Embodiment Construction
[0018] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.
[0019] Such as figure 1 Shown, magnetite dry selection of the present invention throws tailings pre-selection process flow as follows:
[0020] (1) The magnetite ore is sent to the coarse crusher 2 by the mine car 1 for crushing, and the coarse crusher 2 discharges the material through the coarse crushing belt conveyor into a section of dry magnetic pulley 3, and separates a section of concentrate product and a section of waste rock.
[0021] (2) A section of concentrate product enters the middle crusher 5 through the middle crusher ore bin 4 from the first section of the concentrate belt machine, and a section of waste rock enters the first section of waste rock bin 6 through the third belt conveyor.
[0022] (3) The discharge of the intermediate crusher 5 enters the second-stage dry magnetic pulley 7 through the intermediate cru...
