Phosphorus is a necessary material for plant growth and plays an important role in seizing agricultural yields. China’s phosphate fertilizer production in the “Industrial Science Daqing”, “Agricultural Science Dazhai” thriving under the excellent situation, at present our province has a lot of phosphate fertilizer plant. Superphosphate is the province’s main varieties of production and use. The production method of superphosphate is: the phosphate rock crushed after sieving, adding 65% sulfuric acid, stirring mixing in the mixer, rock phosphate decomposition into a slurry, after the formation of chemical curing broken spread, and then shipped 7-10 days ripening warehouse heap, continue to respond
