Vacuum Conveying Systems are an innovative design that can safely pass particles of materials, including hazardous or toxic products through a pipe using low air pressure. Used at the inlet is a metering device connected to a pipeline, receiver and exhauster. As there isn’t any positive pressure the inlet can cope with large particles being introduced into the system without fear of causing any damage. The pipeline is vacuum tight and an ideal solution when dealing with hopper loading applications.
In layman’s terms a vacuum conveyor system utilizes different pressures to move materials from one end of a pipe to another. The vacuum is the essential part of this futuristic machine and pulls the particles towards the negative pressure end. Large loads of dry materials can be moved from end to end, and powdered products are often transferred around a factory setting to the customers process using this type of suction. There are two main types of Vacuum Conveying, these are, Dense Phase Vacuum Conveying and Dilute Phase Conveying. The Dense Phase is used when slugs of materials are moved slowly along the system and is ideal for friable products or blended powders.
The Dilute Phase Conveying System is used when moving materials such as Sugar or flour and there is then an almost equal amount of product and air. There are many benefits to using this system, one of them being the cleanliness of the production and the lack of dust produced.
