In practical processing process, the coarse ore is first crushed by jaw crusher until to a suitable particle. And then, the ore is conveyed by hoister and feeder into the ball mill for further crushing. After grinding of ball mill, the qualified ore will be classified. Because of different specific gravity, the solid particle has different settling velocity in the liquid, and it is washed and classified. And then, the ore put into the magnetic separator. Ore varies from specific susceptibility, and it gets different magnetic force and gravity. This process contributes to separating the magnetic material and non-magnetic material. After that, the material is conveyed into the flotation cell. According to their different physical and chemical properties, the objective mineral and other minerals are separated by flotation reagents. When the objective minerals are achieved, they contain much moisture. The dry iron concentrate is achieved by the thickening and drying.
At present, the domestic magnetite ore beneficiation processing line is mainly used to beneficiate the low grade “Anshan style” magnetite ore. In domestic, most concentration plant adopts the stage grinding and multiple stage grinding. When the ore is coarse-disseminated, the first stage grinding is adopted. And when the ore is fine-disseminated, another stage grinding is adopted. Xinhai has been working on providing advanced and practical process, high-efficient and energy-saving equipment, high-qualified and considerate service. Xinhai mining machinery is a modern mining company that tries his best to bring the maximum profits to you.
