Mineral powder grinding aid based on physicochemical double action

Abstract

The invention discloses a mineral powder grinding aid based on physicochemical double action. The specific steps comprise: 1, weighing corresponding sulfate, aluminate, calcium carbonate, polyacrylamide, diethanolisopropanolamine and water, carrying out heating mixing and diluting according to a certain ratio to obtain a composite liquid grinding aid material; 2, producing slag activation micro-powder from neutral or alkaline slag with a high mass coefficient by using an open-circuit ball mill grinding method; 3, adding the composite liquid grinding aid material prepared in the step 1 in the grinding process in the step 2; 4, sequentially treating through settling cooling, and collecting by using a cloth bag dust collector to obtain superfine slag powder; and 5, sampling the superfine slagpowder obtained in the step 4, analyzing by using an image analyzer, and checking whether the superfine slag powder reaches a proper specific surface area. According to the invention, with the grinding aid of the invention, the concentration force and the resistance among particles can be effectively reduced, the mechanical shielding can be slowed down, and the effects of specific area increasingand screen residue reducing are achieved.

Description

technical field [0001] The invention belongs to the technical field of mineral powder processing, and in particular relates to a mineral powder grinding aid based on physicochemical twin effects. Background technique [0002] The existing mineral powder grinding technology mostly uses ordinary ball mills, and consumes a lot of power. In order to reduce power consumption, coal ash is added to the slag for grinding aid. The maximum use activity of slag micropowder cannot be brought into play. Contents of the invention [0003] The purpose of the present invention is to provide a mineral powder grinding aid based on physical and chemical twin effects, to solve the problem that the existing mineral powder grinding technology proposed in the above-mentioned background technology mostly uses ordinary ball mills, and consumes a lot of power. Adding coal ash to grinding aid, the result is that the output is increased, but the mass activity is reduced, which leads to the reduction...

[0003] The purpose of the present invention is to provide a mineral powder grinding aid based on physical and chemical twin effects, to solve the problem that the existing mineral powder grinding technology proposed in the above-mentioned background technology mostly uses ordinary ball mills, and consumes a lot of power. Adding coal ash to the grinding aid, the result is that the output is increased, but the mass activity is reduced, which leads to the reduction of the use intensity of the slag powder, and the problem that the maximum use activity of the slag powder cannot be exerted.
