Pneumatic Conveying: High-Performance Solutions for the Plastics Industry
The pneumatic conveying plays a strategic role in plastics logistics. Suitable for pellets or powders, this technology enables products to be moved from a storage area to a production area, even if they are several tens of meters apart. Using vacuum or pressure systems, it ensures fast, clean, and reliable transport, while reducing the risk of contamination and maintaining the material’s original quality.

Pneumatic Conveying Processes and Characteristics
Two distinct processes make up pneumatic conveying. Vacuum conveying operates in alternating cycles: one phase draws the material into a receiving cyclone, followed by a discharge into the hopper when the cyclone reaches capacity. This principle ensures a constant level in the hopper and a steady flow to the production line.
Pressure transfer operates continuously. This method is ideal for quickly filling large volumes. The system relies on equipment such as a booster pump, a turbine, or a rotary valve, as well as appropriate piping and a decompression cyclone.
Technical advantages include the ability to cover distances of up to 100 meters and overcome a 15-meter elevation difference using positive pressure. The systems are designed to prevent electrostatic charges by ensuring electrical continuity along the entire line. The vacuum units incorporate self-cleaning filters to capture dust.
The choice between suction and pressure depends on several factors: the nature of the products, the layout of the dispensing points, the volumes to be moved, and the installation constraints.
Industrial Equipment and Applications for Pneumatic Conveying
A pneumatic conveying system consists of several essential components: a suction unit, a stainless steel cyclone, aluminum piping, an injector or airlock, a suction pipe, and pressure relief systems. The design takes into account parameters such as bulk density, particle size, and the required flow rate.
Before implementation, real-world testing allows us to evaluate the material’s behavior and adjust settings, such as motor power or solenoid valve calibration. Engineering firms specializing in mechanical, electrical, and automation engineering develop customized solutions that can be integrated into production lines already in operation.
Once the equipment is in place, preventive maintenance plays a key role. It includes cleaning, inspecting components, servicing electrical systems, and checking automated controls. This regular maintenance extends the service life of the facilities and reduces the risk of unplanned outages.
These systems have a wide range of applications: feeding production lines, transferring material to intermediate silos, distributing material to multiple workstations, and integrating into recycling processes. Thanks to their flexibility and efficiency, these systems help optimize productivity while minimizing logistics costs.
With proven performance and great adaptability, the pneumatic conveying system offers a reliable solution to meet the growing demands of the plastics industry and ensure a smooth, controlled production flow.
