AI Technical Summary

Technical Problem

The high energy consumption of grinding in mineral powder production affects product quality and performance. Enterprises face the dual pressure of cost control and energy conservation and emission reduction, and existing grinding aids are difficult to significantly improve grinding efficiency and mineral powder performance.

Method used

The mineral powder grinding aid is made of a specific ratio of amine compounds, polyols, surfactants, retarders, nano-silica and high molecular polymers. By accurately adjusting the pH value and slowly releasing the retarder, it optimizes the mineral powder particle distribution and grinding process, prevents agglomeration, and improves the grinding efficiency and mineral powder activity.

Benefits of technology

Significantly improve grinding efficiency by 30%-40%, reduce energy consumption by 20%-30%, enhance the early and late strength of mineral powder, optimize particle distribution, comply with green environmental protection concepts, and improve the quality stability and performance of mineral powder.

Abstract

The invention belongs to the technical field of mineral powder grinding aids, and particularly relates to a mineral powder grinding aid and a preparation method and application thereof.The mineral powder grinding aid is prepared from, by weight, 15%-35% of alcohol amine compounds, 8%-20% of polyhydric alcohols, 4%-12% of surfactants, 2%-8% of retarders, 15%-40% of water, 1%-5% of nano-silicon dioxide and 3%-10% of high-molecular polymers; the invention further discloses a preparation method of the mineral powder grinding aid. The preparation method comprises the following preparation steps: S1, raw material pretreatment; s2, mixing; s3, adding and dispersing a surfactant; s4, preparing and adding a retarder capsule; s5, supplementing water and adjusting the pH value; and S6, carrying out post-treatment. According to the mineral powder grinding aid disclosed by the invention, the ingredients such as the alcohol amine compound, the polyhydric alcohol and the surfactant are accurately proportioned, all the ingredients synergistically reduce the surface energy of mineral powder particles, prevent particle aggregation and remarkably improve the grinding efficiency, the polyhydric alcohol is reasonably matched, the dispersion effect of the grinding aid in the mineral powder is improved, and the distribution of the mineral powder particles is optimized.
