Every year, Germany produces around 10 million tonnes of cardboard and paperboard for the packaging industry. After their use, these items of cardboard packaging and boxes must then be reduced in volume before passing through the recycling process. This volume reduction step is performed by recycling companies and public recycling depots or in cardboard packaging and corrugated board factories.

Reasons for volume reduction:

  • Reducing costs of transportation
  • Optimum compression of material for feeding to existing pressed-waste containers or baling presses
  • Shredding of material for conveyor belt feeding

For these requirements, ERDWICH has developed a specialised product range – the EKZ and FKZ cardboard shredders – which can be supplied in a range of sizes.

The ERDWICH plant items have been designed as a perfect match for downstream transportation systems.

The EKZ has two shafts with independent drives: one high-speed shredder shaft and one slow-speed feed-in shaft. The feed-in shaft feeds the packaging to the shredder shaft, which then shreds the cardboard into fragments of the desired size. The machines can also easily handle fruit crates and polystyrene and other types of packaging.

In addition to the standard setup – a standalone machine that is either hand- or belt-fed – the EKZ cardboard shredder can also be set up to work in tandem with pressed-waste containers.  With the FKZ paperboard shredder, the material can be suction-fed directly into existing conveyor systems.

EKZ for optimized feeding of an existing disposal belt.

In a corrugated cardboard factory, there was an underfloor discharge conveyor with a width of approx. 1600 mm. The installation of new production machines resulted in cardboard boxes with widths up to 1800 mm. These resulted in constantly malfunctions in the disposal line. By pre-shredding the bows on the EKZ this source of interference could be effectively eliminated.
