Abstract

At present, foreign production There are three major mining crushing equipment in the field of development goals. First of all, the new design concept, to break the conventional design ideas, technical innovation, continue to produce more and can implement online real-time monitoring of large equipment, rely on to compete with emerging markets countries. Second, increase the degree of automation equipment, to reduce the dependence on manpower; Finally, to reduce the the mineral crushing stage unit energy consumption, improve crushing efficiency. Compound pendulum jaw crusher performance, depending on the broken surface of the movable jaw plate every point in the state of motion, such as speed, acceleration and trajectory; these characteristics and location of each point in the design area. Which track the performance value with the regional variations in the crank-rocker mechanism institutional parameters and the resulting design space. Crank rocker mechanism parameters including the length of each rod, rack relative position is one of the key decision machine performance advantages and disadvantages. In the previous design study, in order to ensure the compound pendulum jaw crusher operation of the economy and reliability in the design often given to determine the structural parameters and operating parameters; adjustable parameters only the speed and the discharge opening width . Once these parameters are set, the machine produced, the crusher structure parameters and operating parameters and their ranges are fixed down, but not more regulation. In this paper, the above basic analysis of the studies, identify research ideas: crusher equipment manufacturing industry in China in the development and design needs, and take full advantage of the rapid development of computer technology, new design concept for the new compound pendulum jaw crusher design and research and development. In the second chapter, first of all, in some crank rocker mechanism rod size determined under the premise, to establish and connecting rod and analysis, the design of the broken point of the design space; design houses and area calculation and analysis of the motion characteristics of each point. Secondly, the speed of the movable jaw with rack and acceleration instantaneous center were analyzed. The results of the analysis of these calculations to determine the adjustable parameters and their range to provide a quantitative basis for design. In the third chapter, based on the second chapter of the calculation results of the analysis, the application of computer software ADAMS module, the movement mechanism of the compound pendulum jaw crusher modeling. And in the environment of the software on the compound pendulum jaw crusher kinematics simulation analysis; results show that the agreement with the theoretical results, the simulation results also confirmed the accuracy of the theoretical calculations. In Chapter 4, the analysis of the ore single particulate material experiences the initial three-stage crusher crushing assumptions; initial analysis of the ore experiences a single particulate material crushing, secondary crushing, ..., n times, ..., after the final crushing process proposed a three-stage crushing and current assumptions; the assumption of the state of motion within the design area suitable for crushing point; Then, in the flow characteristics of the inlet port at the beginning of the broken ore combined with a single particulate material, based on ADAMS software to find out the columns suitable for crushing and which gives this part of the optimization of the cavity design positions; changing the suspension height, observation of animals suitable for crushing point motion characteristics change and find new suitable for crushing points, cavity design a basis.
