In Calcium carbonate production process, many different types of equipment involved including calcium carbonate quarrying plant, mining equipment, crushing machine, powder mill, separation machine etc. Zenith experts dedicated in optimizing precipitated calcium carbonate production plant design. It shows excellent performance in processing operations. It can also applied in beneficiation applications for many different types of minerals such limestone, sandstone, clay, kaolin, marble, talc, garnet etc.
Most of the calcium carbonate applied in industry is extracted by mining or quarrying. Pure calcium carbonate (e.g. for food or pharmaceutical use), can be produced from a pure quarried marble.
calcium carbonate grinding mill
The calcium carbonate generally needs to be pulverized in to fine powder for final applications. The extracted calcium carbonate or limestone minerals must be crushed and grinded for size reduction. Calcium carbonate powder milling is integral in preparation operation.
The calcium carbonate grinding mill is available with different types for producing various particle sizes, including ball mill, Raymond mill, high pressure mill, trapezium mill, ultrafine mill, coarse powder mill, vertical mill etc.
calcium carbonate processing 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.
