Vertical Mill feed back of the present invention closed cycle is selected the iron system compared with prior art, has the following advantages:
1. the iron system is selected in Vertical Mill feed back of the present invention closed cycle, by raw material closed cycle transmission, arranges in transmitting procedure and how to magnet arrangement, to be selected iron, has improved the deironing rate, and the deironing rate brings up to 98% from original 50%-60%.
The accompanying drawing explanation
The structural representation of iron system is selected in the Vertical Mill feed back closed cycle that Fig. 1 is one embodiment of the present invention.
The specific embodiment
Explanation that the present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Fig. 1 has schematically shown according to the Vertical Mill feed back closed cycle of one embodiment of the present invention and has selected the iron system.
As shown in Figure 1, the iron system is selected in the Vertical Mill feed back closed cycle of the circulation deferrization for the raw material process of lapping of the present invention, comprising: vertical mill 1, for the first transport tape 2 of charging transmission, be located at the second transport tape 3, lifting device 4 and the conveying worm 5 of vertical mill 1 discharging opening.
The input section of the first transport tape 2 is connected with batch bin, and output is connected with conveying worm 5, batch bin discharging to the first transport tape 2; Transfer to conveying worm 5 by the first transport tape 2, by conveying worm 5, material is inputted to the charging aperture of vertical mill 1; Deliver to vertical mill 1 and grind, the material after grinding is exported from discharging opening, to the second transport tape 3; Lifting device 4 is transported to the first transport tape 2 again by the material of the second transport tape 3 outputs.Form with closed-loop path with this, constantly material is ground, to qualified, by device for suction material 9 sucking-offs that are communicated with vertical mill 1 inner chamber.
As shown in the figure, the output of the first transport tape 2 is provided with directly over the first deironing apparatus 201, the second transport tapes 3 output that is provided with the second deironing apparatus 301, the second transport tapes 3 and is provided with the 3rd deironing apparatus 302; Lifting device 4 and the first transport tape 2 junctions are provided with the 4th deironing apparatus 401.The second deironing apparatus 301 is the electromagnetism deironing, and the first deironing apparatus 201, the 3rd deironing apparatus 302 and the 4th deironing apparatus 401 are dry type permanent magnetic separator.
Dry type permanent magnetic separator by the 3rd deironing apparatus 302 is selected the powder after iron to enter filler bin 6, and scum enters the first scum storehouse 7; Lifting device 4 is promoted to the first transport tape 2 by the powder in filler bin 6.Dry type permanent magnetic separator by the 4th deironing apparatus 401 is selected the powder after iron to fall into the first transport tape 2, and scum enters the second scum storehouse 8.
