In recent years, domestic mineral processing equipment for industrial applications better, the main process hematite three, the most common is a continuous grinding, thickness sorting, re-election - magnetic separation - anionic reverse flotation process, its application and process characteristics Yes:
1. A stage grinding process is adopted. Since the process takes stage grinding, the stage selection process makes the process more economical.
2. The selection is highly targeted. The dissociation of minerals during the grinding process is random. This process makes the mineral particles with different grinding grain sizes have relay conditions, which is one of the important foundations for the strong subdivision process.
3. A narrow-level selection is achieved. In the mineral selection process, the degree of mineral selectivity is related to the mineral's own characteristics, and is also related to the specific surface area of ​​the mineral particles. This effect is more prominent in the flotation process.
4, the fine-grained grade selection effect has been unprecedentedly advanced. Stage grinding, coarse subdivision selection, re-election-magnetic separation-anion reverse flotation process application, stage grinding selection process of hematite beneficiation application The fine-grained process is magnetic separation-acid positive flotation process, beneficiation efficiency Very low, affecting the improvement of technical indicators of the stage grinding process.
Boiler Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler.
It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its enthalpy.
Bare tube type steam superheater coils, plate super heaters are commonly used.
