Vacuum technology for dust-free filling of fine powders

With the Velovac vacuum technology, the bagging of fine powders (particle sizes smaller than 200µm, bulk density of 10–450 g/L) takes place in a completely enclosed vacuum chamber. In this chamber, an atmospheric vacuum is generated through which the product is sucked into the vacuum bags. Any escaping dust is removed by suction and immediately redirected into the bagging process. In this way, none of the valuable product is lost. In addition, this process is particularly gentle on the product. Depending on the compaction potential of the material to be packed, a maximum product compaction of up to 400% is achieved, says the company. — Greif-Velox, Lübeck, Germany
