What are the 7 Zones in Rotary Kiln in Cement Production?
Function: This is the hottest zone in the rotary kiln, where the temperatures can reach up to 1450°C to 1500°C. In this zone, the raw materials undergo sintering, forming the cement clinker. Importance: The clinkering zone is where the final product is formed.
Cement Kiln Refractory for Charging, Calcining Burning
The calcining zone brick lining can exhibit alkali spalling; Seneca 60 P addresses that condition with superior resistance. On the other hand, the calcining zone refractories require higher alumina content for greater thermal resistance; Rescal 70D and Alumex P-8 are often best for this service.

The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). 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.
