Abstract

The invention discloses a composite steel slag grinding aid, and belongs to the technical field of industrial waste residue recovery. The composite steel slag grinding aid comprises a polyallylamine mixture, grinding-aid granules, an egg yolk hydrolysate, a camellia seed meal hydrolysate, tackifier, thixotropic agent and inorganic salt, wherein the polyallylamine mixture is obtained by introducingcarbon dioxide into a mixture of polyallylamine and water; the grinding-aid granules are prepared by mixing fly ash and sepiolite; the egg yolk hydrolysate and the camellia seed meal hydrolysate arerespectively obtained through enzymolysis of egg yolks and camellia seed meals, and then concentration; the tackifier is prepared from coal tar and carrageenan; and the inorganic salt is prepared frompotassium permanganate and ammonium nitrate. The composite steel slag grinding aid will not affect an activity, and has a good grinding-aid effect.

Description

technical field [0001] The invention discloses a composite steel slag grinding aid, which belongs to the technical field of industrial waste slag recovery. Background technique [0002] Grinding process is one of the most common particle mechanical optimization methods, widely used in the optimization process of cement clinker, slag, steel slag, fly ash and other silicate materials. Its main function is to optimize the particles to be ground to a suitable particle size, form a specific particle size distribution, and expand the specific surface area to achieve the purpose of increasing the effective reaction area of ​​the material and enhancing its pozzolanic activity. From the 1950s to the 1970s, large-scale grinding machinery began to be used and gradually matured. At present, due to the consideration of energy saving and environmental protection, various methods to improve grinding efficiency have been widely studied, and the development of grinding aids is one of the ho...
