Rotary valves, screw feeders, or pressure vessels that introduce solids into the moving air stream without letting air escape backward.
Cyclones or bag filters that decouple the material from the air at the destination. 4. Practical Challenges
Abrasive solids can "sandblast" through pipe elbows if velocities are not strictly controlled.
High velocity, low pressure, and low solids-to-air ratio. Particles are fully suspended in the air stream. It is versatile and easy to operate but requires high energy and can cause significant material degradation or pipe wear due to high speeds.
Systems are generally categorized into two main regimes based on the concentration of solids relative to air:
Fans, blowers, or compressors that provide the kinetic energy.
High-velocity impacts can break down granules into unwanted fines.
