Blade 222, middle ring 23, lower graded blade 24, lower ring 25, fixed frame 26；High pressure work nozzle 3, mixing chamber 4, pulverizing chamber 5, object
Expect import 6, recurrent canal 7, tedge 8, auxiliary air entrance 9, products export 10.
Specific embodiment
With reference to the accompanying drawing, by the following detailed description, to be more clearly understood that the above and other of the invention
Objects, features and advantages.Hereinafter, the preferred embodiment of the invention will be described in detail with reference to the accompanying drawings.
Such as figure, the utility model is in a kind of Counter-impact flow pulverizer for improving grinding efficiency, the powder including organism bottom
Broken room 5, body upper fluidising chamber；
The utility model thes improvement is that the pulverizing chamber 5 is equipped with tedge 8, which is connected to the stream
Change room, and extends upwardly in the middle part of fluidising chamber；In the fluidising chamber, the top of tedge 8 is equipped with grading rotor 2, the classification
2 top of rotor is connected to transmission device 1；The transmission device 1 includes driving motor, and is moved by what shaft coupling was connected to motor
