Rotor refurbishment breathes new life into Vecoplan shredder

At the start of a household waste processing line is a Vecoplan shredder, which is used as a bag opener. The rotor of this machine is subjected to heavy impact and wear from abrasive particles on a daily basis. As the rotor is located right at the start of the process, any wear has a direct impact on the rest of the plant.

When the rotor needed replacing, an alternative was already on the table, but it involved a long lead time and high costs. Overhauling offered an attractive alternative, but also presented a challenge: after the overhaul, the rotor had to fit exactly back into the existing shredder. Not only did the wear-resistant layer have to be correct, but the dimensions were also crucial. Even a small deviation can affect the cutting performance, the material flow and, ultimately, the plant’s capacity. Furthermore, no original production drawing was available, so we had to base our work on the existing geometry and our experience with similar refurbishments.

We carried out a full survey of the rotor, recorded the dimensions and worked step by step to repair the wear, without losing sight of the original geometry. For us, refurbishment means not just applying a new wear layer, but ensuring that a component functions as intended once again.

The result: the rotor is once again ready for a new period of operation and once more meets the required dimensions and tolerances. By opting for refurbishment instead of replacement, a significant amount of material has been saved and the need for an expensive new rotor has been avoided, whilst the installation continues to operate reliably.
