Calcite belongs to calcium carbonate mineral. It is a widely distributed mineral on earth. Calcite crystals are of various shapes, and their aggregates can be clusters of crystals, or granular, fibrous, stalactic and so on. It can be impacted to get many square pieces-this can be the reason why it get such a name. Calcite is the main mineral of limestone and marble, and has many applications in production and life. Many people know that limestone can form karst caves, in which stalactite, stalagmite white jade and so on are actually composed of calcite. Calcite contains Mn, Fe, Zn, Mg, Pb, Sr, Ba, Co, TR and other isomorphic substitutes; when these elements reach a certain amount, they can form manganese calcite, iron calcite, zinc calcite, magnesium calcite and other varieties. In addition, brucite, dolomite, iron hydroxide and oxide, sulfide, quartz and other mechanical mixtures are also common in the crystals.
How can we make large blocks of calcite into powders? This is not complicated. Crushing the large pieces of calcite into small particles by crusher, and then grinding the particles by using calcite grinding mills to achieve the purpose of ore pulverization.
Calcite is found in limestone mines and widely exists in Tertiary and Quaternary limestone and metamorphic rock deposits. It accounts for more than 40% of the total crust of earth, and its species is not less than 200 species. They are distributed in China, Mexico, Britain, France, the United States, Germany. Calcite in China is mainly distributed in Guangxi, Jiangxi and Hunan. Guangxi is famous for its high whiteness calcite in domestic market.
There are three represented calcite grinding machines in Shanghai Clirik Machinery- Calcite Raymond mill, calcite ultra-fine grinding machine and calcite ultra-fine vertical mill.
Here, let us focus on the ultra-fine calcite grinding machine. Our company has prepared the micro powder packing machine for the customers. This powder packing machine has two types: valve type and opening type. It adopts the technology of frequency controller and electronically automatic measurement.
