Gypsum Fertilizer Plant Suppliers in Asia and Middle East

The Mineral Gypsum or Phospho Gypsum is Screened for lumps. The lumps are crushed fine. The powder is mixed with the binder and hardener and transferred to the granulator. In the granulation drum a very fine spray of water is done on rolling material at its angle of repose. Some coating of powder over the small nuclei / particles takes place.
