the three view drawing of the cone crusher, the main dynamic cone part (figure 11) is modeled by ug first, and then the whole cone crusher is modeled based on it (figure 12). the ug model is added to yade through the sub module of geometry, and the internal and external models of the cone crusher in yade are shown in figure 13.

oct 07, 2017 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. in this thesis real-time optimization is explored to the ...

the project of the vibration crusher with three degrees of freedom is proposed. the degrees are limited by the guide rails that hold the crusher body and cone against horizontal and spiral motions. the mathematical model for this project is obtained. the observations for the motion of the body, the cone and the unbalance vibrator are made in a numerical experiment.

that the wear rate of the dynamic cone is varied, and there is a best speed of the eccentric body. 1 . introduction. discrete element theory can describe the . mechanical behavior of discontinuous medium . such as ore. therefore, the study of crusher is more focused on the research and simulation analysis of discrete element theory[1]. in

inertia cone crushers are widely used in complex ore mineral processing. the two mass variables (fixed cone mass and moving cone mass) affect the dynamic performance of the inertia cone crusher. particularly the operative crushing force of the moving cone and the amplitude of the fixed cone are affected, and thus the energy consumption of the crusher.
