Sorting Plants for Paper and Cardboard

Equipped with our 4-wave ballistic separator PPK, the paper and cardboard sorting plants designed by us are genuine all-rounders. The result is material fractions with the highest degree of purity.

STADLER experience

“With more than a dozen paper and cardboard sorting plants built by STADLER over the past 15 years, we are experienced professionals in this field.”

Material properties

STADLER paper and cardboard plants are predominantly used for sorting large quantities of waste paper and cardboard from the commercial and municipal sectors.

Example process description

The paper mixture is fed – continuously metered – to the individual process steps. Ferrous constituents are removed from the overall flow by magnets. Large volumes of cardboard are separated by means of a screen or “paper spike”.
The remaining paper mixture is conveyed to the 4-wave ballistic separator PPK, which separates plastic and cardboard particles.
Deinking material that has not been separated is fed – if necessary via further separation steps (NIR) – into the sorting cabin, in which all product streams can be manually re-sorted. Finally, all sorted fractions are compressed by a baler.
