Once you’ve decided pneumatic conveying is the right solution for your process, understanding these modes of operation can help you to further distinguish which method of conveying is better suited for your application. Dilute phase or lean phase conveying takes place when material is suspended in air as it is blown or sucked through a pipeline.
The two main conveying systems are pressure and vacuum conveying for pneumatic conveying within the plastics industry. A combination of both systems is also possible, such as in the case of venturi material loaders. Pressure conveying refers to systems where the material is conveyed from the material supply to the destination via pressurised air.
To aid in your search for suitable material handling equipment, we’ll break down the three different types of pneumatic conveying systems. Dilute Phase Pneumatic Conveyors. The type of pneumatic conveyor you ultimately choose depends on the type of material you’re transporting.
By utilizing the right form of pneumatic conveying for your material and application, you will be able to move your product in a stable and continuous flow. Lean phase pneumatic conveying uses a high volume of air at low pressure to move product.
There are three types of pneumatic conveying: Dense Phase, Semi-Dense Phase, and Dilute Phase. The type of conveying is dependent on the material being conveyed. Abrasive and very fragile material will require a different type of system versus a material that non-abrasive and non-fragile.
Unlike other types of conveying systems, like belt, roller or slurry conveyors, a pneumatic conveying system doesn’t use direct contact or rely on mechanical means of transporting materials.
