    Jul 01, 2016 The dynamic fragmentation of rock is essentially a process of energy consumption, and energy dissipation analysis is essential to elucidate the mechanism of rock dynamic crushing. Furthermore, energy consumption is not only one of the important indicators to evaluate rock breaking efficiency but also forms a useful metric when optimizing the

    Nov 06, 2021 Rock excavation is a dynamic process where rock is dynamically loaded by mechanical cutting tools. Previous researches have shown that rock strength in dynamic loading is greater than that in static loading. However, existing prediction models for mechanical excavation of rock do not take into account the dynamic features of the rock. This issue has the potential to deliver misleading outcomes

    Dec 26, 2015 In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface
