Examples of DEM simulation of crushers include models of labscale cone crushers Herbst and Potapov, 2004, Quist and Evertsson, 2010 and single particle breakage in jaw crushers Legendre and Zevenhoven, in press, Refahi et al., 2010 all of which use bonded particle models.
Cone Crushers. It will be seen that the head and the bowl are parallel at the lower part of the crushing zone. The parallel space is deep enough, in conjunction with the speed of gyration, to ensure that no piece of ore can pass through it without being struck two or three times by the head before it falls clear.
Assumptions on the sizeclassification of the flow through the crusher and the velocity of the particles enable modelling the effect of the main manipulated variables ie closed side setting and rotational velocity It is also shown how the model may be discretized and
Obviously a small four stage crushing plant in which the third stage crusher was a 7 Ft Standard and the fourth stage consisted of two 7 Ft SHORT HEAD cone crushers would not improve economically by the use of one 10 Ft Standard cone crusher and one 10 Ft SHORT HEAD cone crusher in place of the 7
Cone crushers utilize this mechanism and are the most widely used type of crusher for secondary and tertiary crushing stages in both the aggregate and mining industry. The cone crusher concept was developed in the early 20th century and the basic layout of the machine has not changed dramatically since then.
Crushing Simulation In the context of this paper a simulation model for a size reduction device is an equation or equation set which allows the calculation of the product size distribution from the device for a specified size distribution of feed The model might be expressed as a simple algebraic expression as a matrix equation

Mowana mine crushing circuit through the design of a selftuning controller for the cone crusher and for prototyping, parameters of a PID controller were determined in the SimulinkMATLAB environment. The simulation involved the optimisation of the control model as a function of the cavity level of and the power drawn by the cone crusher.
A model was previously developed to predict the worn geometry of a cone crusher In that model there was some disagreement between predicted and measured geometry A suggested explanation for the discrepancy is that the flow model used is not accurate enough

A novel model of cone crushers is presented that can predict the flow and the size distribution of the output as a function of the primary manipulated variables and simulations of ESC control on
Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation and production of rock materials. Cone crusher control systems are widely used for machine protection, wear compensation and, to some extent, increasing production. These systems ordinarily focus on the crusher and not the yield of production process.
