70,000 tonnes of highly corrosive potash salts per year: fine, prone to clumping and hardening, and highly adhesive. For a chemical company operating across Europe, these material properties presented a significant challenge in day-to-day material handling.

Corrosion and abrasion cause high levels of wear in conventional grab technology. Material build-up makes complete discharge more difficult, increases cleaning requirements and can lead to operational disruptions.

The challenge for METZEN: to develop a grab solution capable of withstanding these extreme conditions over the long term.

The experts at KRÖGER Greifertechnik, a METZEN product brand, analysed the material properties and operating conditions in detail. Working closely with a coating partner, they developed a specially formulated material composition for handling highly corrosive potash salts.

The specialist coating allows even highly adhesive material to slide off reliably. Additional polymer caps protect particularly exposed edges and further increase durability.

The result: the grab operates at full capacity – with no visible signs of wear.

Clean, reliable material handling reduces cleaning requirements and lowers operating and maintenance costs.

The project demonstrates what demanding material applications require: precise analysis, in-depth material expertise and engineering consistently tailored to real operating conditions.
