Optimization Of The Hydraulic Cone Crusher Cavity

Hydraulic cone crusher has the outstanding advantages such as low energy consumption,material crushing ratio,adjustable particle size and overload protection features.The material has strong non-linear hysteresis characteristics during the crushing process,and the dynamic characteristics of the crusher will change in a certain extent.It is no longer the best way to develop a new type of crusher by using pure rigid body dynamics analysis and particle material crushing experiment.Therefore,considering the nonlinear hysteresis characteristics of the material layer in the cavity of the crusher,the crushing process of the crusher can be analyzed more comprehensively,and efficiency and quality of the product optimization design can be improved effectively.The dynamic characteristics of crushing cone were studied under the action of hysteresis force of the material layer which is modelling by the Bouc-Wen model.The differential equations of the broken system established in three-dimensional space were solved by equivalent linearization method.The difference parameters were analyzed to obtain the impact to dynamic characteristics of the crusher.The static characteristics of movable cone liner were analyzed.The model established in Creo Parametric 2.0 software was imported into ANSYS Workbench.The imprinted surface was used to define the loading area of lining plate,and the load function was determined by considering the squeezing effect of the material layer on the liner to obtain the dynamic cone lining equivalent stress and total deformation cloud.The cavity optimization of hydraulic cone crusher was carried out.The key parameters in the crushing process of the crusher were analyzed and the reasonable design variables were determined.The relevant geometric parameters of the liner were taken as the design variables whose geometric constraints were taken as constraints of structural optimization.The crusher cavity was optimized to minimize the force of the liner by the target drive optimization module in ANSYS Workbench software.Considering the nonlinear hysteretic characteristics of the material layer in the cavity of the crusher makes study of the crushing process closer to reality,efficiency and quality are improved,and analysis of the same machinery and equipment is instructed.
