Pneumatic Conveying

TurboKopar’s Pneumatic Conveying is one of the most efficient and economical ways of handling powdered materials. A well designed pneumatic conveying system is often a more practical and economical method of transporting materials from one point to another than alternative mechanical systems because :

  • Pneumatic systems are relatively economical to install and operate;
  • Pneumatic systems are totally enclosed and if required can operate entirely without moving parts coming into contact with the conveyed material, which makes it relatively clean, more environmentally acceptable and simple to maintain;
  • Pneumatic systems are flexible in terms of rerouting and expansion. They can convey a product at any place a pipe line can run.

Four different pneumatic conveying systems can be designed depending on the nature of the material, conveying distance, conveying volume and the overall process in which the material flows. By using one or any combination of these systems an optimum solution is determined.

The four pneumatic conveying methods are

Solid Dense Phase:

In this system the pipeline is full of material. It is an ideal solution for fragile materials and where the application requires that both the particle size as well as the structure remains intact during transport. This system is also suggested when the required conveying capacity is low and distances short. Few materials that TurboKopar has handled using this technology are Copper Concentrate and Power Plant Fine Bed Sand.

Pulse Dense Phase:

This process uses low material velocity wherein a pipeline almost full of material moves in plug-flow fashion. This solution is ideal for materials that are abrasive in nature. It is one of the most efficient ways of conveying materials. Some of the materials that TurboKopar has handled using this technology are Fly ash, Plastic Granules, Nickel Concentrate etc.

Most of TurboKopar customers have selected the pulse dense phase system as the most efficient, competitive and reliable solution. Hundreds of TurboKopars’ pulse dense phase systems are currently in operation around the world.

Fluidized Phase:

This process is suited for highest velocity below the saltation velocity of the material conveyed. This makes fluidized phase perfect for powder and narrow particle size. However, it is not the optimum design for the distribution of abrasive materials. TurboKopar has handled pulverized bed Flyash, Cement, Limestone, Caolin Clay, Chalk etc using this technology.

Dilute Phase:

This process involves Material Velocity above the saltation velocity with no upper limit to the velocity. In terms of efficiency, this is a less than ideal solution; however, this method is suitable for non-abrasive materials and materials with similar particle size distribution.TurboKopar has used this technology to handle the conveyance of Sugar, Limestone (large particles), Dolomite, Titanium Oxide etc.
