GOLDEN BAY CEMENT
HARDENING UP WITH HARDOX®
Golden Bay Cement wanted extra wear life on their limestone reclaimer’s 180 blades.
By working with Real Steel designers, the blades have now been re-engineered to be stronger and more protected from wear over time – without increasing their weight.
The reclaimer is an impressively large machine that pulls limestone down from a huge stockpile and onto a conveyer belt.
Golden Bay were finding the backing blades on the reclaimer were bending and wearing out too fast. The teeth were individually bolted on and only case hardened – meaning they were much softer on the inside.
Our Real Steel designers set to work creating a backing blade using Strenx steel to save weight. They added a Hardox bolt-on edge with built-in (rather than individual) teeth, which helped to protect from wear between the teeth. Finally, a scalloped design further reduced the overall weight.
The result is a far superior blade design that is outperforming and outlasting the original part – without adding any additional weight to the reclaimer.
The project is testament to the value of great design, steel selection, and teamwork.
