The invention relates to an efficient cement grinding aid. The efficient cement grinding aid is characterized by being prepared from the following ingredients in parts by weight: 10-20 parts of triethanolamine, 6-10 parts of ethylparaben, 1-2 parts of aluminum sulfate, 3-6 parts of triisopropanolamine, 1-4 parts of initiator, 5-10 parts of propylene glycol, 2-6 parts of sodium pyrophosphate, 1-2 parts of xanthan gum, 1-4 parts of sodium acetate, 1-3 parts of calcium formate, 5-10 parts of waste candy pomace, 1-2 parts of polytetrafluoroethylene and 2-6 parts of pulverized coal ash. The efficient cement grinding aid has the effects that the milling efficiency of a mill for cement can be remarkably increased by 8-15%, the early strength of the cement is properly improved by 2-3MPa, and the later strength of the cement is enhanced by 2-4MPa; all the ingredients are mutually synergistic, the adaptability of the grinding aid is improved so as to be applicable to different grades of cement, the range of use is enlarged, the grinding aiding effect is greatly improved, the production per machine hour is increased, the energy consumption is lowered, and the mixing amount is small and is 0.02-0.06% per ton of cement.
