As the main raw material of iron and steel production, the iron ore finishes its iron removal work through stages of crushing, magnetic concentration, flotation and gravity concentration.
Iron ore crusher consists of coarse crushing, medium crushing and fine crushing. Among the iron ore crushing flow, the vibrator feeder, coarse crushing machine, medium crushing machine, screening machine, fine crushing machine and dry separation equipment are necessary equipment.
Low grade iron ores cannot be used as such for the production of iron and steel and need to be upgraded to reduce its gangue content and increase its Fe content. The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB).
Technological Process of iron ore crushing plant is: Iron ore----- transported by the dump truck ----- Vibrating feeder ----- Jaw crusher (Primary crusher) ----- Spring cone crusher (Secondary crusher) ----- Circular vibrating screen ----- finished product as the customer required
As the common crushing equipment, Iron jaw crusher has advantages of energy conservation, high efficiency, high production capacity and stable property, so it is the ideal choice of the iron ore coarse crushing.
In spite of its complex structure, Iron cone crusher has strength of high production capacity, fine crushing particle size, high abrasive resistance and values. The Iron cone crusher is widely used in the large-scale iron ore processing or crushing plant. In term of production efficiency and costs, the usage of cone crusher largely reduces the production costs.
The medium and fine crushed finished products with less than 12mm mineral particle size will be sent into ore groove for further crushing and drying. Therefore, to some extent, the proper crusher selection decides the iron ore processing plant efficiency and is important for companies whose main raw material is iron ore.
