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.
Mar 17, 2017 . The use of a good Cement clinker grinding aid can be vital in today's increasing material demands. Along with the obligation to process increasingly larger quantities of ores containing finely disseminated minerals, our limited energy resources and the rising costs of energy present a challenge to the.
A comprehensive research project was undertaken to evaluate the effect of grinding aids (GAs) on the percentage of clinker decrease and reduction of energy needed during the grinding process. Three GAs, based on amines, glycols and acids, were tested at various concentrations. The tested cement properties include.
This is because fine particles from ground materials agglomerate and adhere to the mill liners or grinding media as coating, reducing the impulsive force of the mill. In addition, the . Grinding Aids for Ball Mills. A ball mill . The aid also improved the dispersibility and fluidability of cement (powder) and weathering is delayed.
