Natural calcium carbonate is formed from the sedimented remains of aquatic organisms which have built up over time to on the sea bed to form rock. The most common forms are chalk, limestone and marble. Precipitated Calcium Carbonate (PCC), the man-made from, is created by converting limestone into CaO and CO 2 and the subsequent reaction of both purified components in a chemical reactor.
The production process controls the carbonate very near to its original state, becoming into a fine ground product deposited in either dry or slurry form (water based suspension). Commonly, the processing involves washing, sorting of unwanted contaminants, grinding, size classification of particles, and maybe drying.
Production of Precipitated Calcium Carbonate 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 900°C. To ensure a high level of purity, the calcination process is carried out using natural gas.
The earth is full of treasures: ours is called calcium carbonate. This material, which is found in great quantities, is extracted by Umbria Filler in limestone deposits in Italy.. After grinding, particle size selection and chemical-physical processes, calcium carbonate takes on characteristics that allow it to be used as a filler in a variety of objects, many of which are unexpectedly common.
Adding Omya Calcium Carbonate fillers to the production process provides a significant increase in output rates. The natural properties of Calcium Carbonate improve drainage which leads to higher line speeds, reduced energy cost, and lower dependence on and recycled fibers.
