Crushing: The extracted limestone is then crushed into smaller pieces using a crusher or a hammer mill. This process reduces the size of the limestone to a more manageable size for further processing.

The processing of limestone is mainly crushing, grading and producing quicklime, slaked lime, precipitated calcium carbonate, ultra-fine (nano) calcium carbonate, carbon dioxide, etc. Limestone generally adopts dry crushing process. For metallurgical and construction use limestone, only the ore needs to be crushed and screened.

secondary crushing as well. The crushed stone is screened to provide the desired stone size and then conveyed to storage in conical stockpiles (Gutschick, 1994). 2.1.2 Calcination Limestone is converted into lime through heating in a kiln, a process known as calcination.

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.
