Granulated blast furnace slag liquid composite grinding aid
The invention relates to a granulated blast furnace slag liquid composite grinding aid and belongs to the technical field of granulated blast furnace slag grinding process admixtures. The granulated blast furnace slag liquid composite grinding aid is prepared from triethanolamine, mixed alcohol, propanetriol, molasses, potassium carbonate, sodium pyrophosphate, sodium sulfate and water; and the granulated blast furnace slag liquid composite grinding aid is formed by composition of the most common chemical raw materials and industrial wastes, and has the advantages of low toxicity, no volatilization, stable sources, sufficient sources and low cost. After the granulated blast furnace slag liquid composite grinding aid provided by the invention is added into a grinding machine, the distribution and appearance of slag powder particles can be improved, the adverse effects on quality of slag powder are avoided, the effects of saving power consumption and improving grinding efficiency can be realized, and the granulated blast furnace slag liquid composite grinding aid has the advantages of better increasing the yield and improving the quality of the slag powder. Under the situation of same grinding time, the specific surface area of the slag powder is effectively improved, the screening residues are reduced, and the activity indexes of the slag powder in the early stage (7d) and the late stage (28d) are significantly improved.
