The next step in the process is to heat the blended mixture of raw ingredients (the raw mix) to convert it into a granular material called cement clinker. This requires maximum temperatures that are high enough to partially melt the raw mix. Because the raw ingredients are.

Rhino horn formation mechanism: Clinker dust carried back to the kiln with the secondary combustion air loses velocity around the burner and that causes clinker dust to settle and build up on the top of the burner. Figure-14: Rhino horn/ build-up on kiln burner c). Boulder: Generally, clinker ball/ boulder formation is related.

Counteracting ring formation in rotary kilns - Infoscience

Abstract. 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.
