摘　　要：盐酸法生产饲料级磷酸氢钙,在中和工艺的前期和中期利用碳酸钙中和,后期用石灰乳中和,可改善成品的结晶状况,从完全用石灰乳中和的粉末状变为流沙状,并减少非磷酸氢钙的钙含量,产品质量提高。Using calcium carbonate in the early and middle neutralization process, and using lime milk in the later neutralization process, the crystallization status of products is improved from powder to shifting sand in the feed grade dicalcium phosphate production by hydrochloric acid method, the calcium content without dicalcium phosphate is reduced, the product quality is increased.

关 键 词：饲料级磷酸氢钙 盐酸法 改善结晶方法 碳酸钙 石灰乳 产品质量
