Safe and clean bagging of ultra-light powders in FIBCs

The VeloVac-XL vacuum system from Greif-Velox offers virtually dust-free and compact bagging of ultra-light powders thanks to an innovative technology: a completely closed vacuum chamber.
Until now, ultra-light powders such as carbon black or pyrogenic silica were particularly difficult to bag safely and compactly in FIBCs (”BigBags”) due to their nature. Maschinenfabrik Greif-Velox now offers a unique solution with the vacuum technology of the VeloVac XL: It ensures clean, fast and compact bagging, which minimises logistics and transport costs as well as product loss and increases work safety. At the same time, the use of the larger containers ensures economic and ecological advantages.

Innovative vacuum technology

The VeloVac-XL vacuum system from Greif-Velox offers virtually dust-free and compact bagging of ultra-light powders thanks to an innovative technology: The powders with particle sizes of less than 200 micrometres and a bulk density of 10 to 450 grams per litre are filled in a completely closed vacuum chamber. In contrast to pump packer systems, an atmospheric vacuum is generated in this chamber, which sucks the product directly into the FIBC without any losses. Any dust that escapes is automatically extracted and fed directly back into the bagging process.

Work safety, storage and logistics costs

Thanks to this particularly low-dust and clean bagging process, users save high costs for the often very costly cleaning of the plant environment. At the same time, employees are effectively protected from toxic or carcinogenic dust. Due to the up to 400 percent compaction of the bags compared to conventional pump packer systems, three quarters of the costs for storage and logistics are saved.

Cost and time savings

Time and costs can also be minimised by using FIBCs: Compared to bagging in 7.5-kilogram valve bags, users can fill up to 66 times the quantity into an FIBC at once with the gripper Velox VeloVac XL. For end customers, handling also becomes easier and more efficient: Larger bags can be processed and emptied more quickly; in addition, the cost savings for the packaging material are up to 30 percent. In addition, the VeloVac XL is characterised by its high performance: Four to ten FIBCs can be filled per hour, depending on the design of the product infeed and the product properties - in all desired bag sizes with a filling weight of up to 500 kilograms.

Automation levels

The modular design of the VeloVac XL is also flexible, depending on customer requirements: various automation levels are available. With the first, manual level, the chamber can be reached via a mobile lifting platform; the highest automation level as Full-Line guarantees fully automatic handling. Only the hooking in and closing of the FIBC has to be carried out by an operator, so that less than a third of an FTE (full-time equivalent) is required for the same output quantity compared to the manual variant.

Electromobility and renewable energies

The particularly efficient bagging of ultra-light powders by the VeloVac XL from Greif-Velox also significantly advances two important future industries: electromobility and the field of renewable energies. This is because high-quality carbon black (industrial carbon black) is an important component of lithium-ion batteries and other electricity storage applications. Pyrogenic silicon dioxide, also known as fumed silica, is an important material for the construction and expansion of powerful wind turbines, for example.

This event provides a presentation platform for innovations and advancements in processes for the manufacture of quality products made and processed from powder, granules, bulk solids and liquids – also for the environmental and recycling sector. Good reasons for visiting 1. 360° view of processing technologies Enjoy a 360° panoramic view of the entire process chain of mechanical processing technologies and talk with the best minds in the industry about the latest developments for the analysis, size reduction, screening, mixing, conveying, dosing and compacting of powder, granules, bulk solids and liquids. Whether energy efficiency, sustainability, gentle handling or process optimisation – as a driver of innovation, POWTECH always puts the spotlight on the hot topics in the processing technology sector. 2. Distinct focus on powder, granulation and bulk solids technology and the processing of fluids and liquids The compact layout provides easy access to the leading suppliers of basic processing technologies for powder, bulk solids and liquids: Whether you are looking for plant engineering, processing components, equipment for measuring, control and automation, nanoparticle technology products, safety and environmental technology or services for mechanical processing technologies, you are guaranteed to find what you need. 3. The perfect platform for live demonstrations, dialogue and new contacts POWTECH is more than just an exhibition. It’s where exhibits are tested live and specific solutions are developed with keen interest. Direct exchanges between experts mean that discussions are held on a level playing field and challenges are addressed directly from the ground up. This results in genuinely valuable and sustainable new contacts and business relationships. POWTECH is also the perfect stage for the next generation: As well as the key players, innovative young start-ups also present their new processes and product developments for the successful future of the industry. 4. Inspiration for tomorrow’s processing technologies Do you find that meetings, deadlines and cost pressures leave you with no scope for creativity during your daily work routine? The POWTECH 2023 supporting programme opens new perspectives. Be inspired by new impulses in our Expert Forum, special shows and pavilions, including topics such as explosion protection, food life science technologies, mandatory serialisation, and cleanroom technology. 5. POWTECH – the industry barometer 477 exhibitors from 29 countries and 7,688 trade visitors at the restart of POWTECH in 2022 underscore its importance for nearly all segments of industry, but especially chemicals, pharmaceuticals, metals and food. The process engineering supply chain continues to be a robust growth market. In 2023, POWTECH will reflect the fact that in many sectors, powder and bulk solids processing is being combined with fluid and liquid technologies to form an integrated process, and therefore the event specifically incorporates the processing and handling of liquids in its product range. Moreover, the important industrial sectors of cosmetics and batteries are being included in the exhibition for the first time. So don’t miss out. Make sure you are also part of the 2023 event with its new topics and technologies.
