Calcite is widely distributed as a calcium carbonate mineral. Its crystal shape is varied, including granular, massive and fibrous. The color of calcite varies due to its different impurities. In general, calcite is white or colorless. When it contains iron and manganese, it will appear light yellow, light red and other colors.
Calcite is the most important carbonate mineral, and its chemical composition is mainly CaCO3. It belongs to the triangular system, has complete rhombohedral cleavage, showing a glass luster. Calcite has a hardness of 3. Pure and transparent calcite is usually called Iceland spar. Iceland spar is often applied to polarizing prism because of its birefringence. If it is cut into columnar in a certain way, it can be used only as a prism for a microscope. Calcite can be used in chemical, cement and other industrial raw materials after crushing and grinding.Besides, this can also be used as flux in metallurgical industry.
There is no doubt that the requirements for calcite powder are different because of its different usage. One of the most crucial factor of calcite powder is its powder fineness. This means that the various models of talc grinding machine could come in handy.
Raymond mill, the widely used grinding equipment, can make the output powder between 30 and 425 mesh.
Superfine grinding mill distinguished itself from other grinding machines by its high output powder fineness. It can make the final powder reach between 325 and 2500 mesh.
