Abstract: This paper describes the development status of sizing crusher technology in China. The overall structure is basically mature. The wear-resistant material almost has the same property of foreign products. The reliability of key components has been significantly improved, and the control system has been continuously improved. Besides, the paper analyzed the technical similarities and differences between domestic and foreign sizing crusher equipment from the aspects of serialization, cavity structure, size adjustment, and tooth structure. Finally, the technological research focus of sizing crusher of the virtual crushing test and advanced design method was proposed.
