Met Dynamics, in association with Bear Rock Solutions, has developed a sophisticated model of gyratory and cone crushers that can greatly aid the optimisation of process performance through the mechanical design of the crushers and liners.. The Kinematic Crusher Model (KCM) meshes a mechanical description of the crushing machine with the breakage characteristics of the feed material.
• 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
