The Fluidized-bed jet mill is actually such a device as using the
high-speed air flow to perform the dry-type superfine pulverizing.
Driven by compressed air, raw material is accelerated to the
crossing of four nozzles to be impacted and grinded into powder,
then, the grinded powder will be brought by upward flowing air to
the grading zone, influenced by centrifugal force and air flow,
powder up to grade will be separated and collected; other powder
swirls back to milling chamber for further milling processing.
