In order to comply with the most advanced standard, during the last years the use of grinding aids has been spreading in several countries. The grinding process of cement absorbs 60-70 of the total energy employed. Finish grinding accounts for about 38 of specific electric power consumption.
Free quote Send messageCement industry has a huge implementation rate for grinding aids because grinding mills grind the hard clinker into fine powder and the additives are used to enhance the grinding efficacy of the grinding mills. Due to industrys adoption, the electricity consumption has reduced tremendously.

Global Cement Grinding Aids Market Definition and Introduction.
The prime factor behind the usage of cement grinding aids is the elimination of the coating effect of clinker on grinding mill walls and to increase the production rate of cement keeping the surface area constant. Also, cement grinding aids are utilized to allow transportation in delivery trucks and storage in silos without lump formation.nbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbsp.
Global cement grinding aids market is segmented on the basis of product type, cement type, and region as given below.
On the basis of product type, global cement grinding aids market can be segmented as.
On the basis of type of cement, the global cement grinding aids market can be segmented as.
Geographically, the global cement grinding aids market can be segmented into seven key regions such as Latin America, Europe, Middle East amp Africa, South East Asia Pacific, Japan, China, and North America. The Middle East and South East Asia Pacific regions are anticipated to remain key regions in the cement grinding aids market throughout the forecast period. The emerging economies like India and China are achieving new highlights in the global cement grinding aids market.
Cement grinding aids for cement production and grinding aid. The beneficial effects of scientific and rational use of cement grinding aids on cement production 1 Improve grinding efficiency, increase bench production, and reduce power consumption. This is the most direct effect of using cement grinding aids.
Changes in performance such as liquidity. 5 Reduce CO2 emissions. CO2 emissions from cement production are mainly derived from calcination of limestone, coal for calcination, and coal-consuming electricity. Therefore, the grinding aid increases the amount of mixed materials and reduces the power consumption, which can greatly reduce the CO2 emissions from cement production.
4 Reduce costs and increase profits. Grinding aids reduce natural costs by increasing grinding efficiency and reducing clinker usage.
The use of a good Cement clinker grinding aid can be vital in today8217s increasing material demands. Along with the obligation to process increasingly larger quantities of ores containing finely disseminated minerals, our limited energy resources and the rising costs of energy present a challenge to the process engineer. One research route that has been explored for about half a century is the development of additives to the grinding mill feed that substantially improve the efficiency of grinding. Such additives are termed grinding aids.
With the wide application of grinding aids in the cement industry, the two types of grinding aids phosphate-based grinding aids and alcohol-amine grinding aids have further studied the two types of grinding aids and the physical properties of cement. The effect of grinding aids on the adaptability of cement and naphthalene based superplasticizer.
Considerably more effort has been expended in developing grinding aids for dry grinding systems than for wet grinding systems. Most of this work is oriented toward the cement industry, where huge amounts of cement clinker are dry ground in ball mills. Cement clinker is particularly difficult to grind, and the fine grinding of this material is one of the chief problems of the cement industry.
A variety of additives have been shown to have grinding aid characteristics for grinding cement clinker. Typical among these are amines, organosilicones, glycols, resins, cod oil, kojic acid, carbon blacks, wool grease, calcium sulfate, urea, asphaltenes, etc.
The results presented thus far indicate the applied nature of the research on grinding aids for dry systems. In other words, these results indicate the potential of a certain additive as a grindingaid for a specific material. However, even though additives have found successful commercial uses, as in the cement industry, the rational development and application of grinding aids requires a clear understanding of their mode of action.
It has been suggested that molecules of the grinding aid might penetrate deep into the tips of preexisting cracks and exert pressure on the crack tips, aiding the fracture process Lichtman et al.,1958. It is also very doubtful that this mechanism plays a role in impact fracture. Furthermore, as pointed out by Somasundaran and Lin 1972, the mechanism does not explain the effect of long-chain organic surfactants, which would have limited diffusion owing to their large size.
