Problems solved by technology

[0002] At present, in the market, in order to increase the output of cement in the ball milling process of cement, a large number of cement grinding aids are used, but the temperature of the cement grinding aids is too high, and the ball mill cannot work normally when the temperature in the mill is high and normal. Grinding aids cannot solve
During the use of the existing cement grinding aids in the market, the dust is huge, which seriously affects the normal production and has a great impact on environmental pollution.

Embodiment Construction

[0018] After the pulp waste liquid is filtered under normal temperature conditions, the active ingredients are added to propylene glycol, ethylene glycol, and triethanolamine, homogenized for three hours, then diethylene glycol and soda ash are added to homogenize again for eight hours, and then filtered again. Then heat it to about 100 degrees with steam, add urea for stirring, and then park it for seventy-two hours, which is the finished product.

Abstract

The invention is a cement grinding aid, which is made by adding propylene glycol, monoethylene glycol, trolamine, diethylene glycol, urea, soda to the filtered sulphite liquor. The cement grinding aid not only can help improve output of cement, but also effectively limit temperature of a ball grinder in the normal range during cement production; the cement grinding aid further helps maintain normal operation of the ball grinder, and prevent a huge amount of dust and environmental pollution.

Description

Technical field: [0001] The invention relates to a cement grinding aid product capable of controlling the temperature in a ball mill within a normal temperature range during cement production. Background technique: [0002] At present, in the market, in order to increase the output of cement in the ball milling process of cement, a large number of cement grinding aids are used, but the temperature of the cement grinding aids is too high, and the ball mill cannot work normally when the temperature in the mill is high and normal. Grinding aids can't solve it. During the use of the existing cement grinding aids in the market, the dust is huge, which seriously affects the normal production and has a great impact on environmental pollution. Currently, there is no product in the market that can solve the above problems, and this technical field is a blank. In order to overcome the above technical deficiencies of common cement grinding aids, the purpose of the present invention is...
