Calcium carbonate grinding production line
Calcium carbonate is commonly known as graystone, limestone, stone powder, marble, etc. After crushing and processing, it can be used in construction materials, plastics, coatings, putty, plywood, paint, rubber, metallurgy, papermaking and other fields.The manganese carbonate mineral is a kind of manganese ore and is a metal ore.
Manganese carbonate is a raw material to produce electrolytic manganese metal, and is also used to produce magnetic conductive materials. The beneficiation is mainly based on flotation and strong magnetic separation, and can also be selected by a combination of various methods.
Different fineness calcium carbonate powder has different application fields. According to the different crushing fineness, the industry is divided into four different specifications: single fly, double fly, three fly, and four fly, which are used in various industrial sectors.
What kind of equipment is used to crush manganese carbonate ore?
Before the selection of fine powder, the original ore needs to be crushed first. For metal ore such as manganese carbonate ore, we generally need coarse crushing + fine crushing + grinding.
1.Coarse crushing
The jaw crusher is usually used. its structure is simple, the crushing ratio is large, and the crushing ability is strong. The bulk ore can be crushed to medium grain size at one time.
2. Fine crushing
For high-hardness metal ore such as manganese carbonate ore, the cone crusher is an ideal choice for further crushing the coarsely crushed ore.
The fine crushing of manganese carbonate ore is generally divided into two sections, one section is mainly medium crushed, and a standard type cone crusher can be adopted. The feed port is large and the discharge is 20 mm or more. In the fine crushing process, short head type cone crusher can be used. The machine can control the fineness well, so that the discharge can reach 13mm or less, and the current can reach 6mm. kefid hst single-cylinder hydraulic cone crusher and hpt multi-cylinder hydraulic cone crusher are classic configurations, and many metal mines adopt this configuration.
The finely crushed material is ground into fine powder in ball mill, and then the fine powder is selected, so that a complete set of processing steps is completed.
What is the technical process of calcium carbonate mill?
It is generally classified according to the type of application machine. calcium carbonate is processed into coarse powder (0-3mm), fine powder (80-425 mesh), ultra-fine powder (400-1250 mesh), and fine powder (1250-3250 mesh).
The 400 mesh calcium carbonate mill is between fine powder and superfine powder. You can use general fine mills, such as: vertical mill, mtw european version mill, raymond mill, tgm trapezium mill and other equipment for processing; you can also choose ultrafine mills, such as: lum ultrafine vertical mill, hgm ring roller micron mill, used for ultrafine calcium powder processing over 400 mesh.
The process of calcium carbonate mill:
1.Crushing
Big material is crushed by the crusher to the feed fineness (15mm-50mm) that can enter the mill.
2.Grinding
The crushed small piece of material is sent to the silo by the elevator, and then it is evenly and quantitatively sent to the grinding chamber of the mill for grinding by the vibrating feeder. The ground material is classified by the classifier, and the unqualified powder is classified by the classifier and returned to the host for re-milling.
3.Packaging
Fine powder that meets the fineness will enter the dust collector through the pipeline to be separated and collected. The collected finished powder will be sent to the finished product bin by the delivery device through the discharge port, and then packed with a powder tanker or automatic baler.
Calcium carbonate ultrafine mill
The ultrafine grinding mill can be used in many kinds of materials' grinding production line. The calcium carbonate is the main material involved in mineral ore material and it can be used to be grinded by ultrafine grinding mill and then used in many other applications. Here will analysis the grinded calcium carbonate application.
Ultrafine grinding mill application
The calcium carbonate grinded by ultrafine grinding mill can be used in the following industries: rubber industry, plastics industry, coating industry, paper industry, building industry of dry powder mortar and concrete manufacturing industry as well as fire protection industry and so on. Calcium carbon used in different industries has different requirements.
Calcium carbonate used in different industries
Rubber industry: the grinded calcium carbonate can be used in rubber industry and the fineness is 400mesh. Used in this industry, calcium carbon can increase rubber's volume and improve the rubber processing characteristics. It will play half-reinforce and reinforce function. At the same time, the calcium carbon used in rubber industry can adjust the hardness of rubber and increase its durability.
Plastic industry: when the calcium carbon grinded by ultrafine grinding mill into 400mesh, it can be used in plastic industry. Calcium carbon can increase plastic products stability and the hardness. It can make the plastic more beautiful and durability for improving the plastic products surface gloss and evenness.
Water paint industry: ultrafine grinding mill can grind the calcium carbonate into 800mesh or 1000mesh and this powder can be used in water paint production. It will make the paint has good gloss.
Paper industry: grinding calcium carbonate into 325mesh powder and they can be used in paper making industry. This calcium carbonate can guarantee paper strength and reduce the costs.
Building industry: it can be used to produce dry-mixed mortar and concrete. It can reduce the operation costs and increase products hardness.
Fire protection industry: grinding the calcium carbonate into 600mesh and it can be used in fire protection industry. It can enhance ceiling whiteness and brightness and make the products more beautiful.
