Principle of Fluid Energy Mill
Fluid Energy Mill Operates on the principle of particle size reduction by collision.
High-velocity air or gas jets are used to create turbulent conditions, leading to size reduction through particle collision.
Construction
Grinding Chamber: Circular or oval chamber with no moving parts.
Nozzles: High-pressure air or gas jets.
Feed Mechanism: Hopper for material input.
Classifier: Separates fine particles from coarse particles.
Discharge Mechanism: Outlet for processed material.
Working
Material is introduced into the grinding chamber.
High-velocity air or gas jets create a turbulent flow.
Particles collide at high speeds, leading to size reduction.
Fine particles are separated by the classifier and discharged.
Uses
Fine and ultra-fine grinding of heat-sensitive and friable materials.
Common in pharmaceutical, cosmetic, and chemical industries.
Merits
Produces very fine particles.
No moving parts, leading to minimal wear.
Suitable for heat-sensitive materials.
Demerits
High energy consumption.
Limited to small-scale production.
Requires careful control of operating parameters.
