Yunnan Phosphate Fertilizer Industry Co., Ltd. to introduce production capacity of 4 0 0 kt / a TSP device, according to the market demand for calcium-rich products larger, while retaining the production of TSP products at the same time, the conversion of calcium-rich. The reasons for the selection of slurry process, no mixing method to produce calcium, the quality index of calcium-rich products, the production of calcium-rich indicators of the key components of the raw material wet-process phosphoric acid, phosphate rock parameters, raw material consumption and mineral acid Specific parameters of the calculation; reaction and drying of the key control parameters; production of calcium-rich product quality (w (P2 O5 effective) ~ 33%, w (P2 O5 water) ~ 30%〕. Invested less than 20,000 yuan, the smooth realization of calcium-rich production, improve the company’s economic efficiency
