The calcium carbonate applied in industry is mainly extracted by mining or quarrying. Pure calcium carbonate especially for food or pharmaceutical use can be produced from a pure quarried source usually marble.
Alternatively, calcium carbonate is processed by calcining crude calcium oxide. Water is added to give calcium hydroxide, and carbon dioxide is passed through this solution to precipitate the desired calcium carbonate, referred to in the industry as precipitated calcium carbonate.
As a professional calcium carbonate production line supplier, SBM provides various types of calcium carbonate quarrying plant and mining equipment for sale.
Calcium Carbonate Grinding Mill
The main use of calcium carbonate is in the construction industry, either as a building material or limestone aggregate for road building or as an ingredient of cement or as the starting material for the preparation of builder's lime by burning in a kiln. Calcium carbonate is also used in the purification of iron from iron ore in a blast furnace.
For final application, the calcium carbonate or limestone material must be crushed and pulverized for size reduction. Calcium carbonate grinding mill is available with different types for producing various particle sizes, including ball mill, Raymond mill, high pressure mill, trapezium mill, ultrafine mill, coarse powder mill, vertical mill etc.
Calcium Carbonate Production Line
Calcium carbonate is widely applied in many industrial applications. Calcium carbonate production is a relatively complex process. It involves several processing stage and technology including quarrying, mining, crushing, grinding, screening, processing, separation, and calcining etc.
