What are the uses of heavy calcium carbonate?

Heavy calcium carbonate is made of natural calcite and limestone, It is mechanically crushed to a certain fineness, mainly used in the production of cement, anhydrous calcium oxide, glass, building materials, etc. It can also be used as filler for plastics, coatings and paints, as well as white filler for rubber and wires.
 
The production methods of heavy calcium carbonate include dry method and wet method. At present, all domestic products are produced by dry method. More than 75% are products with fineness below 400 mesh, and the output of ultra-fine heavy calcium carbonate is only 300000 tons. China also needs to import a certain amount of heavy calcium carbonate products every year.

 

Liming Heavy Industry has complete types and numbers of milling machines, advanced and mature technology. MTW European mill is a new type of grinding equipment developed by Liming Heavy Industry. The whole machine adopts closed-circuit system and vertical structure, which saves energy efficiency and has full production capacity. Since it was put on the market, it has stable performance and good reputation. It is a good choice for you to process heavy calcium carbonate.
