Introduction
Calcium carbonate, commonly known as limestone, stone powder, marble, etc. It is an inorganic compound, the main component is calcite, which is basically insoluble in water and soluble in hydrochloric acid. It often exists in calcite, chalk, limestone, marble and other rocks. It is also the main component of animal bones or shells. According to different production methods, calcium carbonate can be divided into heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate. Among them, heavy calcium is refined by directly crushing calcite, limestone, chalk and shell by mechanical method, which has important applications in industrial production.
Raw material testing
The particle shape of heavy calcium is irregular. It is a polydisperse powder with an average particle size of 5-10 μ m。 The application fields of powders with different fineness are also different. For example, the powder within 200 mesh can be used for various feed additives, with a calcium content of more than 55.6 and no harmful components. 350 mesh - 400 mesh powder can be used to manufacture gusset plate, downcomer pipe and chemical industry, and the whiteness is more than 93 degrees. Therefore, doing a good job in the detection of heavy calcium raw materials is an important measure about the application prospect of heavy calcium. Guilin Hongcheng has rich experience in the field of heavy calcium pulverization and has superb and precise testing instruments and equipment, which can help customers analyze and test raw materials. It includes the finished product inspection of particle size analysis and product passing rate, so as to help customers carry out market development in different fields according to different particle sizes with real and reliable analysis data, so as to more accurately locate the market development direction.

Environmental protection measures
1. It adopts pulse dust collection system to collect dust efficiently, with an efficiency of more than 99%. It effectively prevents the long-term backlog of powder. It is one of the patents invented by Hongcheng in compliance with the requirements of environmental protection;
2. The system is sealed as a whole and operates under full negative pressure, which can basically realize no dust overflow;
3. The system has few equipment and simple structural layout, which is only 50% of the ball mill. And it can be open-air, which greatly reduces the floor area and construction cost, and the return of funds is fast;
4. Low energy consumption, which is 40% - 50% lower than that of ball mill;
5.The whole system has small vibration and low noise. The utility model adopts a grinding roller limiting device, which can effectively avoid violent vibration and has more reliable performance.
Return on investment
At present, calcium carbonate has high application value in papermaking, plastics, rubber, paint, medicine and other industries. The high application of heavy calcium powder in the market mainly includes 325 mesh, 400 mesh coarse powder, 800 mesh micro powder, 1250 mesh and 2000 mesh ultra-fine powder. The introduction of advanced milling technology and equipment can not only process calcium carbonate efficiently, but also further improve the grinding efficiency, improve the added value of products, help enterprises improve the core competitiveness of products and produce greater economic and social benefits.
