在 ３ 万吨／年过磷酸钙装置使用昆阳磷矿，比较了采用高温低浓、低温高浓以及添加活性剂三种工艺条件下的生产状况。生产表明，采用低温高浓并添加活性剂的工艺条件下，使用含 Ｐ２ Ｏ５ ２９．６３％ 的昆阳磷矿，磷矿 Ｐ２ Ｏ５ 转化率可达９７％ 左右，产品有效 Ｐ２ Ｏ５ 可达１８％ 左右，熟化３ 天后出厂，产品呈粉状，达到了优质、低耗的目的 In 30,000 tons / year of superphosphate installations using Kunyang phosphate rock, compared the use of high temperature and low concentration, high temperature and low concentration of active agent added under the conditions of three production conditions. Production shows that the use of low temperature and high concentration of active agent added process conditions, the use of P2 O5 29.63% of Kunyang phosphate rock, phosphorus ore P2 O5 conversion rate of about 97%, the product effective P2 O5 up to 18% About three days after curing factory, the product powder, reached the purpose of high quality, low consumption
