Differences between the frame structure of the traditional compound jaw crusher and the double chamber jaw crusher

The difference in power mechanisms between the two types of crushers has led to their installation base - the structural differences of the frames. A typical conventional compound pendulum jaw crusher frame is generally an integral casting frame.
The upper and eccentric shafts of the double-chamber jaw crusher make the double-cavity jaw crusher a standard fixed-length four-bar mechanism, which provides a more realistic theoretical model for the accurate calculation of various parameters and also enables activities. The characteristic values ​​of the jaws in the height direction have a more ideal distribution, which improves the performance of the whole machine; but because the rocker, the eccentric shaft and the fixed jaw are the force transmitting components that transmit the crushing force to the frame, The change in the installation position and installation method of the crusher also led to a major change in the structure of the crusher. The traditional overall frame is the upper and lower combined frame. The upper and lower frames are connected by screws and pins, and the whole structure is welded.
The difference between the structure of the double-cavity crusher and the conventional compound pendulum jaw crusher has led to a huge change in the frame structure and the force of the frame. The research results of the above traditional compound pendulum jaw crusher frame have certain significance for guiding the design of the frame and improving the quality and performance of the frame, but the research object guiding the subject--the design of the double-cavity crusher frame Has a lot of limitations. Therefore, in order to understand the working performance of the double-chamber jaw crusher and the mechanical characteristics of the frame and to improve its structure and optimize the design, it is necessary to conduct a new in-depth study.
