Jan 30, 2021 Let us note that the well-known mathematical models used to analyze the dynamics of such crushers include a number of assumptions about the nature of their motion and the interaction of their elements with the medium processed, which, on the one hand, greatly simplify the analysis, and, on the other, can lead to the loss of descriptions of some ...
Jun 29, 2020 The mode of a two-mass cone crusher at the approaches to one of the Sommerfeld thresholds is considered. Frequency close to this threshold from low side provides the most efficient energy transfer from the unbalance to the crusher body. However, the stochastic model of crushing shows the possibility of breakdown such mode even after a very long stay on it.
