A Calcite Grinding Plant is an industrial facility that processes naturally occurring calcite (calcium carbonate - CaCO₃) into micronized or fine powder form suitable for various industrial applications. The plant transforms raw calcite rocks into high-purity, ultra-fine powders used in multiple sectors.

Calcite is one of the most abundant and economically valuable carbonate minerals, especially found in limestone and marble deposits. When ground, it becomes a key ingredient in modern industries.

 WHAT DOES A CALCITE GRINDING PLANT DO?

The main functions of a calcite grinding plant include:

  • Crushing large calcite stones

  • Grinding into fine/micron-sized powder

  • Classifying and drying the powder

  • Packaging into different weights (e.g., 25 kg, 50 kg, bulk)

Micronized calcite is widely used in:

  • Paint industry (white pigment and extender)

  • Plastics (filler in PVC, PE, PP)

  • Paper manufacturing (surface smoothness and whiteness)

  • Ceramics (ingredient in glazes and tiles)

  • Agriculture (soil pH stabilizer)

  • Construction (additive in mortars and adhesives)

  • Food and pharma (calcium supplement)

 HOW DOES A CALCITE GRINDING PLANT WORK?

1. Feeding and Crushing Unit

Raw calcite rocks are crushed using jaw and cone crushers into smaller fragments.

2. Grinding Unit

The material is further ground using ball mills, hammer mills, vertical mills, or jet mills to achieve the required particle size (e.g., 5–20 microns).

3. Classification

Using air classifiers and cyclones, the powder is sorted into precise size ranges.

4. Drying and Packaging

The fine product is dried to remove residual moisture and packaged for storage or shipment.

 WHERE IS CALCITE POWDER USED?

  • Paints & Coatings: Improves brightness, acts as a filler

  • Plastics: Increases volume and reduces costs

  • Paper: Enhances smoothness and brightness

  • Ceramics: Ingredient in glaze formulations

  • Agriculture: Neutralizes acidic soils

  • Construction: Used in wall putties and plasters

  • Pharmaceuticals & Food: As calcium additive (food grade)
