Abstract

A steel slag powder grinding aid for improving particle aggregation comprises, by weight, 45-48 parts of water, 4-6 parts of industrial salt, 2-3 parts of anhydrous sodium sulfate, 4-5 parts of sodiumnitrite, 2-4 parts of urea, 15-17 parts of compound alcohol amine, 17-20 parts of glycerol and 4-5 parts of sugar. The steel slag powder grinding aid can improve the grinding efficiency, improve theyield, reduce the power consumption of a mill, save energy and reduce the cost.

Description

technical field [0001] The invention relates to the technical field of mineral powder grinding, in particular to a steel slag powder grinding aid for improving particle aggregation and a preparation method thereof. Background technique [0002] Grinding aids are a kind of chemical admixtures. Adding a small amount or a small amount of this substance in the cement grinding process can improve the grinding efficiency and eliminate or reduce the phenomenon that hinders the normal grinding work. The aggregation of cement technology into large particles belongs to the macroscopic aspect, and the microscopic phenomenon is the re-healing of the cracks caused by the external force of the particles. During the operation of the pulverizer, the material and its temperature, the roughness of the grinding medium and the surface of the component will aggravate the formation of cladding and accumulation. When the grinding limit is reached, the material reaches a state of uniform quality, ...
