Precipitated light calcium carbonate production equipment ...

Precipitated light calcium carbonate production process: firstly, limestone and other raw materials are burnt to produce lime (the main component is calcium oxide) and carbon dioxide, and then water is added to the lime to produce lime milk (the main component is calcium hydroxide), and then carbon dioxide is introduced into the carbonized lime milk.

Calcium Carbonate Filler

Precipitated calcium carbonate (PCC) can be produced by "calcining" limestone at very high temperature to drive off CO2, "slaking" the resulting lime by addition of water, and then treating the resulting "milk of lime" suspension with CO2 gas under highly controlled conditions of temperature, pH, and ionic composition. The process results in ...
