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 …

Cement is basically is made by heating limestone (calcium carbonate) with small quantities of other materials to 1450°C in a kiln. The resultant hard material which is recovered after heating limestone and chemicals is called 'Clinker'. Clinker looks like small lumps.

CEMENT GRINDING AIDS. Dr J D Bapat. The cement grinding aids are the additional materials (gas, liquid or solid), admixed in small amounts during the cement grinding process (cement manufacture), which can significantly improve the grinding efficiency, reduce energy consumption, without compromising the performance of the cement. Some commonly …

Cement grinding aid application accounted for over 70% of total downstream consumption of diethanol isopropanolamine (DEIPA) in global. On the other hand, DEIPA prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process and make it possible to streamline the cement-making process by increasing process ...

Advances in cement grinding technology are slow and these advances are limited to more developed countries. Approximately 95% of the feed to the cement grinding circuit are clinker and the rest of the feed are „„additives‟‟ which includes grinding aids. The quality of cement is measured by the surface area or the Blaine index.

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. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration ...

The LCCP was produced at a cement-grinding unit of J. K. Lakshmi in Jajjhar, India by inter-grinding the raw materials in a ball mill. The ratio of calcined clay to limestone was kept as 2:1, based on earlier studies (Antoni, 2013; Bishnoi et al., 2014; Emmanuel et al., 2016).
