Searching for Ways to Optimize the Operation of Jaw Crushers

The crushing of materials is widely used in metallurgical, mining, building materials, chemical, electric power industry and so on. There are a large number of raw materials and reuse of waste treatment needed to be crushed every year. In the primary crushing stage, jaw crusher is the application of the main equipment. The performance of jaw crusher elated to the level of productivity and product quality levels, and developed energy efficient crusher can save a lot of costs and improve production efficiency. It is important to achieve high-quality, high yield, low cost, and low power consumption.
  Let’s take jaw crusher of PE250×400 as an example, based on computer graphics and virtual prototyping technology, optimization of working device with a capacity target, combination of experimental and simulation analysis of the breakage force. The paper established three-dimensional model of jaw crusher by Using Solid Edge software, and simplified the working device, based on virtual prototyping technology, exerted constraints on working device by ADAMS software, got the speed, acceleration, angular velocity, angular acceleration of the center of gravity of the moving jaw, and analyzed the rate of size on the performance of crusher. Based on the results of simulation, it got the trace and the trip value of moving liner, and it will provide reference for future design. We established the parameter model for working device in the ADAMS software, and established the capacity as the objective function, the length of crank and the link as the design variables, and built the relationship of the design variables, through the design study, it analyzed the crank length and link length impact on the capacity. By using optimal design, it gets the optimal value when the capacity is the maximum value.
  Finally, the breakage force was analyzed by using the combination of experimental and simulation methods. The conglomerate and siliceous rocks are used as the research object. After setting the test program, it got the maximum failure load of the conglomerate and siliceous rocks and their performance parameters by using uniaxial compression test. Through simulation it got the impact force of the inlet, middle, and the outlet of crushing chamber. This kind of research has provided an important basis for computing the maximum crushing force.sand washer : http://www.hxjq-crushers.com/8.htm
