Rotary kiln zones in detail

Preheating Zone/Kiln Inlet Zone. 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

    Rotary lime kilns typically have four refractory zones with varying types of refractory. Long process kilns require abrasion resistant, high strength alumina brick for the charging zone. The charging zone is where the abrasion of the stone can be particularly severe. Short preheater kilns normally do not have a charging zone that sees high
