METHOD OF GRANULATED SUPERPHOSPHATE PRODUCING |
| 摘要 |
FIELD: fertilizers. SUBSTANCE: invention relates to processing dolomitized phosphate raw containing 26-28% P<SB>2</SB>O<SB>5</SB> and 2.5-3% MgO (as measured for granulated superphosphate). After preliminary classification stage the large raw fraction at ratio solid : liquid = (1.04-1.85):1 is treated with sulfuric acid. For neutralization small fraction of phosphate raw (particle size is 0.02-0.1 mm) is fed. Ready product has at least 15% P<SB>2</SB>O<SB>5</SB> at 1.5-1.7% bound P<SB>2</SB>O<SB>5</SB>. EFFECT: intensified process, decreased energy consumption. 2 tblm
