Prehydration of Clinker minerals can occur due to the following: As a result of poor drying in the mill, the cement produced would still contain a high moisture content. When there is insufficient gypsum dehydration in the mill, and the cement temperature entering the storage silo is too high. When cement is exposed to humidity.
CEMENT ROTARY KILN Questions & Answers Question-1: What is the maximum continuous shell temperature a kiln stands without permanent damage to the shell? Answer-1: 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.
