Simulation Analysis of Cavity Shape of Compound Pendulum Jaw Crusher

Taking the working device of PE1500 × 1800compound pendulum jaw crusher as the research object, 3D model of working devices of four different cavity shape compound pendulum jaw crushers is carried out by using SolidWorks, and then the kinematic simulation software ADAMS is imported to carry out the kinematic simulation, and the horizontal and vertical displacement change curves of four characteristic points of the lower part of the crushing cavity are obtained. According to the simulation results, the relative production capacity and the block-up coefficient of each broken layer of the jaw crusher are calculated under the same spindle speed and different cavity shape. The results show that the block-up coefficient of the crusher with curved crushing chamber is smaller and its relative production capacity is larger.
