Calcium carbonate (CaCO3), which occurs primarily in the form of the minerals calcite and aragonite, is one of the most prevalent compounds on Earth. Calcium carbonate is not only the main component of marble, limestone and dolomite, it is also found in bones and teeth as well as the exoskeleton of crustaceans, coral, muscles, snails and protozoa. A further modification of CaCO3 is the mineral vaterite, which precipitates out of supersaturated solutions in the form of microscopic crystals.

In addition to kaolin and talc, calcium carbonate is used in the paper industry as a filler and coating pigment in the production of paper. Since calcium carbonate is rhombohedral even when very finely ground, it is primarily used in papers with the highest degree of whiteness and good printability. Examples of these are coated printing papers or highly filled copy and office papers.

NETZSCH is expanding its product portfolio with an agitator bead mill for the dry grinding of mineral and ceramic raw materials. The Pamir impresses with very high product fineness and high throughput rates with low specific energy consumption.

The heavy calcium carbonate particles are irregular in shape and are polydisperse powders. Its particle size is large, and the average particle size is generally 5-10 m, and the distribution is wide. It is almost insoluble in water, soluble in water containing ammonium salts or ferric oxide, and insoluble in alcohol. In the case of dilute acetic acid, dilute hydrochloric acid, dilute nitric acid, it is inflated and dissolved. The heat is decomposed into calcium oxide (CaO) and carbon dioxide (CO2).

The light calcium carbonate particles are regularly shaped and can be regarded as a monodisperse powder, but can be of various shapes such as a spindle shape, a cuboid shape, a needle shape, a chain shape, a spherical shape, a sheet shape, and a square prism shape. These different shapes of calcium carbonate can be prepared by controlling the reaction conditions. Its particle size is small, the average particle size is generally 1-3m, and the distribution is narrow. It is hardly soluble in water and alcohol, soluble in acid, and emits carbon dioxide, which is an exothermic reaction. Also soluble in ammonium chloride solution, stable in the air with a slight moisture absorption capacity.

The light calcium carbonate adopts the carbonization method, and the limestone and the white coal are mixed in a certain ratio, and then the high-temperature calcination, water digestion, carbon dioxide carbonization, centrifugal dehydration, drying, cooling, pulverization, and sieving are obtained.

Heavy calcium carbonate is widely used, and it can be filled with rubber to obtain higher tensile strength, tear strength and wear resistance than pure rubber sulfide. It can play a skeleton role in plastic products, has a great effect on the dimensional stability of plastic products, can also improve the hardness of the products, and improve the surface gloss and surface flatness of the products.
