The raw limestone for manufacturing calcium carbonate will be first crushed and grinded for size reduction, and then screened & washed to remove undersized material and then it is fed to the vertical shaft lime kiln for preheating, calcinations & cooling operation.
The operation 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 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.
The calcium carbonate manufacturing plant is equipped with two grinding mills, two classifiers, two superfine mills, crushing plant, a coating machine for treating with stearic acid and packing machines. With Zenith grinding technology, huge blocks of calcium carbonate are put through a complex grinding procedure to produce a powder uniform in particle size. The calcium carbonate produced by the plant is commonly used as a filling material in the production of products such as paper, ceramics and rubber.
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 calcium carbonate production plant design, and has been a world leading calcium carbonate manufacturing plant supplier and manufacturer.
