What is claimed is: 1. Grinding aid consisting essentially of 47 to 98% by weight of a binder, 2 to 50% by weight of a filler and 0 to 3% by weight of a lubricant wherein the binder comprises one or more polysaccharides polysaccharide derivatives or both and the filler comprises one or more sugars, sugar alcohols or both. 2.
Possible ways to control such properties through the use of grinding aids for the purpose of improving grinding efficiency are delineated. Grinding efficiency can be defined as the amount of energy consumed per unit product of specific quality. Pulp fluidity is an important parameter in the process of transport of material and grinding media ...
The use of grinding aids in stirred mills has also been the subject of many investigations and consequently, it was stated that the use of GA in the stirred mills increased the grinding efficiency and reduced the specific energy consumption [15], [16]. Assaad et al. [17] examined the effects of amine and glycol based GAs on cement fineness.
Industrial tests were performed with an amine-based commercial grinding aid at three different dosage rates. • Influences of the dosage rates on grinding and classification performance were investigated. • The residence time of the cement particles inside the mill was decreased with the increasing dosage. •

Beside the grinding aids principal tUnction (output increases), the secondary benefit have also been appreciated (quality improvement of cement), and for th1S reason a distinction has been made within "pure grinding aids" and "grinding aids - performance enhancers" for the cement and other grinded binders. 2. CEMENT ADDITIVES CLASSIFICATION
The differential pressure between the inlet and outlet of the mill (ΔP mill) is an important process variable for the testing of grinding aids.ΔP mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of ΔP mill indicates more internal circulations and more fines. As a result of the higher ΔP mill, the mill vibration increases (8-10mm/s ...

1. Introduction. 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 [].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 have been traditionally used to improve the efficiency of the cement maturation process which is considered as one of the most energy consuming processes in cement production (60 - 70% of the total electricity consumed in the plant). They are usually added at the entrance of the mill together with the feed.
