Mining
Mining comprises the exploration and development as well as the extraction and processing of solid, liquid and gaseous raw materials.

Solid raw materials are extracted above and below ground

  • in open cast mines by excavating open clay, gravel and sand pits or in quarries as well as
  • in underground mines.

Within the framework of the extraction and processing of the raw materials, machines and installations are used where the goods are handled and crushed. This involves enormous wear stress for the machine and installation components.

The HARDTOP material programme guarantees a long service life for the components. This applies for both

  • steel castings,
  • heavy-duty castings as well as
  • bimetal castings.
