Used 72,000 TPY Dicalcium Phosphate (DCP) Plant. Dicalcium phosphate is used as animal feed. The plant uses Phosphoric Acid and Calcium Oxide or Calcium Carbonate as raw materials. Phosphoric Acid and Calcium Carbonate are first reacted together with water, then fed to the updraft of the combustor where the reaction is finished and drying begins. The drying is coming from the reaction heat. No dryer is needed. The DCP plant also includes a granulation unit, which has 80,000 TPY capacity. It dries, sieves and mills DCP product to desired size.
