PNEUMATIC TRANSPORT SYSTEMS

The pneumatic transport in dilute phase, also called  "low-pressure" phase,  is characterized by  very low efficiency ratio, usually less than  about 5 - 10 kg of product per kg of air.

The pneumatic transport in dense phase, on the contrary, is a technology developed for handling bulk materials in powder or in granules within longer pipes of 500 meters and with higher flow rates of 100 tons / h.

The peculiarity of the pneumatic transport in dense phase transport is the low speed and its high efficiency / air ratio, in addition to the fact that with this technology preserves the integrity of the material conveyed, also when it comes to mixtures of products.

As regards pellet transport, it is not always so simple to find the right solution. Therefore we have designed pneumatic conveying systems to transfer the pellets from the storage silo to a remote heating plant, which can also be placed 30 meters away from the pick-up point.

The pellet pneumatic transport systems are generally comprised of a suction motor capable of creating strong depression and thus extract a mixture of air and pellets from the storage silo. Pellet is conveyed into to a special hose, made of antistatic material.

  • Vacuum pneumatic conveying

    In the process of vacuum pneumatic conveying the pump or extraction unit creates depression inside the transport line- hoses and filter in the point of arrival of materials transported, which permits to produce air flux.

  • Pneumatic conveying under pressure

    Pneumatic conveying is based in fluid phase under pressure, when pushed, or depression in the extraction phase, caused by a blower inside of one or more holes.
