Specific embodiment
In conjunction with Fig. 1 to Fig. 3, a kind of steel slag fine powder mill vertical mill for removing RO phase mineral is present embodiments provided, including vertical
Grinder body 1, negative-pressure air fan collector 2, RO phase collect separator 3, materail tube 4, grinding roller 5, mill 6, adjust pressure actuation
Device 7；The top of vertical mill body 1 is equipped with discharge port 201；Negative-pressure air fan collector 2 is located at the top in vertical mill body 1；
Discharge port 201 is located at 2 top of negative-pressure air fan collector；Materail tube 4 is located on 1 side wall of vertical mill body；RO phase collects separation dress
Set 3 underfaces for being located at negative-pressure air fan collector 2；RO phase collects separator 3 equipped with delivery line 301, and delivery line 301 is from vertical
It is pierced by and is reached outside vertical mill body 1 on the wall of grinder body 1；It adjusts Pressure Actuated Device 7 and controls the rotation of grinding roller 5；Vertical mill machine
The locating shaft being arranged on 1 inner wall of body, grinding roller 5 are fixedly connected with locating shaft；Grinding roller 5 is contacted with mill 6, is driven and is ground by grinding roller 5
Disk 6 rotates.
The present embodiment is preferred, and materail tube 4 includes feed inlet 401, tube body and blanking port 402；Feed inlet 401 is located at vertical mill
The outside of body 1；The inner and outer wall of tube body and vertical mill body 1 is fixedly linked；Blanking port 402 is located at vertical mill body 1
It is internal.
The present embodiment is preferred, and the blanking port 402 of materail tube 4 is located at RO phase and collects 3 lower section of separator；Blanking port 402
Lower section is the center of mill 6.6 edges can make to increase process of the fine powder on mill 6 from center to mill, to reach
The purpose being fully ground.
The present embodiment is preferred, and mill 6 and 5 joint face of grinding roller are the conical surface, and cone angle is 160 °~175 °.At 160 °~175 ° angles
