Our factory dry production of calcium superphosphate with dilute acid has 37 years of history, the design capacity of the plant is 200 kt / a, the maximum output reached 250 kt / a, the use of layered phosphorite ore in central Yunnan as raw material. During the Ninth Five-Year Plan period, five technological innovations were completed, solving the difficulties in production. Are introduced as follows: 1 JDGF-type high-temperature flue gas boiling furnace in the phosphate rock drying application In the dry acid process, adding the mixer
