TAVERO® HEA2® is one of the most effective dispersants yet developed for use as a grinding aid/pack set inhibitor for portland cement and other hydraulic cements. HEA2 greatly improves the efficiency of the grinding process by reducing the surface energy forces which cause agglomeration of the newly fractured cement particles.

 — 1. Introduction. Cement is an energy-intensive industry in which the grinding circuits use more than 60 % of the total electrical energy consumed and account for most of the manufacturing cost [].The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In recent …
