Grinding Aids for Ball Mills Industrial Efficiency, Grinding Aids for Ball Mills 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 agglomerated particles are mixed into the coarse powder in the separator and recirculated through the mill...
Grinding aids are added at low dosages, typically in a range of 0.02% - 0.05%, either onto the mill feed or directly into the mill itself. They reduce or even neutralise the surface energy by shielding the polarity to different degrees.
Cement grinding aids have been used for improving cement clinker grinding efficiency, power flowability, and strength development of binders. Moreover, cement grinding aids have positive effects on the mechanical properties of cement, such as setting time, compressive strength, surface area, and mortar workability.
Some commonly used cement grinding aids are triethanolamine (TEA), mono- and diethylene glycols (DEG), oleic acid, sodium oleate, sulphite waste liquor and dodecylbenzene sulphonic acid sodium lignosulphonate (from paper industry). The cement grinding is an energy intensive process.
