Typical Sequences

Dome Valve

Unique Dome Valve permits choke filling of the Denseveyor Vessel.  Large diameter inlet flange permits unrestricted
vessel filling. 
No level probes or outlet Valves normally required.

Dome Valve closes through material at the end of the filling sequence, instantly seals to prevent conveying air
from escaping.

Dome Valve



Air is introduced at a controlled rate to destination without the need for continuous fluidization.

Opening cycle is repeated continuously until the transfer signal is cancelled.


The Four Basic Pneumatic Conveying Regimes

The Four Basic Pneumatic Conveying Regimes

A.  Solid Dense Phase  : Very low material velocity - pipeline full of material-an excellent regime for fragile materials.

B.  Discontinuous Dense Phase :- Low material velocity - pipeline almost full of material which moves in plug flow fashion-best regime for most applications in which power economy.  pipe erosion and material degradation issues are important.

C.  Continuous Dense Phase  :-  Highest velocity below the saltation velocity of the material conveyed-suitable for powder and narrow particle size distribution may not be optimum design for abrasive materials.

D.  Dilute Phase :-  Material Velocity above the saltation velocity - no upper limit to the velocity least attractive regime for operating economy-unsuitable for abrasive materials or materials with wide particle size distribution.

Selection of the correct pneumatic conveying regime for your requirements is a vital decision for a successfully designed system.  Almost all the applications will benefit from a regime providing the heaviest line loading and the lowest material velocity.  These attributes also provide the greatest conveying gas economies for efficient power consumption.

Our Scientific Approach to studying your conveying requirements assures you that the lowest material velocities are achieved consistent with any limitations of the material characterization.
