The invention relates to the technical field of
powder material
processing, and discloses an
inert gas protected micro-
powder impact mill
system which comprises a crushing and grading module, an
inert gas circulating module, a material closed conveying module and a
safety monitoring and regulating module, the crushing and grading module comprises an
impact mill and a worm gear grader, and a bottom
discharge port of the
impact mill is communicated with a top feed port of the worm gear grader through a sealing pipeline; the
inert gas circulation module comprises a gas
storage tank, an induced draft fan, a pulse type bag-type
dust collector and a return air cooler, a gas outlet of the gas
storage tank is in sealed connection with a gas inlet of the induced draft fan through a first communicating
pipe with a control valve, and a gas outlet of the induced draft fan is communicated with a gas inlet of the
impact mill through a second communicating
pipe. By constructing a complete
inert gas closed circulation loop and combining with a
safety monitoring regulation and control module of the integrated
control system, potential safety hazards caused when flammable, explosive and oxidizable materials are processed by an existing common
impact mill are effectively solved.
