Vacuum conveying: The process of moving bulk dry materials, such as powders (sugar, flour, plasticpellets), within a factory using suction. The material is transferred in a network of tubing from the pick-uppoint or source to the point where processing takes place. Most vacuum conveying systems transfer theproduct based on a timed interval to the vacuum receiver. At the end of the timed sequence, the dischargevalve can open and the material conveyed can discharge in to the processing area. Plastic granules vacuum conveyingThanks to its their high performance and flexibility it was possible to replace 24 side channel blowers with3 Robox vacuum blower packages ensuring an energy savings of around 50% compared to the previouslyused equipment.Benefits at a glance Heavy-duty and extremelyreliable Highly efficient Long-life solution4

Applications Food packaging, PET production Pick & place Removal of impurities Pulp drying Paper converting: Suction pickup and transfer rolls use a vacuum to transfer the paper from theforming section to the press section, and guide the sheet from one felt to another in the press section.Robox vacuum blower packages are used to keep the sheet of paper adherent to the rollers so it canbe transformed.
