Which crusher is best for manganese iron ore？

Iron ore is an important raw material for iron and steel production enterprises. Pure iron ore is gradually extracted from natural ore through procedures such as crushing, grinding, magnetic separation, flotation, and gravity separation. In theory, any ore containing iron or iron compounds can be called iron ore. The iron ore crusher is a kind of mechanical equipment that crushes raw iron ore step by step, from large raw iron ore (about 500mm) to millimeter-scale fine materials. The iron ore crushing process generally adopts the processes of feeding, primary crushing, secondary crushing, fine crushing, and screening. For the sake of economy, the finer the ore particle size, the iron ore the higher the proportion of being selected. So, which crushers are used for iron ore crushing?

1. Primary crusher-Jaw crusher and gyratory crusher

Jaw crushers are generally used for head crushing in iron ore production operations, and gyratory crushers are used for large-scale production units. Jaw crusher is the most traditional and most stable and reliable primary crushing equipment with the widest range of applications.

2. Secondary crusher - Fine jaw crusher and cone crusher

In the iron ore crushing production process, there are generally two types of secondary crushing: fine jaw crusher or cone crusher.

The fine jaw crusher is generally used in smaller iron ore beneficiation plants, the equipment value is low, the structure is simple, and the maintenance is simple and convenient. However, the minimum discharge port of the fine jaw crusher can only be adjusted to 25mm, so the crushing particle size is generally below 40mm.

The structure of the cone crusher is more complicated, and the equipment value is higher. However, its output is larger, the crushing particle size is finer, and the service life of wear-resistant parts is longer. Therefore, cone crushers are widely used in relatively large iron ore beneficiation plants. From the production efficiency and cost of iron ore, the use of cone crusher can effectively reduce the production cost. Because the cone crusher can provide a smaller product size, from the perspective of the overall process, it is the most economical production method to use laminated equipment to complete the main crushing task of iron ore.

3. Fine crushing machine - Vertical shaft impact crusher

The vertical shaft impact super fine crusher is a typical representative of the impact iron ore fine crusher. It adopts the crushing principle of strong impact, which increases the impact crushing energy of the material several times, so as to obtain a good fine crushing effect. The super fine crusher is the most widely used type of fine crusher, and it has a good crushing effect on various materials with high hardness, strong abrasiveness and high viscosity. The vertical shaft super fine crusher not only greatly reduces the cost of wear and tear, but also facilitates quick and easy repair and maintenance, and can easily meet the requirements of millimeter-level fine crushing operations. However, the input particle size of the vertical shaft super fine crusher is small, and generally materials below 50mm can enter the vertical shaft super fine crusher for fine crushing, which limits its application scope to a certain extent. If the crushing production line can be optimally configured, the vertical shaft super fine crusher can exert the most economical production efficiency.

4. Dry screen- Circular vibrating screen

The screening equipment generally adopts a circular vibrating screen to screen the materials completed by the secondary crushing. Generally, materials of 10mm or smaller can be screened for dry selection, materials of 10~40mm can be screened and then enter the fine crusher for fine crushing, and materials of 40mm or more can be returned to the secondary crusher for recycling and crushing. Of course, the particle size range of screening can be adjusted according to the actual situation, in order to achieve the most economical operation mode.

5. Iron ore crusher plant

The Iron Ore Crushing Plants are developed according to Baichy series iron ore crushing equipment's design idea, which expands the concept field of coarse crushing and fine crushing. Iron ore crusher is designed based on the conception of fully adapting various iron crushing condition. This series iron ore crusher plant really supply simpler, higher efficient lower cost machines.
