Raw Materials Processing

Milling industry: Cast components for obtaining and preparing raw materials

As a result of the increasing inaccessibility of raw material deposits, the effort required to extract and convey these raw materials is becoming increasingly complex and challenging. Increasingly high-performance plants are required, bringing with them a corresponding demand for cast components that permit the effective continuous operation of these plants.

Siempelkamp supplies cast components for horizontal mills, which are used for the coarse grinding of various rock types in order to obtain ores such as gold, copper and iron ore. Depending on their intended application, the mills have an external diameter of up to 14 m and unit weights of up to 300 tons.

Component range:

  • Mill head segments
  • Mill heads in a single piece (up to approx. 8 m diameter)
  • Gear rims
  • Trunnions

Cast components for vertical mills

Vertical mills are used for cement and coal grinding. For these mill types, Siempelkamp casts grinding tables with diameters of up to 7 m and raw cast weights ranging from approx. 8,000 to over 200,000 kg.
