The rotary kiln is the central equipment for cement clinkering system in the new large dry processing cement production, which can be used with unistream or twinstream preheater, calcining combustor. 90%~ 95% of the raw material which has been precalcined has been fed into the slow rotating and inclining installed rotary kiln from the rear.
The main reasons of rotary kiln ring formation is the following. First, the ingredients of pouring raw material into the rotary kiln fluctuate wildly, and feeding volume is unstable, will inevitably lead to rotary kiln thermal system disorders.
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 in our case study that rings are typically formed in zones of maximal radiative heat transfer.
Adi3tek ® is a third generation fuel enhancer/chemical inhibitor specifically developed to block sulfurgenerated crust buildup in preheater/precalciners and to avoid ring formation in cement kilns. It consists of a proprietary blend of surfactant, dispersing and stabilizing agents as well as polymer inhibitors and fuel enhancer/catalysts.

A mass and energy balance for a cement rotary kiln was developed. Process parameters were taken from a fullscale cement plant in Norway which produces around 3400 tons of Mathematical Model for Alternative Fuel Combustion in a Rotary Cement Kiln Burner W. K.

cases, ring dams grow rapidly and cause the unscheduled shutdown of the kiln. In the last three years we registered on average at least one ring formation per month, of which seventy percent caused the unforeseen shutdown of the kiln for on average three days. Each of these kiln outages causes very important production and turnover losses.
