Dense phase pneumatic conveying involves the transfer of powders, granules, and other dry bulk materials through an enclosed pipeline. In dense phase conveying, particles are not suspended in the conveying air and are transported at high pressure and low velocity. This results in a more gentle delivery process for the products being conveyed.

More### 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.

These constitute the most widely used of pneumatic conveying systems. Dense-Phase. There is no universally agreed-upon demarcation of when a dilute-phase (material-into-air-to-stream) system becomes a semi-dense phase or dense-phase plug-flow system. For US Systems, a dense-phase system is a system that requires a rated pressure-vessel.

The advantages of dense phase conveying over dilute phase include: considerably lower product degradation from particle-wall collisions and much lower energy costs because the air velocities are much less than during dilute phase flow. However, the pressure in a dense phase system operating in plug flow is often higher than a dilute phase system.
