high pressure roller final grinding and dry separation technology for lean magnetite ore

Release Time:06/23/2020             

This technology adopts high pressure roller grinding system, which can partly replace (or completely replace) fine grinding and completely replace coarse grinding and fine grinding.After the material is extruded by the high pressure roller mill, the iron ore powder that reaches the target grain is sorted through the separation technology combining mechanical classification and wind classification, and then it is gradually raised to the target grade through magnetic separation at different particle sizes.Compared with the wet grinding and wet dressing technology, the power consumption of this technical system is reduced by about 30%, the water consumption is reduced by about 75%, the amount of tailings pulp is reduced by about 75%, and the steel consumption of the system can be greatly reduced.The operation cost of mineral treatment can be greatly reduced by greatly reducing water consumption and tailing pulp.
