coal drying for medium and fine coal

The NDTdryingsystem uses molecular sieves (think little sponges) to wick water away from wetfine coalparticles and does not require crushing or additional finer sizing of the wetcoaltodryit. These molecular sieves are a form of nano-technology based particles, which are typically used for extracting moisture from airborne, aerosol and ...
