Choose the Correct Pneumatic Conveyors for Efficient transferring of Materials

The Pneumatic conveying System is a method of transferring material substances through an isolated pipe by air. Substances like powders, granules, and other dry bulk materials pass through an enclosed horizontal or vertical conveying line. The phenomenon is particularly based on characteristic of the substances like density, particle size, throughput capacity, number of sources and number of destinations.

The Pneumatic can be considered more efficient in reference to the mechanical conveyors as it has a customized modification to fit in any existing equipments. Also, It occupies less space compared to the traditional ware. Categorized into two types:

  • The Non Suspension flow typed Dense Phase Conveying system is a plug flow system. The substances are filled in a pressured vessel of air or any gas that is utilized for conveying/transfer. This method is used for large distance conveying with a ratio of upto 100Kg substance to 1Kg air range.
  • Whereas dilute phase is a suspension flow, corresponding velocity is applied as per different materials and their characteristics. The ratio material into air varies as upto 10Kg/Kg air.
  • For a comparatively shorter distance of conveying, dense phase conveying system is used.
  • In order to maintain multiple feed points, Pneumatic vacuum conveying is used. Any kind of leakage would be preventing inward, that helps more in hazardous product conveying.

For an industrial environment, not all process would require equivalent processing for handing bulk material. There are customizable principles that can be applied over Pneumatic Conveying Systems. How to choose the right Pneumatic Conveying system for a particular application? A set of factors to be considered while applying pneumatic convey systems to your workplace are enlisted below:

Material characteristic

Resources to be processed in a particular phenomenon can have different features like invariable density, friability, cohesiveness, static charge, toxicity, melting point etc. This would help to correctly select the application type of Pneumatic conveyors based on either pressure based or vacuum based.

Environment of application

Where to install the pneumatic systems, like say your environment is based on barge , plant or any ship environment. How to plan the installation more efficiently with bends and space occupancy, pipeline routing and length fit.

Physical Constraints

The environment with low headroom can affect your equipment. Hence the perspective should be clear to make use of alternatives to settle your equipments at such places with these constraints.

A high customizing option is required to make the maintenance access easier for the equipments also, the supply of vessels, especially on board or offshore rigs/platforms, self discharging cement carriers and other waterway bulk carriers space if its limited. Considering the transfer rate of material for the system must also meet your application requirement.

The Conclusion

  1. The resource of material perfectly meets requirement consideration for pneumatic conveyors, now for the application of the phenomena can be first considered with respect to the cost effectiveness.
  2. The further question arises for the selection of phase either dilute under pressure or vacuum.
  3. The air leaking phenomena either inside or outside would result in passive effect. For example: air leakage in case of a toxic hazardous substance could be dangerous so considering this point way before application can be a safer choice.
  4. Material is cohesive and tends to build on surface or remains grainy. For some case it may be better in opting vacuum for the particle tends to pull apart.
  5. For in case of a dense phase conveying system, like when using cement, fly ash, barite as a resource, the application will require smaller line diameter, than a comparably sized dilute phase system.
  6. The dense phase not only requires less air volume but in a long system, system diameter line sections are much lighter, making maintenance and implementation easier.

There are several other properties to consider when opting for Pneumatic Conveyors for efficiently conducting application work depending upon different factors.
