How can the machines in quarries be effectively protected against wear?
Excavators, loaders and dump trucks are very important machines when working in mines and quarries. Due to their intensive use, they are exposed to high loads, which is why they need to be protected with particularly resistant materials. We found this out in collaboration with a key customer. To effectively protect our customer’s machines against abrasion and thus extend their service life, we recommend the use of our wear-resistant materials KALMETALL, KALCAST and KALEN. They have proven to be the ideal solution.
A proven method for protecting excavator buckets
The metals used in excavators must not only be abrasion-resistant but also withstand heavy impacts. To further protect our customer’s equipment, we used KALMETALL liners. We adapted the welded hard surfacing material to be as abrasion-resistant as possible on the one hand and to provide the best impact resistance on the other in order to significantly extend the life of the excavator buckets.
How do you protect loaders in quarries?
Loader buckets in quarries are also exposed to high loads. We have found that the best possible solution for wear protection is to line them with the hard-cast metallic material KALCAST. This material is obtained by melting iron with varying amounts of chromium, nickel and carbon additives. Depending on the various quantities of the alloys, we can pre-determine the optimum balance between impact and wear resistance for the loaders.
Linings to protect dump trucks
To protect the dump trucks and extend their service life, we decided to use special linings made of welded hard surfacing KALMETALL. In our customer’s mines and quarries, however, raw materials are also extracted which stick to the trough of the tippers. For this application, linings with the technical sliding plastic KALEN are used, which ensures the safe material flow of the transported goods without caking.
