How to produce the calcium carbonate powder applying in the concrete industryPosted: 2016-01-29

  • In the process of production of calcium carbonate gravel and mechanism of sand, a large number of calcium carbonate powders are produced, which not only pollute the environment, but also cause the waste of resources. But the people are little reaching and knowing about that the calcium carbonate powder which is the function in the concrete.

    As everyone knows, the basic components of concrete materials for the cement, sand, gravel, water and additives. Because the Large-scale infrastructure construction in our country. The output of concrete rise greatly and the concrete product develop rapidly. It is caused a phenomenon about lack of mineral admixture resources, and affects the quality, yield and cost of concrete.

    calcium carbonate powder is admixture of concrete, because of its fineness smaller than cement, play a decentralized role in the mixture, and can accelerate the hydration of cement, improve the strength of concrete

    How to produce the calcium carbonate powder
    There are two processes from the raw calcium carbonate to final product-crushing process and grinding process.
    If the raw calcium carbonate is bigger than the input size of your grinding mill, it should be crushed firstly. The proposed calcium carbonate crusher is Jianye impact crusher, which features reasonable structure, high productivity, easy operation and maintenance and safe performance. It can crush the material whose pressure resistance strength is under 350Mpa. The calcium carbonate from the mines is conveyed to the crusher through conveyor. Crusher reduces the size of the calcium carbonate from 1m to –25 mm size. The crushed calcium carbonate will be sent by a belt conveyer to vibrating screen becoming final products or to grinding mill to fine grind. In order to control the emissions from the crusher, a suitable bag filter system will be provided.

    If the raw calcium carbonate is small enough and can be directly grinded by grinding mill, it can be grinded directly. The proposed calcium carbonate grinding mill is MCC YGM series high pressure grinding mill (Raymond mill). If you need high fineness, you can choose micro powder mill, which features high capacity, low consumption, high fineness, flexible adjustment and trustworthy security.
