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. To a large extent, it solves the problems of powder

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 improving strength development [1]. In this paper we present a typical example of full

The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closed-circuit tube mill operating at

This is usually accomplished by mechanical action provided by high impact mill equipment. In the grinding stage, the cohesive forces inside the agglomerates have to be overcome. Energy is added to the system and therefore smaller particles (with a larger interface to the resin solution) are formed. This results in loosened inter-particle contact durability, that eases the destruction of

It was with the third concept, that is, controlling the slurry viscosity (rheology) that the greatest initial effects of chemistry on grinding rates were observed. It was on this concept that a very extensive chemical screening program was carried out leading to the filing and granting of a series of chemical use patents on grinding additives by Manfroy and Klimpel (1978-79).
