Roll crushers


  • CR600 sizers

Sandvik sizers are used in open pit mining (ROM) for primary, as well as for secondary and tertiary crushing. The feed material is crushed either by counter-rotating rolls (CR610 center sizer) or between the rolls and the crushing plates by outwards rotating rolls (CR620 side sizer). The inclined lateral parts with integrated crushing combs allow a product feed of big lumps. Size reduction is attained by shearing stress and pressure, which are generated by high torques at the crushing roll.

  • CR800 hybrids

The Sandvik hybrids are a great choice for primary and secondary crushing of soft and medium-hard materials. In addition they can also handle materials that have tendency to be wet and sticky. The Hybrid can be used in IPCC installations.
