Understanding Pneumatic Conveying makes vital decisions much easier. A comprehensive, interlocking group of systems is offered to meet the needs of a wide variety of applications in every process industry involving bulk materials handling. From pebble lime to peanuts, from coal to baby powder - and everything in between - Mactenn has the technology, the hardware, and the experience to design and supply the proper technology group for reliability and life cycle economy. Selecting the correct pneumatic conveying regime for your requirements is a vital decision for a successfully designed system. Almost all 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.

Typical Conveying Regimes: Solid Dense Phase - Very low material velocity, pipeline full of material - an excellent regime for fragile materials. Discontinuous Dense Phase - Low material velocity - with high line loading ... material moves in plug flow fashion - best regime for most applications in which power economy, pipe erosion, and material degradation issues are important. Continuous Dense Phase (Moving Bed) - Higher velocity than discontinuous dense phase, but much lower than dilute phase. Used for handling powders that can be fluidized. Dilute Phase - Material velocity above the saltation velocity - no upper limit to the velocity - least attractive regime for operating economy - unsuitable for fragile or abrasive materials or materials with wide particle size distribution.
