Enhanced cement composite grinding aid

Abstract

The invention patent relates to an enhanced cement composite grinding aid, pertaining to a cement additive. The enhanced cement composite grinding aid has the following main ingredients in percentagesby weight: 45 percent to 90 percent of diethanol isopropanolamine, 10 percent to 30 percent of molasses, 5 percent to 20 percent of lignosulphonate, 0 percent to 15 percent of inorganic dispersant and 0 percent to 30 percent of water. The main ingredient of the grinding aid, diethanol isopropanolamine, is a substitute for trolamine and triisopropanolamine in respect of property and the property thereof is superior to single trolamine or triisopropanolamine grinding aid. The application of the enhanced cement composite grinding aid to cement production can effectively increase output per machine hour of a grinder, improve cement strength in early period and later period, and reduce cement production cost.

Description

technical field

[0001] The patent of the present invention relates to an enhanced cement composite grinding aid, which belongs to cement additives. Background technique

[0002] my country is a big country in cement production and consumption. Cement production needs to consume a lot of resources and energy, and emit a certain amount of air pollutants to the natural environment. In the process of cement production, the environmental load of the two processes of "clinker calcination" and "cement grinding" is the most serious. Among them, grinding is an important process of cement production. For every ton of cement produced, various materials need to be ground About three tons, the power consumption of the grinding process accounts for about 60-70% of the total power consumption of cement production. If the cement industry wants to maintain sustainable development, it must take measures to reduce resource and energy consumption and reduce the emission of harmful substances t...
