Daily Capacity 20 Ton CaCO3 Grinding Plant
Calcium carbonate powder is widely used in various fields. According to the different particle size of its powder, its application in different fields is also different. It is generally processed by a calcium carbonate mill or a whole calcium carbonate grinding plant
Limestone, marble, and calcite are common raw materials for calcium carbonate powder processing. So how does the hard stone become calcium carbonate powder?
Calcium carbonate powder grinding plant process
1. Crushing: Usually calcium carbonate processing usually has a large size. Because of the limited size of the input opening, it is impossible to be used for grinding. Such a large stone can be crushed into small pieces. Therefore, the crushing equipment on the calcium carbonate production line is generally recommended to choose a hammer crusher or a small jaw crusher.
2. Lifting: The opening of the calcium carbonate mill is usually at the top of the frame, so the raw materials must be lifted to the top of the machine for feeding. Bucket elevator is a better equipment with a small footprint to ensure smooth feeding.
3. Grinding: The grinding process is the core component of the entire calcium carbonate grinding production line. It usually includes calcium carbonate grinders, analyzers, electromagnetic vibrating feeders, powder separators, etc., along with the role of rollers, Grind the material to a high degree of fineness until it is discharged.
4. Dust removal: This is the last step of the calcium carbonate grinding production line. The grinding production not only causes pollution but also harms the health of workers. Therefore, we are equipped with a high-tech dust removal system to filter out more than 95% of the dust. The dust removal effect Significantly.
How to choose calcium carbonate grinding mill?
Different fineness of calcium carbonate powder requires different processing equipment. The following is the calcium carbonate mill to choose according to the discharge particle size:
HGM micro powder grinding mill: 74-5 micron(200-2500 mesh); D97=5 micron
YGM Raymond mill: 613-33 micron(30-325 mesh); D90=30 micron
CLUM ultrafine vertical roller mill: 20-5 micron(600-3000 mesh); D50=2 micron D97=4 micron
For the choice of calcium carbonate mill, it is generally recommended to choose Raymond mill, because the powder produced by this equipment has a particle size of less than 325 mesh, which can fully meet the demand for calcium carbonate powder in the market, but there is also a need for finer powder For calcium carbonate powder with particle size, HGM micro powder grinding mill or CLUM ultra-fine grinding mill can be selected to meet customer needs. The particle size of the powder can reach 3000 mesh.
