PNEUMATIC CONVEYING SYSTEM

Product catalog summary

Overview: The document provides a detailed description of pneumatic conveying systems used for transporting materials such as granular plastic rejects, plastic waste flakes, and finished plastic items. It outlines the methods, components, and considerations for both positive and negative pressure conveying systems.

Conveying Methods:

Positive Pressure Conveying: Utilizes a Venturi feeder or rotary valve to introduce materials into a pressurized air stream. The Multiair blower is positioned before the feeder to push materials through the system.
Negative Pressure (Vacuum) Conveying: Materials are sucked into transfer pipes and conveyed to a separation cyclone. The Multiair blower is placed at the reception end to pull materials through the system.

Motive Power: Both systems use a Multiair blower unit to generate airflow, either pushing or pulling materials through the piping.

Modular Components: Kongskilde's systems are built from interchangeable standard components, allowing for easy assembly, modification, and capacity adjustments.

System Configuration:

Pressurized System: Requires a hopper, injector, or rotary valve for material supply. The Multiair is positioned in front of the infeed, and a cyclone separates air from materials.
Suction System: The Multiair is downstream of the cyclone, with a rotary valve providing an air seal. This system can handle materials from various storage types.

Dimensioning and Capacity: The document includes diagrams for dimensioning a pressurized pneumatic system, considering factors like conveying length, vertical lift, and extra bends. It provides guidelines for selecting the appropriate Multiair type and rotary valve based on specific requirements.

Key Considerations:

Capacity can be reduced by up to 20% depending on the percentage of regrind/flake material.
Extra conveying length must be added for vertical lifts over 4 meters and additional bends.
Example calculations are provided to illustrate how to determine the total conveying length and select the appropriate equipment.
