Iron ore beneficiation equipment and technology

In terms of iron ore beneficiation process, it can be divided into the dry and wet selected section. A lot of iron ore beneficiation unit, usually separate dry section from wet selected section, there are some units will be Section of Dry and wet-election set together. Regardless of the manner in which the goal is to achieve maximum efficiency.
1. Iron ore crushing equipment
Jaw crusher is the main primary crushing equipment of iron ore, and the cone crusher as the secondary crushing machinery. Very different physical characteristics of the iron ore, mainly the hardness of the difference is very obvious. Regardless of what types of low-grade magnetite, we all need iron ore crushing equipment, crushing the low grade iron ore to a certain particle size range, and then use dry separation equipment for the primary mineral dressing. In general, the smaller the granularity of low grade iron ore crushing, the higher beneficiation efficiency of the dry sorter.
2. Iron ore dry separation equipment
Iron ore dry separation equipment is generally based on the strength of the magnetic field, which can be divided into magnetic and weak magnetic dry sorter. The magnetic dry sorter run tail can be reduced, but not to improve the quality. Weak magnetic dry sorter can effectively improve the taste, but it will increase the amount of run tail. Therefore, the use of the dry sorter need analysis and comparison. Different iron ore mines , choose different types of dry separation equipment. Of course, under conditions permitting, modular dry election process is feasible, the first magnetic dry sorter for waste removal, and then the weak magnetic dry sorter to effectively improve the quality.
3. Iron ore grinding equipment
Iron ore grinding equipment is ball mill. In the iron ore grinding process, there are two grinding design and single-stage grinding design. Two or a single segment depends on the characteristics of iron ore. The lower hardness of the smaller particle size of iron ore, you can use the design principles of the single-stage ball mill. Conversely, high hardness, particle size larger iron ore, adopt two milling process design.
4. Iron ore wet separation equipment:
Iron ore grade after the dry sorter enrichment, has been raised to about 16%. After ball mill grinding operation, using iron ore wet separation equipment further enhance the enrichment of iron, the magnetic powder to remove impurities. As part of the iron ore particle size after the mill is still not meet the requirements, we also need to use high frequency screen filter, materials that not meet the size requirements, branch to the ball mill for repeat processing. Iron ore wet sorting equipment can adopt one, two, three level configuration principle, to obtain the maximum degree of taste enhance and reduce run tail losses
