Heavy calcium powder is the abbreviation of heavy calcium carbonate, which is relatively stable in the air. Heavy calcium powder is ground by natural carbonate minerals, It is a commonly used powdery inorganic filler, Grinding of natural carbonate minerals such as calcite, marble, limestone by a pulverizer. The fineness requirements of heavy calcium powder for different purposes are different.
1.Heavy calcium powder in dry mortar and concrete for the construction industry.
The dry powder mortar uses 325 meshes of heavy calcium powder, and the whiteness requirement is 90%. It can be processed by Raymond mill, The calcium carbonate content is 95%. Calcium carbonate plays an important role in concrete in the construction industry. Raymond mill can grind more than 300 kinds of materials in the construction industry. The particle size of the finished product is adjusted within the range of 80-325 meshes, which can not only reduce the production cost, but also increase the toughness and strength of the product.
2. Requirements for the use of water-based coatings industry.
Heavy calcium carbonate powder used for water-based coatings has more than 800 meshes, Whiteness: 95%, calcium carbonate: 96%. Calcium carbonate is more widely used in the water-based coating industry. The particle size of micro powder grinder is relatively fine, and it is also mainly used for processing gypsum, calcite, talc, coatings, etc. the applicable materials are non flammable and explosive non-metallic materials with Mohs hardness below 9.
3. The fineness requirements of heavy calcium powder for engineering home decoration paint.
Heavy calcium carbonate for paint emulsion paint is more than 800 mesh, Whiteness: 95%, calcium carbonate: 96%. Ultra fine vertical grinder can be used for powder grinding, deep processing of slag powder. Calcium carbonate is also used in the paint industry, for example, in thick paint, the dosage is more than 30%.
4. The rubber industry uses heavy calcium powder for analysis.
Heavy calcium carbonate powder for rubber: more than 400 meshes, Whiteness: 93%, depending on the situation of the rubber material, the whiteness requirements can be reduced. Calcium carbonate is widely used in the rubber industry, which can increase the volume of its products and save expensive natural rubber. The discharge particle size of the LUM ultra-fine vertical mill is 400 - 650 meshes, and the output range is 5 - 18 T / h. The processed heavy calcium carbonate powder can improve the tensile strength, tear strength and wear resistance of the rubber.
5. Fineness requirements used in artificial marble industry.
Heavy calcium powder for artificial marble: 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5% when it is pure and free of impurities. Calcium carbonate has been widely used in the production of artificial marble. Raymond mill or vertical mill can meet this industrial demand and obtain better powder.
The choice of the type of heavy calcium mill depends on the specific use. Different industries have different requirements for the fineness of heavy calcium powder. How to choose the type of mill is particularly important, because it affects the use effect in different fields. Therefore, in the early stage of putting into use, we must do a good job of investigation and analysis, so as to improve the efficiency of the production line of heavy calcium powder and speed up the progress of the project.
