Magnetite ore beneficiation process

Generally it adopts two-process crushing, one-process grinding, three-stage low intensity magnetic separation process. That is to say, rough crushing, fine crushing, screening, fine grinding, classifying and three-stage low intensity magnetic separation process. The detailed process is as follows: the raw material first screened big granules away by bar grizzly, is send to the rough crusher by the vibrating feeder, then to the fine crusher. After that, the raw material comes to screen, at this process, the material on the screen(big granules) will go back to the fine crusher for a second crushing. And the material below the screen is acceptable product which can be transferred to the fine ore bin. Under the bin there should be a feeder, the fine ore is send to the ball mill by belt conveyor. And further, the material goes to the spiral classifier, also the big granules are send back to the mill for a second grinding. The material in the spiral classifier overflows and goes to three-stage low intensity magnetic separation process.
