Keep two concepts in mind when considering the use of pneumatic conveying. First, the system pressure decreases along the length of the conveying pipe. This means that the specific volume of the gas increases as does its velocity. These factors limit the conveyance length. Second, there is a minimum velocity needed to carry the solids.
Pneumatic conveyors either work with positive pressure or vacuum. With positive pressure conveying systems the material is pushed by the higher pressure on the feed side of the conveying system. Vacuum conveyors on the other hand pull the material with a vacuum that is created on the receiving side of the pneumatic conveying system.

Pneumatic conveying systems have been used by many industries to transport dry bulk particulate materials. The majority of installed systems are so called dilute phase systems where the particles that comprise the material are transported at low concentrations, suspended in the transport gas. Compared with other bulk handling systems they ...
of conveying system. Highly abrasive products and those subject to degradation move best through a high-pressure, low-velocity conveying system. On long distance, high-rate applications, a high-pressure, low-velocity system can offer energy savings. Magnum Systems Dense Phase Pneumatic Conveying System is such a system.

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 …
A trial is organized to design an industrial dense phase pneumatic conveying line for a material that is sensitive to breakage. The industrial line must be able to convey 8 t/h, the pipe layout is 50 m including 15 m vertical and has 5 bends.
Dense phase pneumatic conveying is a method for moving difficult, heavy (normally greater than 50-60 lb/cu ft) abrasive, mixed batch, or friable materials at a low product velocity. The system incorporates low gas volume at high pressure, conveying materials through an enclosed pipe in slug form at a controlled product velocity.

The most common positive pressure dense phase pneumatic conveying regimes are: Continuous Dense Phase. High Pressure – Low Velocity Material is conveyed below the saltation velocity in a moving bed flow pattern (rolling or plowing). Velocities are 10-25 ft/sec at the feed end, and 40-70 ft/sec at the terminal end.
Dense phase systems convey materials at slower velocity than traditional dilute phase pneumatic systems. Unlike dilute phase conveying, in which all the material is suspended in a high speed gas stream, dense phase conveying moves material in a slower but more concentrated manner, especially along the bottom of the pipeline.
