Hematite Ore Crusher

Main Application of Hematite Ore
 
 I． Magnetic Materials
Hematite ore not only can be used to make soft magnetic material but also to make hard magnetic material.

（2）Soft magnetic material
Soft magnetic material, also called industrial pure iron. It has the feature of super paramagnetic, low coercivity, low Curie temperature, high magnetic susceptibility and giant magnetoresistance. Nowadays, the soft magnetic material is widely applied in industrial automation device, electronic instruments, Communication Equipments, electric power, computer.

3. Hard magnetic material
  Hard magnetic material, also called permanent magnet, is used more and more in the recent year. Its raw material, iron oxide is made from hematite ore. The hematite ore shall meet the following requirements:
Grade of Iron: TFe>68, 6%; silicon content: High-grade magnetic materials SiO2<0.3%; Mid-grade magnetic material SiO2 0.3～0 .5%.

4.  Raw Material of Paint
Hematite ore is a type of good inorganic rust resisting pigment. After the purification and grinding, qualified ore can be used as the raw material of paint. In this way, the value of hematite ore is increased greatly.

5．Other application
Hematite ore concentrate can be used to make welding electrode; to make iron powder by using fluidized reduction method, to make sponge iron; or to make non-equilibrium materials and iron powder by adopting rapid cooling method, the iron powder can be used for waste water treatment and food fresh keeping. The powder can also be used for making chemical paint and storage battery. The high-grade sponge iron is the raw material of Special Steel.

If it is needed to process the soluble-salt material in the ore and primary slurry, it is better to adopt single stage crushing process including preliminary classification and inspection classification. Preliminary classification is mainly used to remove the particle size qualified stone in the material to improve the crushing capacity, or to eliminate the ore slurry. This process usually uses the mechanical classifier. In order to avoid the excessive crushing, the upper limit of the spiral classifier’s feeding size shall be less than 7mm.

Hematite ore crusher, such as jaw crusher, impact crusher, cone crusher manufactured by Zhengzhou Unique Industrial Equipment Co., Ltd is widely used in the hematite ore crushing plant.
