Rotary Kiln Design: Cement Rotary Kiln Refractory

2020-6-11  The cement rotary kiln can be generally divided into preheating zone, lower transition zone, upper transition zone, sintering zone, and cooling zone. The length, temperature, and function of each zone are different, so the selection of refractory lining brick should meet the requirements of each area.

Kiln Zone ! Page 1 of 1 International Cement Review

2008-8-9  Re: Kiln Zone ! The burning zone of a cement kiln is the hottest part of the kiln, under the flame where the final combination into the clinker minerals takes place. Behind that burning zone is the upper transition zone where the temperatures is rising to that in the burning zone. In front of that burning zone where the clinker has been formed and

Cement Kilns: Design features of rotary kilns

2021-5-19  Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 were "straight", the rest having enlarged burning zones.
