thyssenkrupp RollSizers - The experts for coal crushing Double-RollSizers have proven to be the ideal machines for coal preparation in mines or in the power generating industry. Apart from the required product quality and the capacity, operators also focus increasingly on aspects, such as high availability, service life and ease of maintenance. In order to maximally meet all of these criteria, thyssenkrupp has developed its standard series for Double-RollSizers. Application of thyssenkrupp RollSizers This standard model range includes a total of 20 machines of various sizes and designs. In principle, the series can be divided into primary and secondary/tertiary sizers. In the primary crusher, a conveyable product (<300 mm) can be produced from the ROM material with a maximum edge length of 2.0 m in one step. In the following crushing stages, the required target grain size can be produced in the secondary or tertiary sizer. The compact design of thyssenkrupp RollSizers makes them suited for underground and mobile applications as well as for the implementation into existing crushing plants, e.g. in material transfer areas. For primary crushing, CenterSizers are used, in which the comminution takes place in the gap between the rollers, which rotate towards the center. By this working principle and the aggressively shaped teeth, it is possible to grip and process even big particles in the feed material.
