Limestone
Limestone is a basic type of ore which is abundant in the world. It is primarily used to produce Concrete, an essential material in factory construction.

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.
