摘　　要：国内饲料磷酸氢钙生产工艺的磷得率低 ,磷酸浓缩脱氟法的生产厂少。介绍了英国、意大利、希腊和俄罗斯采用湿法磷酸浓缩脱氟法生产饲料磷酸氢钙的工艺流程。The phosphor yield of domestic feed grade calcium monophosphate production processes is low,and there are a few production plants using the phosphoric acid concentration defluorination method.The process flow,main equipment specification and consumption figures of the feed grade calcium monophosphate production using wet phosphoric acid concentration defluorination method in the UK,Italy,Greece and Russia are introduced.
