Dense phase pneumatic conveying
What is dense phase pneumatic conveying?
Dense phase pneumatic conveying is a process that allows the transport of bulk materials or powders (by aspiration or blowing), without their particles being suspended in the air that transports them. This type of transport is used to move large quantities of a product over long distances.
In the following diagram we can observe the operation of a dense phase pneumatic transport system:
Type of dense phase pneumatic transport
This type of pneumatic conveying of powdery or granular materials is used in large-capacity transport for long distances. Its low transport rate preserves the properties of the transported material or the installation itself if the product has abrasive characteristics. The main advantage we can mention the transport flexibility in tight spaces, removing dust in the environment and minimal maintenance required.
- Semi-dense phase: it is appropriate with granulated or powdery products with a medium degree of abrasiveness, in short and medium distance conveying at medium speed.
- Continuous dense phase: it is appropriate for conveying granulated or fragile powder products and in short distance, low speed and low abrasion. This kind of conveying allows you to keep the properties of the product being moved in a perfect condition.
- Dense batch phase: it is mainly used in conveying highly abrasive granulated or powdery products and in large capacity and long distance. We form batches of product and air to reduce transport pressure, low speed and low abrasion. This kind of conveying allows you to keep the properties of the product being moved in perfect condition.
