### DENSE-PHASE PNEUMATIC TRANSPORT OF COHESIONLESS

particles are conveyed in a dilute phase above a stationary layer. Large peaks in the pressure drop data (approximately 1 to 2 kPa) correspond to increases in the dilute-phase solids concentration. At the lower superficial air velocities (below 5 m/sec) , the solids flow pattern changes to dense-phase flow.

### Introduction to Pneumatic Conveying of Solids

What is pneumatic conveying? Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.

### Handbook of Pneumatic Conveying Engineering

dense phase, as illustrated in Chapter 8, low pressure conveying is generally lim-ited to dilute phase conveying, unless the conveying distance is very short, as will be seen from Figures 11.1 to 11.4. In dilute phase, however, almost any material can be pneumatically conveyed, regardless of the size, shape and density of the particles.
