Grinding additive for powder-grinding steel slag in vertical mill
The invention discloses a grinding additive for powder-grinding steel slag in a vertical mill. The grinding additive is prepared from the following raw materials in percentage by weight: 1-5 percent of polyacrylic acid, 5-10 percent of molasses, 1-5 percent of sodium hexametaphosphate, 2-6 percent of tetraethylammonium oxalic acid, 3-10 percent of triethanolamine, 5-20 percent of aluminum sulfate and 46-81 percent of carriers. All components of the grinding additive are cooperated with each other, so that the grinding efficiency of the steel slag in the vertical mill is improved, the active indexes are improved, and the adverse effect on cement and concrete performance is avoided. Compared with the prior art, the grinding additive for grinding steel slag in the vertical mill has the advantages that a material layer can be stabilized, the yield of the mill is increased, and the active indexes of the high steel slag powder 7d and 28d can also be increased.
