Iron ore crushing Characteristic

Iron ore is an important raw material for steel producers. Natural ore (iron ore) is gradually selected for iron after crushing, grinding, magnetic separation, flotation, and re-election. Iron ore is a mineral aggregate that contains iron elemental or iron compounds that can be economically utilized.

Iron ore crushing Process

In the iron ore crushing sub-selection, the proportion of crushing equipment and grinding equipment investment, consumables loss and electric energy consumption is large, and the beneficiation process design must be efficient, concise and economical. In the consideration of the design of the crushing section process, the principle of “breaking more and less grinding” is adopted. Mainly adopts: the process of multi-stage crushing of jaw crusher + coarse crusher crusher + fine crusher crusher + high pressure roller mill.

The first paragraph: iron ore crushing section

When the traditional crushing equipment is crushed, the iron crushing material can only be crushed to 0-12mm. The Dahongli machine can reduce the iron ore raw material to 0-5mm by using an optimized design. The cost and time of subsequent grinding.

Second paragraph: grinding section

The 0-5mm iron ore material crushed by the crushing section enters the ball mill for re-grinding, and has reached the requirements of the subsequent process materials. The ball mill usually works with the classifier to form a grinding and grading unit. The ball mill grinds the material to be treated, and the classifier divides the ground product into qualified materials and unqualified materials. Unqualified products are returned to the ball mill for regrind to improve the grinding process. The grinding operation entered by the classifier and the graded return sand constitutes a grinding closed section. The grading work can be pre-grading, checking grading, controlling grading, or both. The grinding machine can be used in the form of rod grinding and ball milling in the grinding process.

Third paragraph: magnetic segment

For the different metal components of iron ore, the beneficiation process can be carried out in combination with multiple beneficiation processes. Use a wide range of gradient magnetic separation, strong magnetic separation, flotation, and the like.

Fourth paragraph: drying section

The magnetic powder after the magnetic separation is sent to the dryer, and the drying process mainly removes the water content of the selected iron powder in the beneficiation process to obtain high-quality iron fine powder.
