        Calcium Chloride Production Line
        1. Food grade calcium chloride process:

        30% diluted hydrochloric acid reacts with limestone to prepare liquid calcium chloride.After filtration and seperation,filtrate is neutralized with lime milk.
        Under certain PH limit,impurities in calcium chloride solution like Mg 2+,Al3+
        ,Fe3+ form precipitates which hardly dissolve in the solution.After the filtration,filtrate is fed into the fluid bed dryer for drying and pelleting,and finally get the food-grade calcium chloride product. Exhaust air from the flud bed dryer is vented after cleaning.
        Food grade calcium chloride Index

        No.
