Inert Atmosphere Protection

Classifying System

Closed loop air classifier is an ultra-fine classifying system in inert gas(nitrogen gas,argon gas,carbon dioxide)atmosphere,specially designed for flammable and explosive,easy oxidization material.The system is upgraded from the ordinary air classifier system,mainly composed by closed feeding system,air classifier system,gas circulation system and control system.

System Features:

  • Inert gas can be changed according to materials.
  • Purity of inert gas can be precisely controlled according to the requirement of product.
  • Closed loop system, minimum inert gas consumption.
  • Suitable for heat sensitive and low melting point material, thanks to temperature decreasing cased by gas expansion.
  • Air sealing system brings accurate classifying.
  • De-agglomeration for agglomeration ultra-fine powder.
  • Accurate classifying thanks to high efficiency classifying rotor.
  • Particle size adjustable between 2-74μm. Classifying flow distribution technology brings high classifying performance and narrow particle size distribution.
  • The whole system is running under negative pressure. Dust on filter bag is cleaned by automatic impulse. Filtration rate can reach 99.99%.
  • Back up filter behind dust collector to prevent dust entering air compressor.
  • Automatic PLC control system for the plant. Simple operation.
