Ultra-light powders like carbon black, polyethylene fibres, color pigments and silica are a necessity for the production of manufactured goods such as lithium-ion batteries and rotor blades of wind turbines that sustainably advance future industries such as e-mobility and renewable energies. But they’re a huge pain for manufacturers – they’re messy, a potential workplace hazard and too expensive to waste. The market-leading and innovative VeloVac vacuum packers from Greif-Velox ensure dust-free, clean and safe bagging of these difficult-to-handle products.
Ultra-light Powders: small size, big outcome
They have particle sizes of less than 200 microns and a bulk density of less than 350 grams per liter, but they represent a major advance in the industry: ultralight powders.
- Carbon Black in its various forms is an essential component of, for example, car tires, anti-corrosion coatings and lithium-ion batteries, making it a key driver of global progress in e-mobility.
- Polyamide and polyethylene fibers are needed for the reinforcement of filters, rotor blades and lightweight components – and are thus needed in a wide range of innovative applications – from wind turbines for the expansion of renewable energies to the development of modern, low-emission vehicles.
- Silica – this versatile solid is crucial for the resistance of concrete, strength and thermal stability of glass or the higher resistance of wind turbines, for example. In industries like electronics, nanomedicine and energy storage, silica-based materials are crucial for innovation.
- Color pigments From paints and coatings to plastics and polymers to automotive - color pigments are needed in a wide range of industries; they literally bring color into life.
Bagging of ultra-light powders: a dirty business
All of these ultra-light powders have one thing in common: they are difficult to handle due to their physical and chemical characteristics. Manufacturers of ultra-light powders, especially carbon black or acetylene black, all have the same problem when using conventional bagging methods (especially pump packers): heavy contamination of the plant environment bringing along with it high cleaning costs, high logistics and complaint costs due to contaminated bags and increased risk for employees’ inhaling airborne dust. The bagging of ultra-light powders mostly leads to contamination of the entire plant environment, exposing employees to the hazardous dust. The bags and pallets themselves can also be contaminated, resulting in high cleaning and quality costs as well as damaging the brand’s reputation.
Stay dust-free – and safe
Greif-Velox VeloVac technology eliminates the mess by enclosing the process in a vacuum chamber, making the bagging of ultra-light powder entirely dust-free. Further features such as intelligent aspiration functions and the high performing, ultrasonic sealing unit Greif-Velox ValvoSeal ensure a safe process and handling.
So both the operators and the surrounding area are clean and protected from emissions. Save space – and logistics costs Unlike conventional methods that involve dirty and bulky bags (filled with a lot of air), operators can safely stack twice as many layers. Thanks to the dust-free vacuum process, the bags are highly compacted and clean, saving up to 75% on storage and logistics costs. Due to their brick-like, stable positioning, transport is safer and cheaper – and thus enables a significantly lower CO2 footprint.
Fill larger containers
With Greif-Velox VeloVac XL With our innovative Greif-Velox VeloVac XL model, users can now also fill FIBCs (“Big Bags”) with the vacuum method and benefit from the same advantages as with the VeloVac system for smaller containers: efficiency, cleanliness, employee safety, reduced storage, logistics and quality costs.
All in all the VeloVac vacuum packer gives you a significant competitive advantage over conventional pump packers:
Significant competitive advantages
- Maximum compaction reduces transport and logistics costs up to 75%.
- Optimal pallet appearance with firm, clean and perfectly stackable bags
- Maximum product safety due to the stainless steel design of the product-touching parts
- 100% dust-free bagging for high-purity products
- Immaculate brand reputation
