Comparison of the two nano-graphite preparation. Two preparation methods have their advantages and disadvantages. Only in the preparation, production graphite technology innovation, reform Lacey graphite factory, nano-graphite will be faster and better to reach volume production. Through our research and development and innovation mill equipment, production of ultra-fine grinding mill to make graphite, grinding, screening out of nano-graphite, greatly reducing the number of crushing, grinding time to improve two-thirds. Thus, we prepared nano-graphite particles uniformly superior performance carbon graphite, to overcome the traditional disadvantages of nano graphite powder, graphite nano-purpose mass production. Industrial minerals will be divided into crystalline graphite (flake) graphite ore and stable crystalline (earthy) graphite ore into two categories. Crystalline flake graphite ores can be divided into two kinds of compact shape. Flake graphite ore to China crystal type, followed by the Aphanitic type, dense crystalline graphite-like Alexis de Puebla saw in Xinjiang, such as individual deposits, little industrial value. Stable crystalline graphite ores typically in microcrystalline aggregates, the crystal grain size of less than 1μm, only under the electron microscope to observe their crystalline form. Ore grayish black, steel gray graphite milk, usually glossy dark graphite, with dense block, earthy and layered, pp sheet structure. Process performance is better than implicit polycrystalline graphite flake graphite, industrial application is also smaller, ore grades are generally higher, but poor ore optional. Mineral composition of graphite-based, there are associated andalusite, water mica, sericite and minor pyrite, tourmaline, limonite, calcite. Grade is generally 60 to 80%, ash content of 15 to 22%, volatile content of 1 to 2%, a water content of 2 to 7%.
