Counteracting Ring Formation In Rotary Kilns Springerlink

Oct 24 2012 avoiding the formation of rings in rotary kilns is an issue of primary concern to the cement production industry we developed a numerical combustion model that revealed that in our case study rings are typically formed in zones of maximal radiative heat transfer this local overheating causes an overproduction of the liquid phase of the granular material which tends to stick to the ovens
