Bagging machine for silica

Precise silica bagging

Efficient, dust-free and safe packaging of ultra-fine silica (silicon dioxide)

Controlled dust production: Due to the high specific surface area, silica particles release a lot of dust even with minimal movement - our machine minimises the release exactly where traditional methods fail.

Systematically eliminate flow problems: Electrostatic charging and poor flow properties often lead to bridging. VeloVac technology ensures an even supply of material into the bag.

Tightly sealed packaging: The combination of precise vacuum suction and the ValvoSeal ultra-sealing unit ensures an absolutely secure seal that prevents contamination and product leakage.

Addressing extremely low bulk density: Fumed silica often has bulk densities below 50 g/l. Our solution reduces air inclusions and thus optimises the packing volume.

Due to its extremely low bulk density, fine particle size and tendency to become electrostatically charged, silica places high demands on bagging technology - and this is precisely where GREIF-VELOX comes in with the VeloVac.

Machine: The closed vacuum process not only minimises dust emissions, but also ensures continuously high compaction - ideal for a smooth production process.

VeloVac Vacuum packer: Innovation for silica bagging

The VeloVac was specially developed to meet the challenges of ultra-fine silica. The fully enclosed vacuum chamber ensures a dust-free process, while the integrated vacuum pump and CIP (Clean in Place) function significantly reduce both energy and cleaning costs.

Technical advantages of silica bagging
