At the third circle hammer knife of grating disk, in the process with the continuous distillation of dry ice, material is chilled to ideal temperature.Fall on powder
Material at the third circle hammer knife of broken disk is hammered knife into shape by the second circle hammer knife, first lap, finally and is crushed under the effect of centrifugation
Sawtooth on gear ring collides and under the upward cold wind effect of the evaporation ends of heat pump, constantly pulverized simultaneously as air-flow rises.On
It rises after air-flow reaches convex cover and changes direction, qualified little particle is graded turbine suction under the action of stage turbine suction
Enter；Ineligible bulky grain and the material of screw-feeder push together, fall at the third circle hammer knife of grating disk and continue
It is pulverized.The dust particles for being graded the sucking of turbine suction are further graded by being classified sieve plate, can not pass through classifying screen
The larger particles of plate continue to crush by what feed back pipe flowed back to crushing bin, and the fine particle by being classified sieve plate enters next
Process (cyclone separation system).
Above-mentioned specific embodiment is the preferred embodiment of the utility model, can not be defined to the utility model,
Other any changes made without departing from the technical solution of the utility model or other equivalent substitute modes, are included in
Within the protection scope of the utility model.
