Detection of alkanolamines in liquid cement grinding aids by

The raw materials of cement grinding aids samples with known amounts of grinding aids were chosen to match the range of the corresponding alkanolamines in the external standard solution. Thus, a 0.1g sample of liquid cement grinding aids was weighed into a 100 mL volumetric flask, and then dissolved and extracted with 100 mL of 9:1 (v/v) The history of grinding aids in dry fine grinding processes starts in the late 1930s with the application of the first commercial grinding aids in the cement industry [1]. Since that time, the importance of grinding aids in industrial dry fine grinding processes has strongly increased; so did the number of scientific papers dealing with this topic.Grinding aids for dry fine grinding processes ScienceDirect

Quantifying the effect of clinker grinding aids under laboratory

The effect of clinker grinding aids (GAs) on mill performance and cement properties is currently quantified in real-scale grinding plants. In fact, laboratory-grinding mills operated for given time interval do not consider the effect of circulating load, thereby leading to increased specific energy consumption (Ec) with excessively wide cement In particular, in the cement industry huge amounts of clinker, coal and other raw materials are need for grinding. It has already been proved that grinding aids sometimes referred to as grinding additives are one of the most effective measures to maximize energy saving and improve grinding efficiency in the cement grinding process Synthesis and super retarding performance in cement production
