The RollSizer are capable of crushing medium-hard rock as well as sticky and soft material such as lignite, coal, clay, marl, limestone and similar raw materials.

Mode of Operation

The material is crushed by shear- and tensile forces generated by high rotor torques at a low circumferential speed. Due to the arrangement of the crushing tools the fines in the feed can pass through the crushing rolls similar to a roller screen without being crushed.


Compact, flat design:

  • Low overall height of crushing plant
  • Easy integration in existing plants

Low fines content in the final product:

  • Low dust generation
  • No dedusting system required
