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.
A concrete plant or batching plant is very important equipment for the concrete construction. With the help of concrete batching plant, concrete used for the construction is produced by proper mixing of all the ingredients like sand, gravel, water and cement and then transported to concrete construction site ready to be poured for use.
The environmental and economic costs and benefits associated with burning sewage sludge in cement kilns will vary based on the energy content of the sludge (lower heating value) and the transportation distance between the wastewater treatment plant and proposed cement plant.
