Specific embodiment
With reference to Fig. 1 to Fig. 3, a kind of 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 phases 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 phases collect separation dress
Put 3 underfaces for being located at negative-pressure air fan collector 2；RO phases collect 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；Adjusting Pressure Actuated Device 7 controls grinding roller 5 to rotate；Vertical mill machine
The locating shaft set 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 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 pipe is located at vertical mill machine
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 the interior of vertical mill body 1
Portion.
The present embodiment is preferred, and the blanking port 402 of materail tube 4 is located at RO phases and collects 3 lower section of separator；Blanking port 402
Lower section is the center of mill 6.6 edges can make process of the increase fine powder on mill 6 from center to mill, so as to reach
The purpose being fully ground.
The present embodiment is preferred, and mill 6 is the conical surface with 5 joint face of grinding roller, and cone angle is 160 °~175 °.At 160 °~175 ° angles
The grinding that fine powder under the influence of centrifugal force preferably falls blanking port 402 is allow adequately to be ground in the range of degree.
The present embodiment is preferred, adjusts Pressure Actuated Device 7 and includes pressue device, speed reducer and motor；Pressue device is set
It is placed in the junction between 1 inner wall of grinding roller 5 and vertical mill body；Speed reducer connects control grinding roller 5 with speed reducer and rotates.Pass through tune

Feed inlet 401 and tube body are fallen by blanking port 402 in 6 center of mill again.With the rotation of mill 6, slag fine powder is in centrifugal force
Under the action of, it is taken up to 6 edge of mill by vane high-speed flow, bulky grain falls directly on mill 6 grinding again.
When in subdivision under the collective effect of annular airflow and negative-pressure air fan collector 2, by the subdivision of milled directly from going out
Material mouth 201 recycles, and RO phases fine powder can not be ground, because hardness itself is big when it is ground to the range of 50 ~ 55um
When, it is picked up under negative-pressure air fan collector 2 and annular airflow collective effect, but since quality itself is larger, it is simple by negative
It can not be sucked out from discharge port 201 for the suction of pressure fan collector 2, and RO phase fine powders drop into RO phases and collect in separator 3,
Then it is collected by RO phases and is discharged in the delivery line 301 of 3 lower part of separator, so as to achieve the purpose that remove RO phases.
Slag frame phase Vickers hardness scale：
Slag is screened, measures and sieves upper, RO phases under sieve content and the 153% and 71% of raw steel slag RO phase contents, RO under sieve on sieve
The ratio of phase content is 2.2, therefore RO phase selectivity is enriched in coarse powder during steel slag grinding.RO phase hardness is big levigate
Degree it is small be enriched in coarse powder, so gravity screening effect is good.
