| 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. |

|
| 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. |
