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.

Customised machine components for silica

The „Clean Cycle of Packaging”

Product: Specially developed paper valve bags guarantee optimum air circulation and product protection, even with bulk densities below 50 g/l.

Packaging: In close cooperation with LC Packaging, a machine is being realised that takes the individual physical properties of silica precisely into account.

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

Optimised compaction: Precise suction means that silica is packed so compactly that transport volumes and storage costs are significantly reduced

Safety standards: Automated process control eliminates manual intervention and thus reduces the risk of harmful dust exposure

Process stability: Continuous monitoring and adjustment of the vacuum parameters ensures an uninterrupted production process

Flexible machine options

Automated material handling: Robot-supported machines take over the precise feeding and handling of the bags

Customised machine configuration: Adaptable modules enable use with varying production volumes and material properties

Advanced safety features: Integrated sensors and real-time monitoring guarantee maximum process reliability and quality
