| Abstract: |
| Aiming at the problem of low classification efficiency caused by narrow ore feeding in secondary classification of Qidashan Iron Concentrator, the influence of structure parameters of hydrocyclone on classification effect was studied deeply by numerical simulation method on the basis of field hydrocyclone system examination. The results show that the feed body structure is changed to spiral feed body, the diameter of bottom flow port is changed from 152 mm to 110 mm, the diameter of overflow port remains unchanged at 200 mm, the compound cone Angle is 12° for the middle cone and 20° for the small cone, and the classification efficiency of the new structure is increased by 7.37 percentage points compared with that of the field cyclone. The new structure of hydrocyclone can effectively improve the low efficiency of secondary classification in Qidashan Iron Concentrator, and provide reference and basis for the structure optimization of hydrocyclone in the same type of mine. |
