Lithium Manganese Oxide Powder Grinding Machine Spiral Jet Mill

Lithium Manganese Oxide Powder Grinding Machine Spiral Jet Mill

Spiral Jet Mill Features

Widely used in chemical, single crystal ternary materials, small particles of lithium cobalt oxide, lithium hydroxide, lithium carbonate and other industries.

1.Available particle size D50:1.5-25μm；

2.Built-in calssifying wheel for high precision；

3.Constant temperature(20°C) or low temperature, medium-free grinding, especially suitable for materials of heat sensitive, low melting point, sugary, volatile nature；

4.Key parts like inner liner, classifying wheel and nozzle are made of ceramic such as aluminum oxide, zirconium oxide or silicon carbide, ensuring non-contact with metal throughout the grinding for high purity of the final product；

5.Grinding is in closed system, low dust and noise, clean and environmentally friendly production process；

6.PLC control system, easy operation.

Spiral Jet Mill Working Principle

Jet Mill works with cyclone separator, dust collector and suction fan to form a complete grinding system. 

Compressed air flow after filtration and drying would go into milling chamber from nozzles, and meet in the center area, where material would be impacted and ground and sheared. 

Milled powder would go up to the classifying chamber by the air flow from suction fan. The high-speed rotation of classifier wheel would create a strong centrifugal force to separate coarse powder and fine powder. 

Qualified fine powder would 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.

Application of Lithium Manganate

Lithium manganate has the advantages of rich resources, low cost, no pollution, good safety, and good rate performance. It is an ideal power battery cathode material, but its poor cycle performance and electrochemical stability greatly limit its industrialization . Lithium manganate mainly includes spinel type lithium manganate and layered structure lithium manganate. Among them, spinel type lithium manganate has a stable structure and is easy to realize industrial production.
