How Lime is Made
The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is "calcined" into lime. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime.
