What is Calcite
Calcite is the one of the most common minerals. It occurs in a great variety of shapes and colors, and it constitutes a major portion of many of the earth's rocks.
Calcite is the primary ore of calcium. Calcite is indispensable in the construction industry, forming the base of cement. Many important chemicals are created from Calcite, as well as useful drugs. It is also crucial in the manufacture of fertilizers, metals, glass, rubber, and paint. The transparent Iceland Spar variety, in which the double refraction is very apparent, was used as prisms for polarizing microscopes and other optical devices.
Calcite also forms rocks that are used for ornamental purposes, such as marble and banded travertine or tufa. Calcite is also the main component of chalk, which is processed for drawing chalk. To collectors, Calcite is one of the best-known and most commonly collected minerals. Most specimens are inexpensive except for those of exceptional size and crystal form, or from classic occurrences
The processed calcite powder can be used as industrial raw materials such as chemical industry and cement. It is used as a flux in the metallurgical industry and in the construction industry to produce cement and lime.
Uses of Calcite in Construction
The construction industry is the primary consumer of calcite in the form of limestone and marble.
These rocks have been used as dimension stones.
Modern construction uses calcite in the form of limestone and marble to produce cement and concrete.
These materials are easily mixed, transported, and placed in the form of a slurry that will harden into a durable construction material.
Concrete is used to make buildings, highways, bridges, walls, and many other structures.
Process Flow Of Calcite Grinding
Calcite belongs to the type of ore that is easy to grind. Calcite grinding powder generally requires the fineness of the finished product to be small.
Grinding: The crushed calcite (≤30mm) is lifted to the silo by the elevator and sent to the grinding chamber of the mill for grinding. Under the action of the grinding roller and ring, the material is crushed.
Grading: The milled powder is classified by the powder separator. The unqualified powder is classified by the powder separator and then returned to the main engine for re-grinding.
Collecting: The calcite powder that meets the fineness flows into the cyclone collector with the wind. After collection, it is discharged through the powder discharge pipe to be the finished product.
Which Mill Is Suitable For Calcite
The mill is the key machine in the calcite grinding plant. Common calcite grinder includes ball mill, Raymond mill, vertical roller mill, etc. Of course, you maybe want to read:

Calcite Ball Mill
If grinding 35-200 mesh calcite coarse powder, use a ball mill. The particle size of the ground product is coarse and the output is large. However, the ball mill is a horizontal structure, covering a large area, and the overall investment is greater than the Raymond mill.
Calcite Raymond Mill
If grinding 80-325 mesh calcite fine powder, use a Raymond mill. The equipment has a simple structure, advanced technology, low consumption, and environmental protection. It is deeply welcomed by the market.
Vertical Roller Mill For Calcite
LM vertical roller mill is optimized and designed by fully combining the characteristics of calcite. It integrates crushing, drying, grinding, and grading conveying. During operation, the roller sleeve and the liner are not in direct contact, which greatly reduces the iron content in the product. It is used for grinding white or transparent calcite, which effectively improves the whiteness and purity of the product.
