    and unloaded on the port. It is usually used for loading and unloading process of feed on the port as designed,
    but it can be applied to other works that the powder is put to the hopper. (Patent registered 10-1542351)
  • Reduction efficiency
    More than 95% of dust that occurs on loading and unloading process of feed can be reduced.
    (The efficiency is more than 95% even the wind blowing 3m/s.)
    Scattered dust is filtered by multi cyclone and ULTRANANO filter in the dust collecting facility
    and collected by the screw conveyor.
