Selecting equipment to transport particles around 200-mesh size (~74 μm): which conveying method is most suitable?

Introduction / Context:
At ~74 μm, particles behave like dust, requiring enclosed handling to prevent losses and environmental exposure.

Concept / Approach:
Pneumatic conveying excels for fines, providing sealed transport and good control of bends and elevation changes. Bucket elevators and belts are more suitable for granules; screws can handle fines but may leak dust and degrade flow consistency.

Final Answer:
Pneumatic conveyor
