The filter plate 323 of dismembyator 40 filters the two sides for being sized to lower dispersion chamber, when falling on the two sides under material, efficient cyclone 42
Work, material have respectively entered interior feed inlet 421 in outer feed inlet 422, and efficient cyclone 42 is equipped with inside and outside feed inlet, by object
Material is conducted batch-wise and spreads the work, when material respectively interior disperser and outer dispersion is intracavitary dispersed when, material passes through interior charging
Mouth 421 is discharged into, interior disperser high speed rotation, and the cavity where feed inlet 421 forms negative pressure cavity, and under high speed rotation, charging
Material inside mouth 421 collects in circinate toward both sides, since feed inlet 421 is up-narrow and down-wide, so that material is in negative pressure cavity through arranging
It is injected in after putting on dispersion plate 423, material is further dispersed by dispersion plate 423；
And the material being discharged into through outer feed inlet 422, dispersed under the efficient shearing force of distribution blade 424, because
This effectively breaks the agglomerating force between material while reducing and dispersing difficulty, guarantees the dispersion effect, to prevent material not
It is affected by the external environment, the material collection after ejection is on collection flitch 431, and after grinding stirring, collection flitch 431 is taken out
?；
To guarantee that material can make full use of, after the first grinding teeter chamber 3 is ground, air pump 321 is opened, gas
The tracheae 324 inside mill ball 325 is transmitted directly to by the cavity inside swing rod 322, which, will be residual by spraying except interior
It stays in 325 surface of mill ball to blow down with the material on milling zone inner wall, promote the feature of environmental protection being recycled while reducing material wave
Take.
