Calcite – Electro Magnetic Industries


Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). It is one of the most important and abundant minerals on Earth. The varieties of calcite are unlimited and they serve numerous purposes, from decorations to common household and building materials to nature’s most exquisite sightings.

Calcite processing flow

Firstly the calcite from quarry will be sent to the primary crusher. After crushing, the small granule will go into the grinding mill and we will get the calcite powder as requested. In the grinding mill, the fineness is controlled by the classifier. Qualified powder could be packaged as the final product, while unqualified powder will go down into the mill chamber.

First stage

The big rock will be crushed by the primary crusher.

Second stage

After crushing, suitable granule will be sent to the MTM or MTW Raymond mill.

Third stage

After grinding, we get the qualified powder. The pulse filter will control the dust emission.

Fourth stage

Package and store the product properly.

Equipment needed

According to the different needs of the industry and calcite processing equipment is slightly different, at present on the market mainstream calcite milling equipment have the European version of the trapezoidal milling machine and Medium Speed Trapezoidal milling machine.

MTW Series Euro-type Trapezium Mill

The milling machine used in grinding and processing of metallurgy, building plastics, fillers, cosmetics, chemicals and other industries……

MTM Series Medium-Speed Trapezium Mill

Widely used electric power, mine, metallurgy, chemical plant, steel, construction, coal, producing a huge economic and social benefits.

Investment prospects

Whether it is heavy calcium carbonate or calcium carbonate, in the oil, metal smelting, chemical synthesis, aerospace, high-temperature superconductivity, machinery manufacturing, ect, high-tech sector in particular has an extremely wide range of applications, especially ultrafine heavy calcium it can be used as the base material of the industrial sector, and therefore the demand is particularly large. Therefore, TSP powder become most upstream industrial manufacturing and raw materials, including almost all of the production and manufacturing sectors of heavy industry. Calcium carbonate is a sunrise industry in the 21st century, with the continuous progress of China’s powder technology, and their applications continue to expand in the future they will play a greater advantage.

Application areas

The Main use of calcite

  • 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. However, because of weathering mainly caused by acid rain, calcium carbonate (in limestone form) is no longer used for building purposes on its own, but only as a raw/primary substance for building materials.
  • GCC is used as a filler in paper because they are cheaper than wood fiber. In terms of market volume, GCC are the most important types of fillers currently used. Printing and writing paper can contain 10–20% calcium carbonate. In North America, calcium carbonate has begun to replace kaolin in the production of glossy paper. Europe has been practicing this as alkaline papermaking or acid-free papermaking for some decades.
  • Calcium carbonate is widely used as an extender in paints, in particular matte emulsion paint where typically 30% by weight of the paint is either chalk or marble. It is also a popular filler in plastics.
