Ring Formation - Page 1 of 9 - International Cement Review

Sep 11, 2009  Possible reasons for ring formation, Raw mix design, High coal ash. High liquid phase. Quality/ condition of refractory. High alkali feed. Burner pipe condition. Cooler condition. But to study all above reasons we have to run our kiln for 20 ~ 30 days continuously, we have technique to remove big clinker balls without stopping the kiln.

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

EVERYTHING YOU NEED TO KNOW ABOUT Coating and

Because the coating consists of particles that have changed from a liquid to a solid state, the amount that any kiln feed liquefies at clinkering temperature plays a very important role in coating formation. A kiln feed with a high liquid content at clinkering temperatures is more effective in coating formation than a feed low in liquid.
