Problems solved by technology

Therefore, adding a small amount of grinding aids in the grinding process can shorten the grinding time and reduce energy consumption under the same fineness conditions. Commonly used grinding aids include triethanolamine, polyols (such as ethylene glycol, propylene glycol) etc., but the grinding effect is still not ideal

Embodiment 1

[0008] A cement clinker grinding aid consists of 100 parts by weight of triethanolamine, 5 parts by weight of ethyl cellulose and 2 parts by weight of acetic acid.

Embodiment 2

[0010] A cement clinker grinding aid consists of 100 parts by weight of triethanolamine, 7 parts by weight of ethyl cellulose and 2 parts by weight of acetic acid.

Embodiment 3

[0012] A cement clinker grinding aid is composed of 100 parts by weight of triethanolamine, 8 parts by weight of ethyl cellulose and 1 part by weight of acetic acid.

[0013] Compared with using triethanolamine alone, under the condition of the same amount of grinding aid added and the same grinding fineness, the cement clinker grinding aid of the present invention can shorten the grinding time by 30-45%, thereby reducing energy consumption. consumption and improve efficiency.

Abstract

The invention discloses a cement clinker grinding aid composed of 100 parts by weight of triethanolamine, 5-8 parts by weight of ethyl cellulose and 1-2 parts by weight of acetic acid. Compared with traditional grinding aids, the cement clinker grinding aid can obviously shorten the powder grinding time, reduce the energy consumption and improve the efficiency.

Description

technical field [0001] The invention belongs to the field of cement admixtures, in particular to a cement clinker grinding aid. Background technique [0002] Cement production is a high-energy-consuming industry, among which raw material processing and clinker grinding account for about 17% of the total energy consumption, while most cement enterprises in my country use tube mills, whose grinding efficiency is extremely low, accounting for about 97% of energy consumption. converted into heat and dissipated. Therefore, adding a small amount of grinding aids in the grinding process can shorten the grinding time and reduce energy consumption under the same fineness conditions. Commonly used grinding aids include triethanolamine, polyols (such as ethylene glycol, propylene glycol) etc., but the grinding effect is still not ideal. Contents of the invention [0003] The object of the present invention is to provide a cement clinker grinding aid with better grinding aiding effec...
