Jan 31, 2015· Abstract. Effects of modified triethanolamine as cement grinding aids on particles characteristics and mechanical property of cement were studied, and its reaction mechanism was analyzed by IR, Zeta potential, SEM, XRD and TGDTA.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Grinding aids are organic substances that are strongly adsorbed on the surface of ground particles, so that preventing agglomeration and coating on ball and mill lining. Thanks to their dispersing effect, grinding aids also increase the efficiency of air separators because the finest particles are not carried along with the largest.
A comprehensive research project was undertaken to evaluate the effect of grinding aids (GAs) on the percentage of clinker decrease and reduction of energy needed during the grinding process.
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 reagglomeration, or readhering, during and after the grinding process. Grinding aids make it possible to streamline the cementmaking process by increasing process efficiency and material fluidity.
