摘要：介绍了我国硫酸法生产饲料级磷酸氢钙的工艺，指出了其存在的问题，并提出了一种新的工艺。新工艺的实验结果表明，产品平均粒径达到60-70μm，湿含量下降到18．7％，中和后的水能满足化灰所需用量。新工艺提高了产品的质量，降低了能耗，也促进了水的循环利用。
The conventional process to produce feed- grade calcium hydrogen phosphate with sulfuric acid method in China is introduced. A series of problems of the conventional process are pointed out. To solve these problems, a new process is proposed. The results indicate that the average particle size of product produced by new process is about 60 - 70 μm and the moisture content decreases to 18.7%. The water after neutralization can meet the need of lime slaking. This new process improves product quality, reduces power consumption and realizes the cyclic utilization of water.
