The addition of grinding aids to the clinker in cement
The addition of grinding aids to the clinker in cement production is indeed important for several reasons Firstly, the fineness (Blaine specific surface) of the finished cement is one of the main factors that are affecting the development of early strength Besides, the addition of grinding aids provides an energy consumption which consumed during cement [] Clinker and gypsum, being mixed together in predetermined proportions, are fed to the grinding mills Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter grinding CLINKER GRINDING UNIT PROCESS Mechanical the clinker in the cement mill Their main purposes are to reduce the energy consumed in grinding the clinker In addition to increase the efficiency of the mill, some grinding aids can also provide important positive effects on the final cement paste like the reheology and the improved strength development1,2 Grinding aids that providesThe influence of Triethanol amine and ethylene glycol on Grinding aids are widely used to enhance mill output, improve fineness and reduce energy consumptionPerformance enhancers permit to boost clinker reactivity (PDF) Overview of cement grinding: fundamentals, Figure 1 shows the typical comparison between grinding of cement clinker with and without a grinding aid in a laboratory mill As discussed in the literature [1,2,4], there was significant effect of using grinding aid in cement grinding Grinding aids are active surface agents that counteract the agglomeration of very finePAPER OPEN ACCESS
