Raw material extraction in small and medium-sized mining operations

  • The 220 SM / 220 SMi is the prime choice not only for use in small and medium-scale mining operations but also for routing work and infrastructure projects.
  • The compact, multipurpose surface miner extracts primary resources with an unconfined compressive strength of up to 50 MPa selectively and at a cutting depth of up to 11.8 in (300 mm).
  • The 7 ft 3 in (2.2-m) wide cutting drum unit is tailored precisely to the specific application and guarantees high productivity at low operating costs.
  • Primary resources are extracted in a single, environmentally sustainable operation without drilling and blasting, yielding material of the purest quality.
  • Windrowing enables the mined material to be deposited behind the machine in a continuous process.
