  • Dense Phase pneumatic conveying systems

    A vacuum dense phase system is quite similar to a lean phase setup except that a vacuum pump allowing to reach pressure < -900 mbarg should be installed. The inlet of material is usually done through a sender hopper. No specific construction for the sender hopper is needed, which can be an advantage compared to pressure dense phase since the

    Hapman’s Model 42 Vacuum Conveyor offers large capacity conveying, up to 360 cubic feet per hour. Pneumatic conveying systems, which use an air stream to move materials through horizontal and/or vertical piping, come in two forms: pressure or vacuum.. Pressure systems introduce compressed air at the system inlet in order to push the material through the piping; vacuum systems apply a vacuum

  • Theory and Design of Dilute Phase Pneumatic Conveying Systems

    The calculations for the design of a dilute phase conveying sys-tem are based on determining the pressure drop that is gener-ated in the system due to the flow of gas and solids.

  • Dilute phase vs. dense phase pneumatic

    “Dense phase is advertised as more energy efficient than dilute phase, and generally this is true, if the system has been properly designed,” said Paul Solt. “The upper part of dense, just below saltation velocity, uses the lowest energy, but usually needs a compressor; and if the compressor isn’t properly matched to the usage a processor might not save any energy.”

  • Beware Dense Phase Pneumatic Conveying

    When a dense phase pneumatic material conveying system can’t meet the required increase in production without adding an additional system, often the production is increased by just pushing more compressed air into the transfer pipe. But, at some point, the critical particle velocities get so high that the system is now close to a dilute phase.
