• The surface energy of the clinker covered with grinding aid(E) is the algebraic summation of E1,E2 and E3. E= E3 + E2 + E3 11-05-2015 Indian Institute of Technology,Delhi 13 14. • If E = -ve that means the energy is released and the grinding aid spreads out on clinker's surface.
the industrial grinding of cement, even without the use of grinding aids. Therefore it can be assumed that the surfaces of the majority of commercial clinkers are predominantly or even completely hy - droxylated. This is also important because it as-sists the grinding, in other words water is a weak grinding aid. The chemical reaction of oxide ions
While the grinding aids had only a marginal effect on the grinding of quartz, they had a significantly beneficial effect on the grinding of limestone and cement clinker. Triethanolamine appeared to be the most effective of all the aids studied. In the grinding of cement clinker, gypsum also acted as a very effective grinding aid.

Description. SoundCem- GA is a liquid adding agent, for easy and fast grinding for producing fine quality of Portland and Hydraulic cement.; SoundCem –GA is manufactured in compliance with the specifications ASTM-C 465 and working as an excellent AID in processing .SOUNDCEM-GA is also a glycol/amine based product.
Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].
Advantageously, the grinding aid composition minimizes the agglomeration of cement particles as well as their adherence to the surface of grinding media (e.g., steel balls used in a grinding mill) thereby improving the energy and comminution efficiency of the grinding process.
