As a calcium carbonate production plant supplier, Daswell offers turnkey solutions for calcium carbonate manufacturing plant, including plant designing, planning and supplying of calcium carbonate processing plant machinery.
With rich experience and rich knowledge, Daswell has finished several successful calcium carbonate manufacturing plant projects around the world. And to build a best suited calcium carbonate grinding plant for customers, Daswell will first consult the specific needs of customers in property of raw materials, desired fineness, production capacity, energy consumption and so on. Then our professional team will do feasible study of the plant project and come with detailed and tailored calcium carbonate processing plant project report. With customer needs in mind, Daswell is the one source supplier for your calcium carbonate manufacturing plant.
In a calcium carbonate manufacturing plant, there are many machines involved. For example, there are primary and secondary crushers, granules processing device, ball mill and classifier system, dust collectors, packing machines, truck loading stations and so on. And to make coated calcium carbonate powder, calcium carbonate coating line with coating machine and classifier is also needed. Daswell machinery manufactures and supplies quality calcium carbonate grinding plant equipment. The machines are all of robust designs with quality material so that they can work for long period of time. For the specific diameters of machines for calcium carbonate processing plant, they are designed and manufactured depending on the specific needs of customers, such as production capacity, desired powder fineness and so on. Daswell calcium carbonate processing plant with ball mill and classifier can produce calcium carbonate powder with fineness 3.5-23m, 10000 ton/year to 200,000 ton/year.
At first, the quarried limestone is crushed to proper sizes in primary and secondary crusher so as to feed in the calcium carbonate grinding mill. Then the limestone will go through the granule processing stage, rejecting the unqualified ones. And then the proper sizes feed limestone will be transferred to raw material silo through bucket elevator. From the silo, controlled amount of feed limestone will be fed into the calcium carbonate grinding mill. The ball media in the rotating ball mill will impact the feed limestone and grind it to desired fineness. Of course, the fineness of the final powder can be controlled by the rotating speed and the amount of ball media inside the ball mill. Then from the ball mill, the ground calcium carbonate powder will be transferred to classifiers to further cut its sizes, while rejecting coarse ones for further grinding. At last, the final calcium carbonate powder will be stored in product silo waiting for packing. If you want coated calcium carbonate, you can direct the calcium carbonate powder from ball mill into calcium carbonate coating machine. In the machine, stearic acid and calcium carbonate powder will be thoroughly blended and produce the uniform coated calcium carbonate. For desired fineness, the coated calcium carbonate will also go through air classifiers.

daswell calcium carbonate coating machine - coating line for gcc plant
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. So if you want to treat the surface of fine ground calcium carbonate powder, please contact Daswell for more information about our calcium carbonate coating machine.
