Product features
Strong, Stronger, Double Roll Crusher DRC
The FLSmidth Double Roll Crusher DRC withstands the toughest mining conditions while delivering consistent, high-performance crushing thanks to its working principle and several key features.
In the DRC the feed material is fed by a continuous feed arrangement into the middle of the machine between both rolls. The rolls are operating with 5 m/s or more and shear and compression forces crush the material between the roll in the gap. The crushed material is released through the crusher base frame onto a discharge conveyor. The floating roll enables the crusher to release tramp metal and adjust the gap by the hydraulic supported gap setting system.
Adjustment of the gap
The hydraulic system allows one roll to react to overload incidents by retracting and letting tramp metal or overloading material pass through the gap. Unlike with Roll Sizers, DRS therefore have less need for personnel entering the crushing chamber. This way the Double Roll Crusher ensures the safety of service personnel. Furthermore, the mechanism significantly helps with reducing downtimes.
High Versatility
The Double Roll Crusher crushes a wide range of material types reaching compressive strengths of up to 150 MPa and even above. It is less sensitive to wet and sticky material than Roll Sizers and can take in larger feed sizes making it the optimal primary crusher for soft and medium hard rocks.
