    Abstract. Balling is the single most critical factor controlling iron ore sintering process, as it increases mean size of raw sinter mix and permeability. Water is added as binder whose amount & properties greatly influence balling. Surface tension of water is a unique characteristic, which is a necessary evil as regards to balling
