The crushed material is metallurgical, mining, building materials, chemical industry, electric power and other industries widely used as a process, every year a large number of raw materials and reuse waste treatment need to be crushed in the crushing stage, jaw crusher is application of the main device. Jaw crusher performance of the merits related to the level of production capacity and product quality level, developed energy-efficient crusher, can save a lot of money costs, improve production efficiency, for achieving high quality, low cost, low power consumption with significance. Paper is PE-250 × 400 compound pendulum jaw crusher for the study, based on computer graphics and virtual prototyping technology to production capacity as the objective function is optimized for organizations working device; through experiments and simulation analysis method of combining crushing force analysis. The use of Solid Edge software to build compound pendulum jaw crusher three-dimensional model, and its working device can be simplified, based on virtual prototype technology, using ADAMS working device corresponding constraints imposed on the model validation is correct, kinematics simulation analysis , to obtain the center of gravity moving jaw speed, acceleration, angular velocity, angular acceleration, and the velocity magnitude of the performance of the crusher. Through simulation analysis jaw tooth surface and movable jaw stroke trajectory characteristic values ??for future reference crusher design. In the ADAMS software to create institutions working device parametric model, establishing the production capacity of the objective function, the length of the crank and connecting rod length as design variables, design variables and to establish the relation between production capacity, research and analysis through the design of the crank length and connecting rod length on the impact of production capacity. Obtained using the optimized design production capacity of maximum body size of the optimal value. Finally, the analysis of the crushing force experiments and simulation analysis using a combination of methods to conglomerate and siliceous as the research object, using the uniaxial compression crushing experiments, setting experimental program were determined conglomerate and siliceous maximum failure load and get ore mechanical properties, in ADAMS simulation analysis through contact force of ore crushing chamber inlet, the middle position, the discharge opening at the impact force, compared to experimental and analytical results obtained in the crushing chamber crushing force distribution law To get a more reasonable maximum crushing force formulas provide the basis.
