A dynamic model of the working mechanism of a compound pendulum jaw crusher with clearance is established by the Lagrange multiplier method (LMD) based on the L-N contact force model and modified Coulomb friction force model. The correctness of the dynamic model is verified by MATLAB and Adams comparison simulation. and the best selection range of driving speed and clearance size is d... https://chefesquipmenters.shop/product-category/egg-turners/
