A cement kiln incinerator is an option that can be used to incinerate most hazardous and nonhazardous wastes. The rotary kiln type is the typical furnace used in all cement factories. Rotary kilns used in the cement industry are much larger in diameter and longer in .
CEMENT ROTARY KILN Questions Answers Question1: What is the maximum continuous shell temperature a kiln stands without permanent damage to the shell? Answer1: The maximum recommended kiln shell temperature varies by plant, by country and by kiln manufacturer, despite the fact that most kiln shells are made of low alloy carbon steel.
