Abstract

The invention discloses a self-made grinding aid. The raw material components are as follows: 10-15% of ethylene glycol, 20-35% of triethanolamine, 20-30% of glycerol residues, 1-5% of sodium acetate,1-2% of industrial salt, 1-3% of lignin and the balance water (totaling 100%). The preparation method comprises the following steps: step 1, during preparation, controlling the temperature of water to be 40-45 DEG C, adding the glycerol residues and the triethanolamine, and then uniformly mixing the glycerol residues and the triethanolamine; and step 2, adding glycerol residues and triethanolamine into water, and uniformly mixing, and sequentially adding ethylene glycol, sodium acetate, lignin and industrial salt. The self-made grinding aid can solve the problem of low yield of a mill in thecement production process, the clinker ratio is high, static electricity in the mill is eliminated, a cement grinding process is improved, the grinding efficiency is improved, and the production costof the cement grinding aid is reduced; the cement grinding table yield can be effectively increased by 5-7 tons / hour, the clinker ratio is reduced by 2.0%, the power consumption is reduced by 1.5-2 kilowatts / ton, and meanwhile, various chemical and physical inspection results of cement meet the national standard.

Description

technical field [0001] The invention relates to the field of grinding aids for cement production, in particular to a self-made grinding aid. Background technique [0002] Adding additional liquid that meets the national requirements in the cement production process can improve the grinding efficiency of cement, reduce the comprehensive power consumption of cement production, increase the production of cement units, and can effectively improve the strength of cement. At the same time, the ground cement meets the requirements of national standards. Analysis The performance and function of the raw materials required for self-made grinding aids, while ensuring that the addition of cement will not affect the performance of cement. [0003] The cost of existing grinding aids in the market is high, and the expected use effect cannot be achieved. Contents of the invention [0004] The object of the present invention is to provide a kind of self-made grinding aid, to solve the pro...
