Analysis of the structural design principle of crushing equipment

In modern industry, absolute single particle crushing does not exist, and more crushing plants are a combination of single particle crushing and multi-material laminar crushing. For some crushing equipment, such as cone crushers and jaw crushers, single particle crushing is carried out at the feed opening, while laminar crushing is carried out in the near-parallel area of the crushing chamber. For impact crushers and other crushing machines, the design of the crushing cavity shape follows the principle of laminar crushing between multiple materials.

Therefore, the study of single particle material crushing does not reflect the working principle of most of the crushing equipment. Therefore, in-depth research on laminated crushing is needed to enrich the crushing theory of jaw crushers and to lay a solid theoretical foundation for the development of new jaw crushers. In recent decades, laminated crushing has become an important research field in crushing engineering. The in-depth study of laminated crushing is of great significance to the new process of more crushing and less grinding proposed in mineral processing. With the emergence of laminated crushing as a new crushing theory, crushing and grinding has become an independent engineering discipline.

Our main study is the primary crushing of raw ore, and the crushing characteristics of the material in the crushing chamber are mainly single particle crushing. When the material enters the feed opening, it is crushed by the extrusion of the moving jaw and the fixed jaw, which is single particle crushing. In the middle of the crushing cavity, the number of single particle crushing is large. When the material flows to the lower part of the crushing cavity, it can be considered as more material single particle crushing.
