Jet mill

Jet mills use high-velocity compressed gas to drive particle-to-particle grinding. Fluidized bed jet mills can incorporate a dynamic classifier wheel to control product size. The diagrams below illustrate the relative positions of nozzles, classification and collection parts; order against the actual model and assembly drawing.

Jet mills (Hosokawa Alpine AFG fluidised-bed opposed-jet as the contrast anchor) grind by interparticle collision in gas jets and may include a dynamic classifier wheel. Motive energy is the gas stream—do not graft UPZ pin-disc/hammer hardware. Terminology/structure only; exhausted hard numbers stay off the table.

Part Identification and Technical Details

Terminology layer: nozzles/opposed-jet zone, classifier wheel, housing liners. Do not invent nozzle grades or hard numbers from the contrast table.

Materials for similarly named parts may differ by OEM, machine model and operating conditions. Confirm the machine model, drawing and measured dimensions before ordering or manufacture.

Jet / mechanical impact / classifier-mill terms (2026-11-01 · B2)

  • AFG jet mill: fluidised-bed opposed jets; interparticle collision; optional dynamic classifier.
  • UPZ fine impact mill: material hits mechanical tools; swappable pin disc / impact disc / hammers; pin mill = one rotating + one stationary disc.
  • ACM classifier mill: impact mill + built-in dynamic classifier; having air/classifier ≠ calling it a jet mill.
  • Boundary: OEM text also says jet mills are impact mills (broad sense); AFG vs ACM differ in energy source. Optional external cyclone classifier ≠ ACM internal classifier. Exhausted hard numbers stay off the parameter table.
