The invention provides a
slag vertical mill
grinding assisting activating agent and its compounding method. The
slag vertical mill
grinding assisting activating agent is composed of, by weight percent: 10-12% of industrial salt, 3-6% of
urea, 8-12% of
triethanolamine, 10-15% of
glycerol, 8-12% of an aluminum
sulfate solution, 3-6% of beet molasses, 5-8% of polycarboxylic acid, and the balance a
solvent. The method consists of: adding the industrial salt, the
urea, the
triethanolamine, the
glycerol, the aluminum
sulfate solution, the beet molasses, and the polycarboxylic acid into the
solvent in order, fully dissolving each
raw material when it is added, and conducting uniform stirring, then adding another
raw material till all the raw materials are added into the
solvent for dissolving, and mixing the mixture uniformly, thus obtaining the
slag vertical mill
grinding assisting activating agent, which can play a grinding assisting role and an activating role. By employing a compatible mode of chemical excitation and slag
powder particle size distribution improvement, the slag vertical mill grinding assisting activating agent provided in the invention has an
advantage complementary effect, not only adapts to
low activity acidic slag, but also adapts to neutral and alkaline slag, and is applicable to both vertical mills and ball mills.
