Grinding aids are common cement additives, and can consist of several different types of compounds such as alkanolamines, glycols or phenolic compounds. These are used to increase the throughput of cement clinker in the grinding mill. Generally, the concentration range of .
Oct 15, 2019· 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.
Cement grinding aid characteristics A grinding aid is a surfactant that can improve the grinding environment. The common grinding aid is to improve the grinding effect by improving the viscosity of the material in the mill, the dispersion of the particles and the flow state of the slurry.
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 .
