Crushed limestone is used as roadstone, construction fill, iron smelting, ceramic wall tiles and flue gas desulphurisation.
Limestone Processing Flow
Limestone after its mining has to undergo several processing before it can be used in various processes. The basic processes in the production of limestone are (i) quarrying of raw limestone, (ii) preparing mined limestone for its use by crushing and sizing, (iii) calcining of raw limestone, (iv) processing the calcined limestone further by hydrating to produce hydrated lime if required for use, and (v) miscellaneous transfer, storage, and handling operations. All these processes may not be necessary to be present in every plant.
Quarry: Limestone is extracted from the rock either by blasting or mechanical excavation depending on the hardness of the rock.
Crushing: The extracted stone is transported for rough crushing.
Screening:After crushing the stone is sorted into different fractions by screening, after which it goes to be processed further.
Grinding:In the grinding process the limestone is ground to a fine powder.
