Problems solved by technology

[0002] At present, in cement production, when the liquid cement grinding aid is used to make cement, the grinding efficiency of the mill is low, and the strength of the cement is low.
Some currently used grinding aids contain chloride ions, sulfate ions, ammonium ions, and phosphate ions. Due to the existence of these ions, they affect the characteristics of cement, corrode the metal in the building, and affect the building. The durability of the mill using this grinding aid is low in grinding efficiency and low in cement strength

Abstract

The invention relates to an enhanced liquid cement grinding aid capable of improving the grinding efficiency of a cement grinding mill and enhancing the strength of cement. The liquid cement grinding aid comprises the components with the weight percentages as follows: 10 to 20 percent of triethanolmine, 5 to 10 percent of triisopropanolamine, 3 to 5 percent of diethylene glycol, 2 to 5 percent of sodium formate, 2 to 5 percent of sodium acetate, 1 to 3 percent of sodium lignosulfonate, 10 to 20 percent of desugarized molasses, 5 to 10 percent of glycerin, and water.

Description

technical field [0001] The invention relates to a grinding aid, in particular to an enhanced liquid cement grinding aid. Background technique [0002] At present, in cement production, when the liquid cement grinding aid is used to manufacture cement, the grinding efficiency of the mill is low, and the strength of the cement is low. Some currently used grinding aids contain chloride ions, sulfate ions, ammonium ions, and phosphate ions. Due to the existence of these ions, they affect the characteristics of cement, corrode the metal in the building, and affect the building. The durability of the mill using this grinding aid is low in grinding efficiency and low in cement strength. Contents of the invention [0003] The object of the present invention is to provide an enhanced liquid cement grinding aid capable of improving the grinding efficiency of a cement mill and enhancing the strength of cement. [0004] In order to achieve the above object, the technical solution ad...
