In the modern industry, there is no such thing as absolute single particle breaking, more crushing equipment is single grain crushing and many material combination of laminated crushing. For some broken equipment, such as cone crusher, and jaw crusher is a single particle in the feeding mouth extrusion, and in the crushing cavity of approximate parallel area are laminated and broken. For the impact crusher etc crusher, crushing cavity shape design is fully comply with more material between the principle of laminating crushing.
Therefore, the study of single particle materials broken just yourself can’t reflect most of the working principle of grinding equipment. So need to do some in-depth study of laminating crushing, jaw crusher in the crushing theory, for the development of new type of jaw crusher lay a solid theoretical basis. In recent decades, laminating crushing has become a crush engineering is an important area of research. For the further research of laminating crushing, for dressing on more crushing less grinding technology has an important significance. As laminating crushing becomes a new theory of the broken, the broken grinding as an independent engineering disciplines.
Liming crusher is the main research of run of mine ore crushed at the beginning of the material in the crushing cavity broken characteristics are mainly single particle breakage. The material into the feed, by extrusion of the moving jaw and fixed jaw broken at this moment is single grain crushing, after crushing materials due to the effect of gravity, such as flow down, in the process of flow may be broken, at this time also said that the single particle breakage. In the central crushing cavity, number of single particle breaking a lot. When the material flow to lower part of crushing cavity, it can be considered to be more material single particle breakage. The current domestic research on ore single grain early broken basic blank, in order to improve the working performance of crusher, early for single particle theory study, for the design of the jaw crusher cavity shape or improve provide abundant theoretical basis.
