What different Pneumatic Conveying Systems are there?

Here at STB Engineering, we have over 40 years of experience in pneumatic conveying systems. These systems are used to transport high volumes of granules and powders over long distances, having the benefit of being more versatile, hygienic and reliable than traditional mechanic systems. However, several different types of pneumatic conveying regimes exist which are suited for slightly different uses. Below we explain the five types of pneumatic conveying systems to help you choose the right one for your industry.

Dilute/Lean Phase

Dilute/lean phase systems can be divided into two pressure systems: positive and negative. Positive pressure or ‘blowing’ systems are the simplest of all pneumatic conveying systems. These use a blower or fan to deliver air into the pipeline, totally suspending the product in the air stream, before the powder is separated from the air stream at the other end by an air separator and filter.

Negative pressure systems, also known as vacuum systems, comprise of similar equipment but work in reverse, making them particularly suitable for carrying powder from multiple sources to a single point.
