LXJM HEAVY CALCIUM CARBONATE POWDER QUALITY ULTRA-FINE GRINDING MILL EQUIPMENT FOR SALE

Heavy calcium carbonate is abbreviated as heavy calcium. It uses high-quality limestone as raw material and is processed into white powder by a lime mill. Its main component is CaCO3. Heavy calcium has the characteristics of high whiteness, good purity, soft hue and stable chemical composition. Heavy calcium is usually used as a filler, widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, fo

Application of heavy calcium carbonate powder

Because calcium carbonate is rich in resources, widely distributed, and simple in processing technology, it has low price, high purity (content up to 98-99%), high whiteness (up to 94%), low oil absorption, low hardness, and good dispersion. Good thermal stability (will not decompose below 400) and other excellent characteristics, so it is widely used in industrial fillers.


1. Plastic

Adding heavy calcium powder to plastics can play the following roles: increase the cost to reduce the cost; improve the heat resistance of plastic products; improve the astigmatism of plastics for shading and matting; improve the electroplating performance or printing performance of plastic fabrics; To reduce the dimensional shrinkage of plastic products, it should be dimensional stability.

The broken ratio is big. Feeding non-metallic mineral particles with a particle size of<10mm can be processed into fine powder of <10μm (under the pass rate of 97%) at one time, and the fine powder of -3μm accounts for about 40%, with a large specific surface area. It has the advantages of high-speed impact mill to produce powder and low consumption,

and it has the product fineness close to jet mill.

Environmental protection. The pulse dust collection system (patent:CN200920140944.3)

has a dust collection rate of over 99.9%,ensuring dust-free operation in the workshop. 

Thorough dust removal: The pulse dust collection system adopts a pulse-jet dust removal method, which uses compressed air  to clean each filter bag separately. The cleaning 

kinetic energy is higher and more thorough, thereby preventing the long-term backlog of 

powder. The powder is on the filter bag for a long time. 

Retention and clogging of the filter bag.

Forced turbine classification technology (patent: ZL201030143470.6), the finished 

particle size can be adjusted between 45μm and 5μm.

WORKING PRINCIPLE                                                                                                                                                                                                                                      


The grinding roller mounted on the rotary table in the main machine chamber rotates around the central axis, and there is a large gap between the grinding roller and the grinding roller pin. Under the action of centrifugal force, the grinding roller swings horizontally outward, so that the grinding roller compacts the grinding ring, and the grinding roller rotates around the grinding roller pin at the same time. Through the gap between the grinding roller and the grinding ring, the material can be crushed and ground by the grinding roller. The grated powder falls to the chassis under the action of gravity and is blown to the classifier above the main engine for screening under the action of a blower. The air path is circulating, except for the positive pressure from the blower to the grinding chamber, the gas in other pipelines flows under negative pressure. The material contains water, which evaporates into gas when it is heated during grinding. The air entering into the gas at various joints in the pipeline leads to the increase of the air volume in the circulating air path. The increased air volume is discharged into the atmosphere through the bellows interface between the blower and the main engine.

HEAVY CALCIUM CARBONATE POWDER PRODUCTION PROCESS                                                                                                                                                          


1. Crushing of raw materials

The large pieces of heavy calcium carbonate are crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

 

2. Grinding

The crushed small pieces of heavy calcium carbonate are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.

 

3. Classification

The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-grinding.

 

4. The collection of finished products

The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow. The collected finished powder is sent to the finished product silo through the discharge port by the conveying device, and then is packaged by a powder tanker or an automatic baler.
