Pneumatic Conveying Systems

Considered today as one of the most efficient means of transporting products due to its safety, hygiene, precision and reliability, pneumatic conveying is the solution to a multitude of product movement problems.

Adaptable to any need in terms of capacity and length, this technology greatly simplifies the transfer of products between production sectors. With extensive experience in the application of this system, Prillwitz has specialized in the application of pneumatic conveyors for a wide variety of products, employing specific techniques for each of these.

Thanks to the vast experience in the implementation of pneumatic and mechanical conveying systems, Prillwitz has the necessary know-how to adapt the various machines to the particular product to be conveyed, through the application of specific techniques.

A regenerative turbine, a rotary piston blower or a fan can be used to generate the required air. In the case of using a compressor, it is possible to insert an air-to-air cooler for pneumatic conveying in order not to deteriorate the characteristics of the product.

Among our accessories for pneumatic conveying, the HSP rotary valves and HSD extraction sluices that ensure the loading and unloading of the product into the pipeline with absolute tightness stand out. VTN and VTNG valves allow diverting the pneumatic conveying lines to different discharge points.

  • Frequently asked questions:

    What is a pneumatic conveying system?

    A pneumatic conveying system is a way of moving a dry powder or granular product in bulk by mixing it with a gas, usually air, which carries it through a pipe.

    What is dilute phase pneumatic conveying?

    In dilute phase pneumatic conveying, the particles are conveyed through ducts at high speed with a large amount of air at low pressure. It can be either by impulsion or suction.

    What is pneumatic vacuum conveying?

    Pneumatic vacuum or suction conveying is an efficient way to move powdered or granular solids, which are fluidised by the air generated by the vacuum pump. They then flow freely through the pipes to their destination.

    Where is pneumatic conveying of solids used?

    It is used throughout industry for the movement of powders and granules. It has the following main advantages over mechanical conveying systems such as screw conveyors or bucket elevators

    1. It allows conveying paths of highly variable geometry, without the limitations of the aforementioned conveyors, which generally only allow horizontal and vertical conveying.
    2. They leave the installation much cleaner of the remains of the conveyed product, when completed.
    3. They take up less space and are cleaner for the surrounding environment, as they are closed systems.

    Benefits of dilute phase pneumatic conveying.

    The advantages of dilute phase pneumatic conveying are the flexibility of transfer in limited or small spaces, the suppression of dust in the environment and easy maintenance.

    Advantages of pneumatic vacuum conveying.

    The advantages of vacuum conveying include dust suppression and leak containment. It can also be applied in explosive atmospheres, with safe and graceful receivers, adapting the system to customised demands.
