Iron ore is an important industrial source, a kind of iron oxide ore, an economically available mineral aggregate containing iron element or iron compound, and there are many kinds of iron ore. Among them, iron-making products mainly include magnetite, siderite, hematite and so on. Iron exists in nature in the form of compounds, and natural iron ore can be gradually selected after crushing, grinding, magnetic separation, flotation and gravity separation. Therefore, iron ore is an important raw material in the field of steel production, iron ore with a general grade of less than 50% needs to be processed before smelting and utilization.
| Ingredient\Variety | Fe | O | H2O |
|---|---|---|---|
| Magnetite | 72.4% | 27.6% | 0 |
| Hematite | 70% | 30% | 0 |
| Limonite | 62% | 27% | 11% |
| Siderite | Main ingredient is FeCO3 | ||
| Fineness | 100-200 mesh |
|---|---|
| Model | Vertical mill or Raymond mill |
The material is crushed by the crusher to the fineness that can enter the mill(15mm-50mm).
The crushed small pieces of material are sent to the storage hopper through the elevator,and then sent to the grinding chamber of the mill evenly and quantitatively through the feeder for grinding.
Through classification, the coarse powder will return to main mill to grind again.
The powder that meets the fineness enters the dust collector through the pipeline with the air flow for separation and collection, and the collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged uniformly.
