Calcium carbonate is a compound, Calcium carbonate is a raw material commonly used in the industrial production, the use of calcium carbonate in industry is mainly manifested in the following industries, such as the PVC industry,rubber industry, plastics industry, it can be used as additives in the smelting industry. According to the type of calcium carbonate production process, can be divided into calcium carbonate, heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate, and crystal calcium carbonate.
The raw of Calcium carbonate mineral materials enter the crusher for primary crushing,the calcium carbonate fragments are elevated to the grinding machine host, the analysis machine selected to meet the requirements of the micronized, the powder collector collect the fine powder,pulse dust filter dust.The calcium carbonate production process is very simple,grinding calcium carbonate is the main part of ,the choice of the milling equipment directly determines the status of the production of calcium carbonate in the entire production line, but also determines the quality of the finished product of calcium carbonate powder.
Calcium carbonate milling equipment to determine the performance under the following conditions 1.After being processed by calcium carbonate griding equipment ,whether the calcium carbonate micro powder can reach the fineness requirement . 2.Calcium carbonate milling equipment is easy to operate and maintain 3.Production can meet the needs of the calcium carbonate processing equipment unit time. 4.Calcium carbonate milling equipment must also meet the needs of environmental protection.
Calcium carbonate coating machine for sale in Daswell machinery. Calcium carbonate powder surface coating machine is used to modify the surface of ground calcium carbonate powder. As a result, the property of the ground calcium carbonate powder will be changed. And with unique characteristics, coated calcium carbonate powder can be applied in wide range areas. Usually the machine is added to existing carbonate plant to produce both coated and normal types of calcium carbonate powder. Of course, you can build a new ground calcium carbonate production line with calcium carbonate coating machine. Henan Daswell machinery offers high quality calcium carbonate surface modification machine to produced coated ground calcium carbonate powder in consistent sizes with high activation rate.
Henan Daswell machinery is a leading supplier of ground calcium carbonate plant in China. Daswell can be the single source of complete designing and planning of your calcium carbonate plant. Besides,we also provides high grade equipment for your calcium carbonate production line with crushing, transferring, grinding, classifying, coating and packing system. Daswell calcium carbonate powder coating equipment is an advanced solution for producing coated calcium carbonate powder. In fact, to get more consistent sizes of coated ground calcium carbonate powder, the machine should work together with classifier. Actually, as stated above, the coating machine is often a part of ground calcium carbonate plant so that the calcium carbonate production line can produce both coated and uncoated calcium carbonate. And both the coated and natural ground calcium carbonate powder have many applications in different industries. As a result, the calcium carbonate production line with calcium carbonate surface treatment machine can have great economic value.
According to Wikipedia, powder coating is a type of coating that is applied as a free-flowing, dry powder. More specifically, powder coating is to apply additives to fine powder in order to improve product handling and performance. In the case of calcium carbonate coating, it means to add stearic acid to fine or ultra fine calcium carbonate powder, so that the surface properties of GCC powder can be changed. Initially, the ground calcium carbonate powder is hydrophilic, which can be unfriendly to organics like polymers. However, the plastic industry is also in urgent needs of cheap white filler. If ground calcium carbonate powder is added to plastics, a lot of frictions can occur due to the high surface energy of GCC powder particle. Yet when the surface of GCC powder is modified with steraic acid, the coated calcium carbonate powder become hydrophobic and can reduce the friction when added to plastics.
How to produce stearic acid coated calcium carbonate? Say you have a calcium carbonate grinding plant using a ball mill and classifier for particle size control, and you want to coating this ground calcium carbonate powder with stearic acid, what is the most suitable coating process for your plant. Of course, there is no one for all solution for coating ground calcium carbonate powder. And we can only provide you the suitable approach according to your needs, such as the particle size of GCC powder, the coating thickness, intended use, allowed residuals and so on. The fit solution is to add a coating machine and an air classifier. For this coating system for calcium carbonate powder further allows you to control the particle size of coated calcium carbonate, the coating thickness and so on.
The exact calcium carbonate coating process. Firstly, the GCC powder are mixed with stearic acid through respective feeder. Then the mixture of ground calcium carbonate powder with stearic acid is blown by hot air to the calcium carbonate coating machine. In the machine, the high speed turbo mixer starts to coating the powder in atomization process to reach high coating rate. Then the coated calcium carbonate will go to the air classifier carried by air. In the air classifier, the rejected coated calcium carbonate powder will be returned to coating machine for further coating, while the required coated calcium carbonate will go to the product silo. Of course, there is also dust collector and packing machines in the process.
As stearic acid coated calcium carbonate is hydrophobic, it is more friendly to organics like polymers than ground calcium carbonate powder. As a result, coated ground calcium carbonate powder can be used as filler in plastics for PVC, rubber, decorative paints, slippers, textile and other similar industries. Ground calcium carbonate coating machine in Daswell can produce quality coated calcium carbonate powder with high coating rate, high consistency, controlled particle sizes, and great brightness. As a result, produced coated calcium carbonate can applied in various industries with high economic value.
