| Monocalcium phosphate and phosphoric acid are then treated with alkali and lime. Pure white crystals of DCP settle at the bottom which are removed and washed several times with water. Thus, all impurities are carefully removed in two stages. Pure white crystals of DCP are filtered and dried, using a flubbed drier. The dried material is ground to desirable particle size and later tested in the quality control laboratory on various parameters. Only after quality certification from the quality control laboratory, the material is dispatched. |
