Problems solved by technology

At present, mineral powder grinding aids usually contain triethanolamine, compound alcohol amine, glycerin waste liquid, sodium lignosulfonate and water, but because triethanolamine is unfavorable to the hardening of mineral powder, the hardness of the ground mineral powder is not ideal, which affects the mineral powder. Powder use efficiency

Abstract

The invention provides a mineral powder grinding agent accelerating mineral powder hardening. The mineral powder grinding agent accelerating mineral powder hardening is composed of, by weight, 20-25 parts of water, 3-6 parts of industrial salt, 3-4 parts of sodium sulfate, 4-8 parts of sodium thiosulfate, 5-7 parts of sodium nitrite, 2-6 parts of urea, 1-5 parts of sodium lignosulfonate, 8-11 parts of triethanolamine, 35-40 parts of compound hydramine, 1-2 parts of glycerin and 1-2 parts of sugar. The mineral powder grinding agent is added to mineral powder to be grinded, so that the hardeningspeed of the mineral powder can be significantly improved, the production demand is met, the production cost is reduced, and the yield is improved.

Description

technical field [0001] The invention relates to the technical field of mineral powder grinding, in particular to a mineral powder grinding aid for accelerating the hardening of mineral powder and a preparation method thereof. Background technique [0002] According to the needs of mineral powder production, the interaction energy between materials is dispersed, and grinding aids are usually added to mineral powder. Mineral powder grinding aid, as a grinding aid additive, can reduce the cohesion and resistance between mineral powder particles, eliminate mechanical barriers, increase the specific surface area of ​​the material, reduce the sieve allowance, thereby realizing the grinding aid effect and improving the grinding efficiency of the mill. contribution. At present, mineral powder grinding aids usually contain triethanolamine, compound alcohol amine, glycerin waste liquid, sodium lignosulfonate and water, but because triethanolamine is unfavorable to the hardening of mi...
