Application Of Grinding Aids In Cement Production

Cement grinding aids has been introduced into the field of cement production for many years,it has played a role in improving grinding efficiency and reducing energy consumption.At the same time,more and more enterprises in southern Liaoning Province transformation to grinding station,the main products are granulated blast furnace slag powder and composite Portland cement,etc..This paper will focus on the effect of grinding aids on the properties of granulated blast furnace slag and compound Portland cement,and the concrete contents are as follows:First of all,this paper studies two alcohol amine help grinding agent of blast furnace slag,slag Portland cement and composite Portland cement help grinding effect.Through the incorporation of grinding aid agent of slag powder specific surface area test,the slag Portland cement are grinding test results,and on the hybrid materials with different composition of composite Portland cement help grinding effect test,to item by item analysis of the two kinds of alcohol amine grinding aids grinding effect.Second,the mixture of triethanolamine and three isopropanol amine,made of compound cement grinding agent,the composite Portland cement to help test the effect of grinding.In addition,triisopropanolamine as the main object of compound,compound grinding agent is developed.Through the test found that tea and TIPA the assistance of slag grinding effect is very good.At the same time,tea and TIPA of slag Portland cement of some indicators have enhancement effect and TIPA to better than tea;in addition,from the help of composite Portland cement grinding effect,the two grinding effect in a certain extent depends on Composite Portland cement admixture composition.And both the mixed results have shown that two kinds of alcohol amine help agent mixing mill is just a simple superposition,and is not able to by both the mixture,so that the grinding effect is more significant.At the same time,it is not difficult to find TIPA as a substitute of TEA in the compound test of three different alcohols,which can play a very good grinding effect and greatly reduce the production cost of cement grinding aids.
