Question: What is the commonly used material of heavy calcium powder?
Reply：
Dear Dimas,
Heavy calcium carbonate is made from natural carbonate minerals such as calcite, marble, limestone grinding, also known as grinding calcium carbonate, is commonly used powder inorganic filler. The difference of calcium powder between calcite, marble, limestone processing are as follows:
The chemical formula of calcite is CaCO3, its theoretical chemical composition: CaO 56.03%, CO2 43.97%, is a triangular system, colorless or white, sometimes dyed by iron, manganese, copper and other elements into light yellow, light red, purple, brown and so on.
Natural marble is recrystallized limestone, its main component is CaCO3. The limestone softens at high temperature and pressure and recrystallizes to form marble when the contained minerals changed. The main ingredient is calcium and dolomite, usually has clear pattern and a lot of mineral particles. Its Mohs hardness is from 3 to 5, generally in the cube.
The main chemical composition of limestone is CaCO3, with calcite particles, crystal morphology is complex, often triangular facet and rhombohedral, light gray or gray, Mohs hardness is 3 to 4, density is 2.5~2.8g/cm3.
The main components of the three are CaCO3,the calcium content of calcite is slightly higher than marble and limestone, the highest can reach more than 99%. Therefore, not the general limestone and marble can be used as heavy calcium powder raw materials, the high calcium content of limestone can be produced heavy calcium carbonate.
Kefid can provide a full set of crushing, grinding equipment and programs.We have MTW European type grinding mill, TGM overpressure trapezium mill, raymond mill, vertical mill, ultra-fine grinding mill, super fine micro powder mill and other kinds of heavy calcium powder processing equipment to process 200 mesh, 325 mesh, 400 mesh, 800 mesh, 1250 mesh and other different fineness of powder to meet the needs of different application.
Regards!
Kefid
