Pneumatic Conveying: Movement of dry materials with air

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

In dilute phase pneumatic conveying, particles slide through ducts at high speed with a large amount of air at low pressure. It can be either pressure or vacuum driven.

Vacuum pneumatic conveying, or suction conveying, is an efficient way to move solids in grain or powder form, which are fluidized by the air generated by the vacuum pump. They then flow freely through the pipes to their destination.

It is used across industries for the movement of powders and granules. It has several key advantages over mechanical conveying systems such as screw conveyors or bucket elevators.

1-It allows for transportation routes of highly variable geometry, without the limitations of the mentioned systems, which generally only allow for horizontal and vertical transport.

2-It leaves the installation much cleaner of residue from the transported product, upon completion.

3- It takes up less space and is cleaner for the surrounding environment, as it is a closed system.

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

Among the advantages of vacuum conveying are dust suppression and leak containment. It can also be applied in explosive atmospheres, with secure and graceful receivers, adapting the system to customized demands.
