Question

Maximum size reduction in a fluid energy mill is achieved by

• A. Inter particle attrition
• B. Compression
• C. Cutting
• D. Impact

Hint:

Fluid energy mills rely on high-speed collisions between particles, not impact surfaces.

Answer 1

The Correct Option is A

In a fluid energy mill (e.g., jet mill), particles are accelerated and collide with each other.
This inter-particle attrition provides ultra-fine size reduction.
