Chemical synthetic methods and chemical reactions under various conditions, high temperature, high pressure and sudden cold technology to prepare. Nanomaterials generally take a mixed legal system. In the low end of the ultrafine powder production process is relatively simple, the quality of their products to protect the device performance.com. It is also an important goal for the calcium carbonate industrial development in China.mhcmp. Strengthening research and development of new high-grade ultra-fine calcium carbonate’s production technology and equipment is the urgent requirement of rubber, plastics, paper and other industries.

The ultrafine powder production and processing is crucial.The ultra-fine powders with the procession of non-metallic mineralization are: kaolin powder, titanium dioxide, talc, feldspar powder, calcite powder, quartz powder, heavy calcium powder, light calcium powder, fluorite powder, mica, barite powder, graphite powder, gypsum powder, swelling clay powder and so on. There are a variety of food, agricultural, medicinal herbs, other animals and plants powders which is made of organic matter. Shanghai, Guangdong OEM precision casting aluminum frame lamp casting parts and other places have developed several different products of calcium carbonate. According to experts’ estimations, China’s ultra-fine powder processing industry has promising developments., form of mainly dry and water law kinds. Second, chemical synthesis, there is the method on the basis of these two mixed.

The main equipment for the physical preparation of ultrafine powder is a variety of different principles of the mill, classifier, and the collection of equipment, such as jet mill, vibration mill, Raymond mill, ball mill, etc.Now the ultra-fine powders in plastic, rubber, electronics, cables, paints, coatings, abrasives, pharmaceuticals, cosmetics, ceramics, building materials, food processing and household appliances have a great amount of demands.From the 1980s, China has begun the ultra-fine calcium carbonate researches.High and ultra-high grade of ultra-fine boron powder production should have advanced level technology and equipment as protection.At present, the method for the production of ultra-fine powders is mainly two ways: First, the physical methods
