Limestone Cycle

PCC manufacturing

• The Precipitated Calcium Carbonate Plant offered by us is made by following steps:

• Calcination / Burning of limestone in a vertical shaft lime kiln to give quick lime and carbon dioxide gas.

• Hydration of quick lime to give hydrated lime. • Washing and cooling of carbon dioxide gas. • Reaction of hydrated lime with CO2 gas to give

desired grade of precipitated calcium carbonate slurry.
