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

VACUUM dense phase. Vacuum dense phase will present a quite similar setup than the lean phase one. However, in order to accomodate higher solids loads, leading to higher pressure drop, a vacuum pump will be used instead of a simple roots Blower. Very high vacuum will then be generated.

Most Vacuum Conveying System transfer product based on a timed interval to the vacuum receiver. At the end of the timed sequence the discharge valve can open and the material conveyed can discharge in to the process. There are two types of vacuum conveying. Dilute phase conveying and Dense phase
Pressure Offloading Systems Industrial Vacuum
Both systems are available on the Guzzler NX and the vane pump offload is available on the Guzzler CL Vacuum Trucks. Dense Phase Offloading System. An advanced offloading and recovery tool, the Guzzler Dense Phase offloading system combines applied pressure with high airflow for true dense phase conveyance of dry material up to 120 feet vertically.
Choosing a Pneumatic Conveying System:
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. ZENZ and OTHMER state that this pressure drop, for both dilute and dense phase conveying, is composed of six effective forces: 1.Friction of the gas against the pipe wall.

Although vacuum is most often used in dilute phase transport, it can also be used in dense phase system when economics and conditions dictate. Careful evaluation should be implemented to the optimal power drives particularly if a compressed air-driven central vacuum pump is planned to be used.

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.”

Depending on the transport pipe routing chosen, it can
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.
