Five Pneumatic Conveying FAQs

Pneumatic conveying is widely used to move powders, granules and other dry bulk materials through enclosed pipelines. Here we outline five common questions to help clarify how pneumatic conveying systems work and what businesses should consider when selecting one.

What Is Pneumatic Conveying?

Pneumatic conveying uses airflow to transport dry materials through pipes. It replaces the need for mechanical conveyors and can be adapted for a wide range of production environments. Most pneumatic conveying systems operate as either dilute phase or dense phase, depending on material behaviour and required transfer rates.

Which Materials Are Suitable?

Many powders and particulate products can be handled, including food ingredients, chemicals, plastics and minerals. The suitability depends on particle size, abrasiveness, moisture content and how the material behaves when aerated. Here you can read more about pneumatic conveying.

What Is the Difference Between Dilute and Dense Phase?

Dilute phase uses higher air velocity to keep materials suspended, making it useful for free-flowing products. The dense phase uses lower air velocity and higher pressure, pushing material in slower-moving slugs. Dense phase is often chosen for fragile or abrasive products due to reduced wear and gentler handling.

How Far Can Materials Be Conveyed?

Distances vary depending on pipeline layout, air supply and material type. Industrial installations may run from a few metres to several hundred. Websites such as aptech.uk.com/pneumatic-conveying-systems provide helpful examples of typical system configurations.

What Maintenance Is Required?

Routine checks ensure pipelines are clear, filters are functioning and air supply remains stable. Regular inspections help maintain energy efficiency, prolong equipment life and prevent unexpected downtime.
