2018-3-29 Grinding aids for high performance cements 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.
Description. Di ethanol isopropanol amine (DEIPA) is an alkanolamine used in the formulation of cement additives and concrete admixtures. This compound is used as a cement mill aid because it prevents the accumulation of cement particles during the process and after grinding, which leads to increased process time efficiency, uniformity of materials.
Diethanol-isopropanolamine (DEIPA) is a new type of alkanolamine used as grinding aids for Portland cement. In this study, the effect of DEIPA on properties of Portland limestone cement (PLC) were investigated by measuring strength of mortar, setting time, compatibility of cement and superplasticizers.
DEIPA or TEIPA may be added to the clinker during the finish grinding stage to help reduce the energy require-ments and provide a uniform free flowing cement powder with reduced tendency to form lumps during storage.It is also possible to add the subject additives as an admixture to powdered cement either prior to, in conjunction with,
Cement Additives are a Popular Choice Because They. Positively affect the production process and the quality of cement.
