Calcium Carbonate Complete Production Plant

Calcium carbonate production is a relatively complex process. It involves several processing operation and technology including quarrying, mining, crushing, grinding, screening, processing, separation, and calcining etc.

Calcium Carbonate Applications

There are mainly three types of calcium carbonate-containing rock are excavated and used by industry, including limestone, chalk and dolomite. Limestone and chalk are both forms of calcium carbonate and dolomite is a mixture of calcium and magnesium carbonates. These two types of calcium carboante rock both contain impurities such as clay but some rocks are over 97% pure. Limestone and other products derived from it are used extensively in the construction industry and to neutralise acidic compounds in a variety of contexts. For final applications, both of them need to be processed by calcium carbonate complete production plant.

In the construction industry

Limestone has been used as a building material since the Stone Age. Indeed, the largest use of limestone and the various forms of lime is still in the construction industry, particularly in road building and building projects, from vast in size, bridges and skyscrapers, to houses. Large lumps of calcium carbonate are often used where sizeable quantities of aggregate are needed, for example for the foundations of roads. Lime is often used to make soil firmer. It reacts with clay minerals in the soil to form cement-like compounds.

In cement making

Cement is made by heating a mixture of limestone and substances such as clays in kilns at high temperatures until it almost fuses. The mixture is then cooled and ground to a fine powder and mixed with calcium sulfate (gypsum). This is cement. It is essentially a mixture of calcium aluminosilicate and calcium sulfate. When it is mixed with water, chemical reactions occur to form a hard solid, impervious to water.

About 3.6 billion tonnes of cement is produced annually, of which China accounts for 2.1 billion tonnes. Cement powder is usually mixed with sand and aggregate (gravel, granite) and when needed, they are mixed with water to form concrete. Calcium carbonate processing machine will be involved in the operation.
