| Abstract: | Because of the shortage of high grade phosphate rock, the ammonium phosphate production with low and medium grade phosphate rock by two-step neutralization and slurry concentrated process has been paid more and more attention by phosphate compound fertilizer enterprise. Taking the 200 kt/a DAP plant with the low and medium grade phosphate rock as the raw material as an example, process design essentials, control parameters and the calculation of thickening equipment selection are introduced to provide the reference for process design of Similar plant. |
