A generic model to explore the relationship between the parameters of cone crusher and liner wear is provided in this paper. Relative slide and squeezing between material and liner are considered based on the operating conditions, structure parameters, and material properties. The sliding distance of the material under different conditions is discussed. It is detailed how operating parameters and structural parameters influence the pressure on the liner surface. Considering that the process of liner wear evolves over time, the updating method of the geometry of crushing chamber is adopted. The wear model is derived based on Archard theory and is calibrated with the measured wear profiles of the liner from a PYGB1821 cone crusher. Experiments show that the predicted wear amount is consistent with the measured results. The wear model can be used to predict the wear state of liner and quantify the influence of operating parameters and structural parameters on the liner wear.

“…Numerical results show that speed, eccentric angle, and closed side setting (CSS) are important factors affecting energy consumption. 10 These make the performance of the crushers greatly improved, but also bring great economic value. However, crushers have low flexibility due to the limitations of their own mechanisms.…”

A robust controller is developed for the trajectory tracking control of a 6-DOF robotic crusher in task space. Firstly, the dynamic model including the mantle assembly and actuators is derived by Lagrange method according to the virtual work principle. In order to simulate the crushing behavior of cone crusher in the crushing chamber, the trajectory model of the mantle assembly is achieved by ADAMS. Then, a robust controller which contains the dynamic compensation is designed, and the convergence stability of the 6-DOF robotic crusher is strictly proved based on Lyapunov stability theory. Finally, the co-simulation is used to verify that the proposed controller can solve the problem of model uncertainties and external disturbances well. Meanwhile, numerical simulation results of the 6-DOF robotic crusher illustrate the proposed controller is able to effectively reduce the trajectory tracking errors compared with the computed torque controller.

“…As one of the typical crushers, cone crusher is an indispensable piece of equipment [3]. It is typically used in secondary and tertiary crushing stages in minerals processing plants [4,5]. The mantle and concave are the two main crushing parts.…”

Dynamic Modeling and Analysis of a Novel 6‐DOF Robotic Crusher Based on Movement Characteristics

This paper proposes a novel 6-DOF robotic crusher that combines the performance characteristics of the cone crusher and parallel robot, such as interparticle breakage and high flexibility. Kinematics and dynamics are derived from the no-load and crushing parts in order to clearly describe the whole crushing process. For the no-load case, the kinematic and dynamic equations are established by using analytical geometry and Lagrange equation. Analytical geometry is mainly used to solve the inverse kinematics and then establish the velocity relationship between generalized coordinates and actuators. Lagrange equation which takes into account the weight of the mantle and actuators is used to solve driving forces of actuators. For the crushing case, crushing pressure is related to the compression ratio and particle size distribution, but the selection and breakage functions should be established first. Because the trajectory model of the mantle is difficult to be established by using analytical method, it can be obtained by an eccentric simulation. The results of input velocities and driving forces of actuators are distinctive due to the eccentric angle and selection of the initial position. Finally, the proposed approach is verified by a numerical example and then the energy consumption is calculated.
