Ce Approved Superfine Synthetic Graphite Spheroidization Grinding MillWork PrincipleAir classifier mill material would be conveyed by feeding system evenly to milling chamber,and would be impacted by high-speed rotating beater,and also under the centrifugal force,it would impact the grinding track.By several different pulverization powers,the material would be milled into fine powder.The milled powder would go with air flow up to the classifying chamber.With the help of adjustable classifier wheel.coarse powder and fine powder would be separated.Qualified fine powder would be go through the wheel vane then into the cyclone separator or dust collector.while mixture of coarse powder and fine powder would fall down to the milling chamber to be milled again.Main purposeThis applies to the following seven non-metallic mineral hardness, diatomite, fluorspar, Fluorite, mica, and Low humidity, high melting point, viscosity of sulfur Juan, pesticides, and other ultra-fine grinding of Materials to solve the major problem which current domestic crushing industry can not solve. Fineness Can reach at 5 to 10 microns.

Spherical Graphite Introduction
FAQ1.What material you want to grind,is it dry, what is the size of feed material?
- Spherical graphite is produced through fine grinding, purification and spheritisation - processing the flat flake into a sphere of concentrate
- Purification is generally conducted via an acid wash treatment which takes a raw material of approximately 94% TGC to over 99% TGC purity
- Purified product is milled to reach an average commercial size of between 10 and 20 microns, with the ultimate objective of maximising the surface area of the material. Flake graphite can be spheritised to as low as 5 microns
- Uncoated spherical graphite material is usually sold onto processing or trading companies who then add their own specialised coating material to aid conductivity in the battery. This is most commonly a carbon coating of some form that is applied using a chemical vapour method.
- Production of uncoated spherical graphite is generally wasteful, with producers today achieving an average yield of 30-40% on initial flake concentrate input
- The only application for spherical graphite is as an anode material for lithium-ion batteries, with the majority of consumers being situated in either China, Japan or South Korea
- To become "battery-grade", spherical graphite must achieve a minimum of 99.95% TGC following purification
- Price is dependent on purity and particle shape / size
2.What capacity you expect? (kg/h)
3.What mesh or mm or micron(size) of the powder you want ?
4.What voltage you want ? For example,380V 50Hz, 3P ..
