21, No. two knockout drum 31 and of a knockout drum can be drawn into by the negative pressure of vacuum tube 100
In sack cleaner 41.
Under suction function, turbo separator 22 can rotate, and mica particles is drawn into by negative pressure
After in turbo separator 22, owing to having tapping channel 225 between blade 222, work as whirlpool
Wheel separator 22 forms centrifugal force after rotating, and makes the mica particles of larger particles escape into leaf
The outside of sheet 222 hence into a knockout drum 21 natural subsidence to the first discharging opening
In 23, form the separation of coarse fodder and collect.
Material after rough segmentation continues in No. two knockout drums 31, due to division board 34
Effect, make the material must be by the bottom of No. two knockout drums 31, major part material passes through
Second discharging opening 32 discharging, obtains finished product, and the less material of few part particle diameter is from No. two
It is inhaled into finished product collecting tank 31 top bottom knockout drum 31, continues into cloth bag and remove
Dedusting in dirt device 41, is provided with the 3rd discharging opening 43 bottom sack cleaner 41, the 3rd goes out
Material mouth 43 is provided with SAN GUAN air-valve 44, it is thus possible to complete the recovery of dust.
Material complete after above-mentioned steps feed intake, first separation, secondary separation and powder
The step that dirt is collected, is individually separated coarse fodder, finished product and dust and collects, separating rate
Hurry up, efficiency is high, and whole separation process is carried out in confined space, will not produce dust dirty
