Wear Protection Solutions for Mining

Plant components are at risk in all sections of mining and processing. Not only for mines and quarries but also for size reduction and classifying systems as well as for hydraulic raw material handling and the separation of tailings. KALIMPACT and KALMETALL wear protection solutions from Kalenborn Abresist reduce costs and avoid downtime.

KALIMPACT combines specific material strengths regarding resistance to wear and against destruction due to impacts. This results in individually tailored and particularly cost-effective solutions to guard against wear. KALIMPACT is also advantageous in applications where the material being conveyed should not be subjected to additional breakage. Lined plant components provide environmentally friendly noise and vibration insulation. Examples of this include discharge chutes for coal and iron ore in a port transshipment operation. Suitable design ensures that the elements can be replaced. Maintenance can be carried out rapidly.

Kalenborn Abresist fabricates KALMETALL chrome carbide weld overlay, standard grades of carbon and AR plate into wear resistant plates, piping and a variety of complete wear protected structures and assemblies. KALMETALL can also be adapted to specific uses by varying the alloy of the hard overlay welding. KALMETALL incorporates several hard overlay welded steel systems that consist of a tough basic body and hard overlay welding. The base metal provides the toughness of the system. Depending on the specific application, it is made of standard or special steels. The hard overlay welding is the wear layer. It consists of a C-Cr-Fe system with primary chromium carbides. The carbides provide the extreme hardness of the overlay welding. Depending on the composition of the alloy, the hardness may be up to 820 HV.
