Pneumatic transport refers to a method of transportation of bulk material with air as a carrying medium, i.e. transportation of material through a pipeline driven by direct or indirect dynamic effects of the flowing air mass on the transported particles. •Chamber feeders •Conveyor troughs

  • Accessories
  • Auxiliary Elements

Types of stationary pneumatic transport

Low pressure transport – Medium pressure transport – High pressure transport – Pneumatic channel transport

As an example of the low pressure transport we can consider the ejector mixer. The transport distances are limited by transport air pressure to be used. Usual transport outputs of the low pressure transport are 0.1 to 2 t/h at transport distances of 30 to 40 meters.

The medium pressure transport uses blowers with the air pressure up to 0.1 MPa as sources of air and special rotary feeders as mixers.

The functional elements of the high pressure transport are cell and screw feeders. The screw feeders also known as Fullers pumps are suitable for smaller construction heights, for transport output of 60 t/h and distances up to 300 meters. However they are not suitable for the transport of abrasive materials.

The cell feeders however find the best application and are used for the transport of large volumes of material for long distances. Transport output depending on size of used feeder can be 10 to 150 t/h at transport
distance up to 1,000 meters.

Pneumatic channel transport is convenient especially from the point of view of energy saving and lower mechanical wear. This kind of transport is suitable for outputs up to 400 t/h of transported material. The slope of the channel is 4 to 10 %. It can be used for shorter transport distances where a natural decline can be took advantage of.

The above mentioned systems of pneumatic transport can be extended with elements of mechanical transport and thus it can meet the most demanding requirements of the customers.
