In the production process of modern machinery industry, single-particle static pressure crushing and impact crushing technology in an absolute sense cannot be achieved. The crushing and grinding equipment we produce is more based on single-particle crushing and laminated crushing. For example, for the main working methods of jaw crushers and cone crushers, in addition to a certain form of single-particle crushing near the feeding port, most of the other areas are in the form of laminated crushing. of. For ball mills and high-pressure roller mills commonly used in production, they work entirely on the principle of laminated crushing. Therefore, it is not enough to study the crushing of single-particle materials to meet the working requirements, and it cannot specifically reflect the working mechanism of most crushing and grinding equipment. Therefore, we need to conduct detailed research on the lamination crushing method of crushing equipment, and lay a rich theoretical foundation for the discussion and development of crushing performance of crushing equipment.
In recent decades, lamination crushing has become a major research topic in the field of research on the working mechanism of crushing equipment. The in-depth study of lamination crushing has very important and far-reaching significance for the implementation of the new technology of "more crushing and less grinding". According to the difference in strain rate, the lamination and crushing of bulk materials can be divided into static pressure/quasi-static lamination crushing and dynamic impact lamination crushing.
