Science Behind Technology

Desmet Ballestra proposes its in house Bi Fluid Drum Granulation (BFDG) technology for the following applications:

Ammonium nitrate and calcium ammonium nitrate fattening

Ammonium nitrate or Calcium ammonium nitrate prills from the existing prilling tower are used as seed material and sprayed with ammonium nitrate or calcium ammonium nitrate melt in the Bi Fluid Drum Granulator (BFDG). It is one-through without recycle loop. Fattened prills are screened on a finishing screen and oversized particles are molten and recycled to the ammonium nitrate.
