Variation rules of speed and accelerated speed of points on the movable jaw have a great impact on the crushing performance of the compound pendulum jaw crusher, especially when the three kinematical characteristics, including displacement, speed, and accelerated speed of the movable jaw are combined together.
The points on the connecting rod correspond to those on the movable jaw plate. The crusher performance is determined by trajectory performance value of the points on the movable jaw plate, which is in turn determined by the position of points on the movable jaw plate and the size of the mechanism. The dimensional parameters include the lengths of rods on the crank slotted link mechanism, the frame position and the moving points position on the connecting rod. Consequently, the design scheme of the structure dimension parameters is one of the key determiners of machine performance.
Under normal circumstances, particle materials crushing on the upper part of the movable jaw requires certain displacement to meet the needed amount of compression needed for material crushing. In addition, the relationship of speed to accelerated speed must be appropriate. When the movable jaw plate moves towards the fixed jaw plate for material crushing, it will accelerate its movement if the direction of the speed accords with that of the accelerated speed. Thus, the force exerted on the materials will increase rapidly, leading to the impacting of the movable jaw and materials.Henan Hongxing impactor equipment will be your best choice.

It is known to all that the materials with certain hardness will bounce off each other when colliding. Whereas, since the movable jaw is connected with the machine, only the materials will bounce off. Chances are that materials will bounce back and forth in the crushing cavity if cannot be crushed or worse, pop out from the feeding port. If operators are nearby, significant casualties and property losses may be caused. This is the so-called 'material popping' phenomenon.
Since the parameters are certain, they cannot be adjusted once the machine is produced. Nowadays, though something with epoch features like the computer aided design is added to the traditional research and design method, the essence has remained the same. The researchers design the crank slotted link mechanism according to the trajectory of the points. The rod sizes are determined by the chosen movable jaw trajectory, the nip angle, etc.
To achieve proper relationship between the speed and the accelerated speed over the course of movable jaw movement: firstly, the ability to draw and analyze the chart of the speed and accelerated speed of the movable jaw plate is requested, which is also the reason why we analyze the relationship herein; secondly, jaw crusher capable of parameters adjustment needs to be designed. Consequently, the proper relationship of the speed and the accelerated speed can be realized.
