Inert Gas Protected Air Mill

Working Principle

The inert gas protected air classifier mill uses inert gas as the crushing medium. After inert gas is filled into the system to isolate the material from air completely, the material is sent into the crushing chamber of the main crushing unit via a conveying device. The compressed high-speed inert gas stream directs the material into the nozzle intersection, causing it to repeatedly impact and collide, achieving the crushing effect. The crushed particles enter the classifier area of the impeller, where they are separated by the centrifugal force of the classifier wheel and the action of the fan. The qualified fine powder is then collected in the dust collector, while the coarse powder returns to the crushing chamber for further crushing. The inert gas is recycled back to the compressor for reuse, ensuring the entire system operates under a fully sealed condition.

Features

Specifically designed for operations requiring inert gas protection during grinding, suitable for ultra-fine grinding of flammable and oxidizable materials. Oxygen content can be controlled to100 pieces

1. High versatility. Suitable for crushing materials that are flammable, explosive, easily oxidizable, and require isolation from oxygen.

2. Recycles inert gases, low consumption.

3. The equipment experiences minimal wear, as the materials are crushed by mutual impact and collision, reducing wear on the equipment cavity.

4. Wide particle size range available, with the option to choose from d98=1-20um.

5. Equipped with a PLC controller, it achieves full automatic control and is easy to operate.

Application Fields

Widely used in the spreading, sieving, and shaping of materials such as cobalt powder, titanium compounds, nitrides, boron carbide, magnetic materials, nickel powder, tantalum powder, and sun powder, as well as related materials.
