The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated as follows.
Like Fig. 1-shown in Figure 3 is the structural representation of the intensity magnetic separator of the utility model embodiment.The permanent magnet vertical ring high gradient intensity magnetic separator of the utility model; Comprise drive unit 1, vertically (promptly axially being horizontally disposed with) and separation ring 2 that is driven by said drive unit 1 and the permanent magnetic system 3 that acts on 2 times rings of said separation ring section portion be installed, said permanent magnetic system 3 encircles for 2 times around the section portion for being located in said separation ring.
Fig. 4 is the structural representation of the permanent magnetic system of the utility model embodiment.As shown in Figure 4, said permanent magnetic system 3 comprises two groups of permanent magnetism magnetic pole groups, and the magnetizing direction of said two groups of permanent magnetism magnetic pole groups is vertical direction and polarity is identical.
