分析了目前过磷酸钙的生产过程，认为在过程后续阶段反应环境不利于硫酸和磷矿问进行质量交换。为搭建一个平台使硫酸和磷矿粉之间的反应渠道始终畅通，提出无熟化过磷酸钙工艺与二水物磷酸生产过程类似，通过提高矿粉细度和搅拌强度，降低硫酸浓度和反应温度，达到提高转化率的目的。过磷酸钙生产新工艺取消了化成、熟化工序，环保，节能，符合当前产业政策。

Through the analysis on production process ot SSP at present, it is concluded that the reaction environment is not favorable to the mass transfer between sulfuric acid and phosphate rock, which needs a platform to make the reaction between the sulfuric acid and phosphate rock unbloeked. It is put forward that the process of SSP production without formation is similar to the process of phosphoric acid production with dihydrate method, the conversion rate is increased by improving the fineness of phosphate rock and the stirring intensity, decreasing the sulfuric acid concentration and reaction temperature. The new production technology of SSP that cancels curing and formation is environment-friendly, energy saving, accord with the industrial policy at present.
