PneumaticconveyingJetsolutions provides the best solution to transfer bulkmaterials, using pneumatic conveying systems adaptedtotheprocessandtheproduct.Ourtransfersystemsaredesignedtoworkinnegativeorpositivepressureandtowork in dilute or dense phases. Depending on theprocessthegasusedtoconveytheproductcanbeairornitrogen.Thepneumaticconveyingsystemisanefficientmethodto move fluidizable powders or granulates betweendifferent points. This technology allows the dischargingofbulkmaterialscomingfrombags,FIBC’s, IBC’s,trucksandsilos,tofeedreactors,tanksandotherelements.

PositiveandnegativeconveyingpressureNegative pressure or vacuum conveying, is usednormally to transfer delicate and dangerous products,this technology avoid the contact between theproductand the environment in case of leaks on the piping. Inthe other hand positive pressure, also denominatedoverpressure conveying is used mainly for heavymaterials such cement, sand or salt or to protect theproductfromtheenvironment.
DilutePhaseThe dilute phase can be defined as the continuoustransfermethod,topushorpullpowdersfromthepointAtoB,usingasufficientairstreamspeed.Thisphaseischaracterizedmainlyforitshighspeed,lowpressureandlow ratio between product and the gas. Resuming thistechnology uses a large air quantity to convey a smallproductquantity in continuous.Almost all thepowderscanbeconveyedusingthismethod.
DensephaseThe dense phase uses low volume of gas and highpressure (for positive conveying) or high vacuum (fornegativeconveying)andaratiomassofproduct/gasveryhigh(upto80-100).Thistechnologyrepresentsthebestchoicetoconveyabrasiveandfragileproducts. Conveying
