The pros and cons of cone crusher applications
A measure of the size reduction achieved for a particular crusher application is the reduction ratio. A cone crusher in a secondary crushing application will typically work with a 3.5:1 to 5:1 reduction ratio. Tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1.

Mathematical Modeling and Multi-Criteria Optimization of Design …
A prediction model of the crushing chamber performance was established through multiple nonlinear regression, and multi-objective optimization was performed, based on the genetic algorithm. The design of a single-roll crusher differs significantly from a cone crusher, so the results of these studies cannot be directly used.
Development of wear model for cone crushers
A model to predict the worn geometry of cone crushers was previously developed. In that model there was some disagreements between predicted and measured geometry and several effects were suggested to explain the discrepancy in the model. In this study the effect of shear forces along the crushing surfaces was implemented in the model.
