• To either increase the surface area of cement at the given production rate or it can increase the production rate of cement keeping the surface area constant. 11-05-2015 Indian Institute of Technology,Delhi 6 Why Grinding Aids should be used?(contd.)
A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process. Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity.

Ball-milling cement raw materials requires only a few percent (<5%) of grinding aids [].To achieve finely ground PTFE, a mass ratio of the grinding aid (NH 4 Cl or CO(NH 2) 2)/PTFE of 4 was required.Therefore, the ammonium salts (NH 4 Cl and CO(NH 2) 2) not only played the role of a grinding aid, but also acted as the grinding medium (submicron-sized …
Cement grinding aids are classified into three key types based on the feedstock, such as amine-based, alcohol-based and ether-based grinding aids. 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 ...
Cement grinding aid and performance enhancers are additives that are used to perk up the cement production efficiency and simultaneously reduce the energy consumption. Cement grinding aids are mainly used for recuperating cement clinker grinding effectiveness, power, flowing ability, and potency expansion of binders.

A grinding aid composition suitable for grinding clinker into hydraulic cement powder, an improved grinding process and an improved cement product are disclosed. The grinding aid composition is composed of a mixture of at least one alkylene ether glycol and particulate carbon.
The cement grinding aids help in enhancing the efficiency of cement molturation process, which is the highest energy consuming process used for …
Effect of Grinding Aids on Wet Grinding. 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. Figure 4-26 shows a typical comparison ...
Additive compositions for use as grinding aids and pack set inhibitors in the manufacture of hydraulic cement composed of a water-soluble polyol, particularly a glycol, and a water-soluble salt of an aliphatic acid having no more than three carbons, said additive compositions being used either alone or in combination with water-soluble salts of a sulfonated lignin, a water-soluble …
Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.

Another addition to the product may be urea, which aids grinding efficiency. The urea when used in amounts up to about 5 percent of the sulfonated lignin material also increases the compressive strengths of cement. However, urea may be used in larger amounts with other additives without any deleterious effects on strength and set time.
