How do Granule Blowers distribute granules?

• A. Granules are metered from a hopper into a high-velocity air stream (75 to 150 mph) that blows the granules through a nozzle or spreader.
• B. They are pumped through a narrow jet of liquid to create a mist.
• C. They rely on a rotating cylinder to fling granules outward.
• D. They do not require any air movement to distribute granules.

Answer: (A)

Air-assisted distribution is the idea here. Granules are metered from a hopper into a high-velocity airstream, typically 75 to 150 mph, and the moving air carries the granules out through a nozzle or spreader. This setup lets dry granules travel through the air to reach target areas and provides control over how much product is released and how far it travels, giving even coverage over large or uneven surfaces.

This approach differs from spraying methods that create a liquid mist, from devices that fling granules outward with a rotating cylinder (centrifugal spreaders), or from systems that dispense without relying on air movement.
