When to Convey Mechanically and When to Convey Pneumatically?

While pneumatic conveying is by far the most hygienic conveying method for dry bulk powders, there are instances where mechanical conveying may be a better choice: processing facilities with nominal head room above equipment; a need for high speed transfer with minimal energy consumption; and transferring friable materials.

The main differentiator between mechanical and pneumatic is that mechanical conveying–including conveyor belts, slip stick, aero-mechanical, flexible screw, and bucket elevators – use a mechanical device that is in direct contact with transferred material. Pneumatic conveying uses gas (usually air) to transfer suspended material through tubes.
