Calcium carbonate production line is to produce calcium carbonate powder by grinding basic material such as limestone or marble. And the calcium carbonate plant includes a complete set of calcium carbonate manufacturing equipment. For example, there are crusher, vibrating feeder, elevator bucket or belt conveyor, calcium carbonate grinding mill, air classifier, silos, dust collector, calcium carbonate coating machine, packing machines and so on. Daswell manufactures and supplies complete set of calcium carbonate grinding plant machinery with high quality. And all these machines are designed and manufactured according to customers’ specific requirements.
Calcium Carbonate Manufacturing Process
Firstly, the quarried limestone will be crushed in primary and secondary crusher to proper sizes. Then the limestone will go through vibrating screen to reject unqualified limestone. And then the feed limestone will be transferred to product silo through bucket elevator. Through vibrating feeder, feed limestone is metered into calcium carbonate grinding mill. In the grinding mill, feed limestone is ground to fine and even ultra fine calcium carbonate powder. To get more fine and ultra fine ground calcium carbonate powder, the calcium carbonate powder from grinding mill can go through air classifier. If you want to get coated calcium carbonate, you can direct the calcium carbonate powder into the calcium carbonate coating machine. And then the natural and coated calcium carbonate powder will go through dust collector. And finally the final product will be packed.
Calcium Carbonate Crushing Equipment
Quarried limestone is often too big to feed into calcium carbonate grinding mill. Besides, different calcium carbonate grinding mill have different feed material required sizes. So there is great need of primary and even secondary crushers. Usually, the jaw crusher is used to crush the basic materials such as limestone or marble. And there is also vibrating screen to screen the qualified sizes of feed material.
Calcium Carbonate Grinding Mill
Calcium carbonate grinding mill is the central equipment for calcium carbonate manufacturing plant. And there are many kinds of calcium carbonate grinders available, such as ball mill, roller mill, vertical mill, wet grinding mill and so on. Since different grinding mills have different capacity and diameters, Daswell can help you to choose the best suitable one for your calcium carbonate grinding plant. And there are several factors to be considered, such as raw material property, desired fineness, production capacity and so on.
Ground Calcium Carbonate Air Classifier
Calcium carbonate air classifier is used for further cut of calcium carbonate powder. After being ground in calcium carbonate grinding mill, the calcium carbonate powder will be transferred into air classifier. In there, the air flow inside will carry the lighter powder upward and get further cut, while the coarse ones will fall down due to gravity. Calcium carbonate grinding mill and air classifier together can produce fine and ultra fine calcium carbonate powder.
Calcium Carbonate Powder Dust Collector
To protect environment as well as the safety of employees, calcium carbonate grinding plant will be equipped with dust collector. Of course, Daswell offers several kinds of dust collectors to ensure the dust free working environment.
Calcium Carbonate Coating Machine
Calcium carbonate coating machine is used to coating calcium carbonate powder with stearic acid. And to obtain coated calcium carbonate, you can simply add a calcium carbonate surface treating machine to your calcium carbonate plant. As a result, your calcium carbonate grinding plant can both produce natural calcium carbonate powder as well as coated calcium carbonate powder, which make more economic value for you. For both uncoated and coated calcium carbonate powder are very useful minerals in many industries, such as paper, paint, plastic and other industries. Daswell calcium carbonate coating machine are made of high quality material to work long time and they can produce high quality coated calcium carbonate powder with great consistency and uniform.
Calcium Carbonate Powder Packing Machine
Daswell offers mainly two kind of calcium carbonate powder packing machine according to automatic style. One is semi automatic and the other is fully automatic. As the name implies the semi automatic calcium carbonate packing machine still needs human labor to finish the packing process. While fully automatic calcium carbonate packing machine needs no more human labor and can pack and transfer bags of calcium carbonate powder to set area. Besides, there are also valve mouth packing machine and ton bag packing machines available. And no matter which kind of Daswell calcium carbonate packing machine you choose, they are of robust designs and built to work for long service time. What’s more, they are both efficient and accurate when handing calcium carbonate powder.
Calcium Carbonate Plant Control System
As stated above, there are many machines for a calcium carbonate production line. And the smooth operation of the calcium carbonate plant depends on the well operation of each piece of equipment. For great convenience and efficiency, the calcium carbonate manufacturing plant is equipped with computer control system. With this system, employee can monitor the whole calcium carbonate manufacturing process, and make adjustment easily.
