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. High-velocity impacts can break down granules into unwanted
Fans, blowers, or compressors that provide the kinetic energy. Particles are fully suspended in the air stream
Engineers must balance several variables to prevent system failure:
Systems are generally categorized into two main regimes based on the concentration of solids relative to air:
The relationship between air velocity and material behavior is captured in the . As air velocity decreases, the pressure drop initially drops (similar to clean air flow) until it reaches a critical point where particles begin to settle. Below this "saltation velocity," the flow transitions from a homogeneous mixture to a more erratic, dense-phase movement. 2. Modes of Transport
