Jet Mill,Fluid Energy Mill

Jet Mill or Fluid Energy Mill is a stationary mill that uses the energy contained in a fast-moving fluid to produce particle-size reduction by impact or abrasion of the particles. Two main types are in use— either the parallel type where the air is introduced to a circular grinding chamber or the opposed jet where two opposing fluid streams are impacted. The fluid used to carry the feed solids is normally compressed air, an inert gas, or steam. No media is used in fluid energy mills, the feed material and fluid providing the breakage forces.

The jet mill or Fluid Energy Mill system is composed of jet mill, cyclone separator, dust collector, draught fan and other parts. After filtering and drying, the compressed air is jetted into the milling chamber through nozzles. Materials are crushed by the continuous collision, friction, and shearing at the meeting point of multi-strand high-pressure air flow.
