Calcite, widely distributed, hardness 2.7-3.0, specific gravity 2.6-2.8, also called stalactite, stalagmite white marble and so on. The main component of calcite is calcium carbonate, the main purpose is to make heavy calcium powder and light calcium powder.
Calcite Processing Technology
- Crushing: Large pieces of calcite are crushed by the crusher to the fineness of the feed calcite (15mm-50mm) that can enter the mill.
- Grinding: Small pieces of calcite that meet the conditions for entering the mill are uniformly and quantitatively fed into the grinding chamber of the mill through the feeding system, and ground into powder in the grinding cavity.
- Classification: the ground calcite will be classified by the classifier along with the airflow of the system, and the unqualified powder will be classified by the classifier and then returned to the main grinding cavity for re-grinding.
- Powder collection: The powder that meets the fineness enters the powder collection system with the air flow through the pipeline, and the gas and powder are separated. The finished powder is sent to the finished product silo by the conveying device, and then is packaged by a powder tanker or an automatic baler.

Calcite Fineness And Application
| Fineness | Applications | Recommended Equipment |
| Below 325 meshes | 325 meshes of calcite is commonly used to produce putty powder. It can also be raw materials in chemistry and cement industry. For metallurgy, calcite can be solvent; for construction, materials to produce cement and lime; for food, the additives. Besides, the filling of calcite can make glass semitransparent so it can be used in lampshade production. | MTW Trapezium Mill |
