Improved flow- and pressure model for cone crushers
The hypothesis put forward in this paper is that active control of the cone crusher’s eccentric speed and closed side setting (CSS) can increase throughput and/or energy efficiency of the SAG circuit. To verify this hypothesis, a dynamic model of a SAG mill-pebble crusher circuit was implemented. The dynamic unit models are based on The real-time cone crusher control has been traditionally limited to the narrow range of mining applications to control crusher load by manipulating the feed rate to the crusher [Borison and Syding 1976, Whiten 1984, Grujic 1996, Sbarbaro 2005].

Calibration and Validation of a Cone Crusher Model with Industrial Data
The resulting cone crusher model is a strong candidate for use in dynamic simulations of crushing plants for process control applications, flowsheet design, and operator training. Future work will include model calibration and validation against more diverse datasets, permitting the exploration of the effects of other operating variables, This study aims to analyze the impact of key structural parameters such as the bottom angle of the mantle, the length of the parallel zone, and the eccentric angle on the productivity and product quality of the cone crusher and optimize the crushing chamber to improve the crusher performance.
