    Cement Clinker Grinding Aids. The use of a good Cement clinker grinding aid can be vital in today s 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. Sep 01 2014 · Grinding aids (GAs) are increasingly used during cement production to reduce energy consumption and/or optimize clinker factor. This paper seeks to assess the effect of such additions on variations in flow of cement pastes including static yield stress (τ 0) and viscosity (η).Grinding tests were performed at fixed specific energy consumption (Ec) or Blaine cement fineness.

    CementCementExtraction and processing Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones slates and some shales with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators. 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
