Calcium carbonate
The vast majority of calcium carbonate used in industry is extracted by mining or quarrying. Pure calcium carbonate (such as for food or pharmaceutical use), can be produced from a pure quarried source (usually marble). Alternatively, calcium carbonate is prepared from calcium oxide. Water is added to give calcium hydroxide then carbon dioxide is passed through this solution to precipitate the desired calcium cIn calcium carbonate processing plant, grinding mill is the core equipment to process raw calcium carbonate into powder.

Stone Pulverizer Machine for Calcium Carbonate
The calcium carbonate pulverizer machine is specially developed and manufactured for the characteristics of calcite. The processing process is completely in line with the requirements of calcite micropowder, mainly in: 1. The utilization rate of the other side is high, and the equipment itself will not consume any raw materials.Chemical Properties. From a chemical standpoint, Calcium Carbonate is a base that reacts with acids to form calcium salts, water, and carbon dioxide. Its solubility in water is quite low, but it dissolves in acid, producing a solution of calcium ions, water, and carbon dioxide gas.

Decarbonisation of calcium carbonate at atmospheric temperatures
Moreover, further alternatives to calcination and decarbonisation of calcium carbonate are necessary to improve industrial sustainability. Nonetheless, Ellis et al. 15 showed that Ca(OH) 2 can be used to produce alite, the main mineral in traditional Portland cement, at standard cement clinkering temperatures.A complete of calcium carbonate plant includes crusher machine, grinding mill, air classifier, large surface area, high stability and required fineness.

Environmentally sustainable processes for the synthesis of
Red algae (C. officinals) was used to make HA at low temperature and pressure. The high content of calcium carbonate it contains was extracted via pyrolysis at temperatures ranging between 650 °C–700 °C for 12 h. Granular shaped HA was produced by reacting to the CaCO 3 obtained with ammonium dihydrogen phosphate [NH 3 PO 4 The crystalline phase of calcium carbonate is generally in the form of calcite, aragonite, and vaterite. The different morphological forms are due to different synthesis conditions [ 37,38 ]. Calcite has stable structures, mechanical properties, and thermodynamic properties, so it is widely used in biomedical applications [ 39 ].Synthesis and Characterization of Calcium Carbonate Obtained

What is the use of calcite, what equipment is used to make calcite
Calcite is a carbonate mineral with a Mohs hardness of 3, glass gloss, a density of 2.60-2.8g/cm3, and white streaks. Different deep processing techniques will have different application fields. In the process field, calcite can be used to make cement, calcium carbide, polishing agent, and sometimes as a co-solvent.Calcium Supplements: Calcite is a natural source of calcium, and calcium carbonate derived from calcite is used in dietary supplements and antacids to provide calcium to the body. In summary, calcite’s wide range of industrial and practical uses highlights its importance in various fields, from construction and manufacturing to Calcite : Properties, Formation, Occurrence and Uses Areas
