Dilute Phase

For continuous conveying, and batch conveying if the batch size is large, two
modes of conveying are recognized. If the material is conveyed in suspension in
the air through the pipeline it is referred to as dilute phase conveying. If the material
is conveyed at low velocity in a non-suspension mode, through all or part of
the pipeline, it is referred to as dense phase conveying. Almost any material can be
conveyed in dilute phase, suspension flow through a pipeline, regardless of the
particle size, shape or density.
