N2 - The twin-roll press is an important kind of press for dewatering. In a certain type of twin-roll press, cracking and fracture occurred on the roller after continuously running for 5 months. The fracture morphology, microstructure, micro-hardness, and mechanical properties of different fracture locations were tested. By considering the working conditions, structural characteristics, and loading distribution of the roller, and using the finite element method, the causes of fracture failure of the roller were analyzed. The results show that the failure mode was fatigue, and stress concentration caused by unreasonable structural design was the main cause of fatigue failure.
