1. Introduction of calcite
Calcite is a calcium carbonate mineral, the main component of which is CaCO3. It is usually transparent, colorless or white, and sometimes contains mixed colors. Its Mohs hardness is 3, density is 2.6-2.94, and it has glassy luster. Calcite is widely used in building materials, chemical industry and agriculture etc. What’s the powder processing of calcite?
2. Powder processing of calcite
Powder processing of calcite is generally divided into two types: calcite fine powder processing (200 mesh-400 mesh) and calcite ultra-fine powder deep processing (600 mesh-2500 mesh).
The powder processing of calcite mainly includes the following steps: crushing, grinding, grading and powder collecting.
First step: crushing
First, crush large calcite material into small pieces by a jaw crusher. Then, crush the small pieces by a hammer crusher or an impact crusher. Through these two crushes, the feeding fineness of calcite can be guaranteed (usually 15mm-50mm).
Second step: grinding
After crushing, small pieces of calcite enter ball mill or roller mill for grinding. Through this process, the material can be ground into fine powder.
Third step: classifying
After grinding, calcite powder needs to be classified. Unqualified powder returns to the grinding area for re-grinding.
Forth step: powder collecting
Qualified powder is transported with air flow through the pipeline into dust collector for separation and collection, and collected powder is sent to finished product warehouse through the conveying device and packaged.
3. Summary
Ground calcite has multiple advantages. It can expand application scope, and improve product performance. At the same time, it can also improve environmental protection and economic benefits.
