The feasibility of using the BPM to represent the size reduction of rock experienced within a cone crusher chamber is explored by Li et al. [20]. The results showed that the BPM model was very useful even it consumes more computation time. At the same time, we also simulated the performance of the gyratory crusher through the …

3. Breakage criterion. The PRM approach has recently been used by Lichter et al. [14] to model the rock fracture predicted within a cone crusher. However, in that study the rock particles were described by polyhedral models and the fracture criterion and the parameters used to determine the distribution of the resultant post breakage …
It is worth mentioning that this good agreement is somewhat surprising since the simulation model is focused on body breakage, rather than surface breakage or abrasion. ...

The gyratory crusher is one of the most important mineral processing assets in the comminution circuit, and its production performance directly impacts the circuit throughput. Due to its higher energy utilisation rate for rock breakage than semi-autogenous (SAG/AG) milling, it is a common practice in operations to promote and …

Closed Circuit is defi ned as a combination of a crusher and one or more screens were all or parts of the material will pass the crusher. Over sized material will then be re-circulated to somewhere before the crusher and thereby fed to the crusher again to be re-crushed. Parts of the rock material will thereby pass the crusher more then once.
Thus the only essential difference between these models is in the treatment of the bypass for particles produced by fracture. Model Parameter Estimation. It is possible, in principle, to estimate the parameters of the model for once-through crushers using the same approach that Whiten, et al and Karra have taken for the cone crusher model.
