Top 3 Calcium Carbonate Grinding Machines for Ground Calcium Carbonate Powder
Ground calcium carbonate powder has the advantages of good whiteness, high purity, and stable chemical properties. It is one of the most widely used fillers. Ground calcium carbonate powder is widely used in plastics, papermaking, coatings, rubber, building materials, and environmental protection. Therefore, the demand for it is constantly increasing. In a calcium carbonate grinding plant, calcium carbonate grinding is the most important part to determine the quality of the finished product. So choosing a suitable calcium carbonate grinding machine can effectively enhance product quality, boost production efficiency, and reduce energy consumption. There are three types of calcium carbonate grinding machines that can be chosen.
Why Calcium Carbonate Grinding Is the Core of GCC Plant
Calcium carbonate grinding involves processing raw materials into products of various particle sizes through physical grinding. So the final performance of the finished product is determined by the grinding process. The grinding stage accounts for 50% to 60% of the factory’s operating costs.
What factors are influenced by the selection of a calcium carbonate grinding machine?
- Particle size range of the finished powder
- Production energy consumption
- Equipment wear rate and maintenance costs
- The stability and continuity of a calcium carbonate grinding plant
Calcium Carbonate Grinding Process
1. Dry ground calcium carbonate: Dry ground calcium carbonate is the most widely applied and mature method for calcium carbonate grinding production. The raw materials are subjected to physical grinding through a calcium carbonate grinding machine. This process is suitable for producing powders ranging from 80 to 2500 mesh. Dry ground calcium carbonate is simple process, low investment, wide range of applications.
The main process includes: Raw Materials — Crushing — Classification — Dust removal — Packaging.
2. Wet ground calcium carbonate: Wet ground calcium carbonate is added to water or other liquids. Then, a calcium carbonate grinding machine is used to perform ultrafine grinding on the raw materials. Wet ground calcium carbonate is suitable for producing calcium carbonate products with a fineness of 6000 mesh or higher.
The main process includes: Raw Materials — Liquid Medium — Wet Grinding — Dewatering — Drying — Disintegration — Packaging.
