1. It was calcined by calcium superphosphate, then cooled, crushed,
and sift to 180 after defluorinated and desulfurized treatment, and
had to be fed with calcium phosphate.
2.The sodium phosphate solution reacts with the right amount of
calcium chloride in the presence of excessive ammonia, and
precipitates insoluble calcium phosphate, which is filtered, washed
and dried, and obtained calcium phosphate products.
3.The saturated lime-milk solution and the thermal concentration
phosphoric acid reacted with the pH of 8.1.
Stored in a cool, ventilated warehouse. Stay away from fire and
heat. It should be stored separately from acid. The storage area
shall be equipped with suitable materials for shelter and leakage.
