Precipitated Calcium Carbonate Plant in Ghana2019-06-18

The precipitated calcium carbonate plant is processed 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.

Precipitated Calcium Carbonate Plant

The raw lime stone is first screened & washed to remove undesized material and then it is fed to the vertical shaft lime kiln for preheating, calcinations & cooling operation. Here process is controlled automatically and quick lime & CO2 gas are obtained. Then quick lime is hydrated with process water in batch reactor and screened to remove lime impurity. The line slurry is then further processed to reach at designed process conditions, required in reactor for carbonation. The CO2 gas from lime kiln is cooled and washed in a vertical washer and then it is charged to the batch reactor. The required conditions are maintained in reactor to obtain different grade of precipitated calcium carbonate. This slurry is further washed, filtered and dried to get fine powder of precipitated calcium carbonate.

Calcium Carbonate Production Line

Precipitated calcium carbonate is produced using the most economic process existing today. Limestone is converted into calcium oxide and carbon dioxide by means of calcination at temperatures in excess of 900буC. To ensure a high level of purity, the calcination process is carried out using natural gas. After the calcined lime has been slaked with water, the resulting milk of lime is purified and carbonated with the carbon dioxide obtained from the calcination process.

SBM provide complete series of calcium carbonate production line including crushing plant, powder grinding mill, drying plant, screening plant etc. We have installed many precipitated calcium carbonate plants in Ghana, India, Pakistan, Sri Lanka, Bangladesh, Indonesia, Philippines etc.

The often used crushing machine in calcium carbonate production includes jaw crusher, gyratory crusher, impact crusher, cone crusher and mobile crusher etc. These crushing machine can also be applied in processing of limestone, dolomite, calcite, marble stone, chalk, talc, mica etc.
