grinding aid for cement poly amine

cement grinding aids

Todays cement producers are expected to deliver superior performance while lowering production costs and minimizing their environmental footprint. GCP grinding aids make it easy to achieve these goals, enabling you to:

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. HEA2 is effective in both open circuit and closed circuit cement mills.

Our grinding aids are designed to increase mill output without increasing costs, while saving energy and reducing CO2 emissions. Improved cement flowability reduces the effort for handling and transporting cement.

For decades TAVERO HEA2, TAVERO LGA and TAVERO MTDA grinding aids have been used throughout the world to optimize the production of cement by ball mills. The introduction of TAVERO VM grinding aids round out the product line with solutions designed specifically for vertical roller mills (VRM).

GCP pioneered the development of chemical compounds for use in cement grinding over 80 years ago. Today, we continue that tradition of excellence by innovating chemical additives for the cement industry of the future. This commitment to innovation is matched by a commitment to service. We gladly offer tailor-made solutions for individual plants and cements, provide training for cement plant personnel and audit grinding systems to ensure our customers extract the maximum value from GCP grinding aids.

effects of grinding aids on model parameters of a cement ball mill and an air classifier - sciencedirect

Industrial scale tests were carried out with different types of grinding aids.Effects of grinding aids on grinding and classification operations were evaluated.Effects of the type and dosage of grinding aids on model parameters were examined.Grinding aids had influence on breakage probability, bypass and fish hook.Amine-glycol-polyol mixture was found to be the most effective.

This research focuses on investigating the effects of the three different grinding aids, consisting of a mixture of amine, glycol and polyol in different ratios, on the model parameters of a two-compartment cement ball mill and an air classifier. Within the content of this work, sampling campaigns were organized around a cement grinding circuit and each of the three grinding aids at varying dosage rates were tested. Then the ball mill and the air classifier were modelled by using perfect mixing approach and Whitens equation respectively. The relations between the types and dosage rates of grinding aids and model parameters were examined. The fact that such an examination has not been made previously by using industrial data, which makes this research unique. It was deduced that depending on the chemical composition of grinding aids, their effects on model parameters were varied and ultimately all of them improved the performance of the grinding and the classification operations.

effect of clinker grinding aids on flow of cement-based materials - sciencedirect

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 (0) and viscosity (). Grinding tests were performed at fixed specific energy consumption (Ec) or Blaine cement fineness. For fixed Ec, tests have showed that the increase in cement fineness resulting from the addition of higher GA concentration leads to reduced flow and increased 0 and values. Conversely, cement ground for fixed Blaine fineness exhibited an improvement in flowability together with reduction in 0 and values. This was related to a dispersion effect of cement agglomerates in the presence of GA molecules. Special emphasis is placed throughout this paper regarding the effect of GAs on ASTM C465 requirements.
