Rotary kiln discharge

The first reaction zone of rotary kiln system is known as the preheating zone. Here the charge gets heated up to about 800℃ before entering the calcining zone. Bricks in this area are prone to chemical attack from gases containing alkali and sulphur. ... Discharge Area. This is the kiln tip area where clinker falls into the cooler at about
