 5 to 15 parts of molasses, 4 to 8 parts of sodium metasilicate pentahydrate, 4 to 6 parts of sodium hexametaphosphate and 25 to 40 parts of water. The composite cement grinding aid has stable material sources, is environment-friendly and low in toxicity, and is easy to produce and manufacture; by determining respective components and content ranges, respective components can achieve a better synergistic effect, so the effectiveness of the grinding process can be optimized, and the distribution and morphology of individual cement particles can be improved; the composite cement grinding aid does not have adverse influence on cement quality, has the advantage of effectively increasing output and cement quality, and can also play the role of saving electricity, increasing grinding efficiency and cement strength, reducing free calcium oxide in cement and increasing the early strength and later strength of the cement.
