Description of the case

Hammers for plaster boards (panels) made from 15mm Hardox® Extreme, laser-cut.

Prevoius material was 10 mm Hardox® 400 + 5 mm hardfacing


Lifetime increased by 30%. Less maintenance.

Cost is reduced by ~ 10% : increase of raw material cost but processing cost is reduced (hardfacing removed).

Shorter delivery time (no hardfacing piece by piece).


Increased productivity: only laser cutting versus cutting + hardfacing previously.

More competitive offer to end-user: cost / service life.

Healthier processing (no fumes due to hardfacing)

Potential is about 10 set (84 hammers per crusher) per year - 2,4 t/year/crusher

The main producer is recycling 45Kt/an of plaster waste (80% of the market) on 3 plants. They would like to recycle 100Kt in 2020.
