Apr 18, 2018 It is interesting to compare this model to the one developed by Whiten and utilized by others for simulating cone crusher performance. Adopting the present nomenclature, the Whiten model is illustrated schematically in Figure 2. As seen, this model employs the primary breakage distribution and material bypass concepts.
Crushers are typically operated with constant closed side setting CSS or constant load None of the currently existing cone crusher models is truly useful for analytic control system design purposes Modelling in crushers is biased towards process dimensioning and equipment design i.e. steady-state models
The cone crusher is an indispensable equipment in complex ore mineral processing and a variant of the cone crusher is the inertia cone crusher. A real-time dynamic model based on the multibody dynamic and discrete element method is established to analyze the performance of the inertia cone crusher. This model considers an accurate description of the mechanical motions, the nonlinear contact ...
