Mobile jaw crusher is an important crushing equipment, which can be divided into two types according to its structural characteristics: compound swing type and simple swing type. The following is a comparison of the differences between simple swing jaw crusher and compound swing jaw crusher based on their working principles and characteristics.
Simple Swing Jaw Crusher Machine:
The movable jaw is suspended on the mandrel and can swing left and right. When the eccentric shaft rotates, the connecting rod reciprocates up and down. The simple swing jaw crusher machine drives the two thrust plates to reciprocate, thereby pushing the movable jaw to reciprocate left and right to achieve crushing and unloading. When the simple swing jaw crusher machine is working, the motion trajectory of each point on the movable jaw is an arc with the mandrel as the center. The arc radius is equal to the distance from the point to the axis. The upper arc is small and the lower arc is large. The crushing efficiency is relatively low. Because the motion trajectory is simple, it is called a simple swing jaw crusher.
Compound Swing Jaw Crusher Machine :
The upper end of the movable jaw is directly suspended on the eccentric shaft, which is used as the connecting rod of the crank-connecting rod mechanism and is directly driven by the eccentricity of the eccentric shaft. The lower end of the movable jaw is hinged to the thrust plate and supported on the rear wall of the frame. When the eccentric shaft rotates, the motion trajectory of each point on the movable jaw is a circular line from the suspension point, gradually turning into an ellipse downward. The lower it goes, the more biased the ellipse is, until the trajectory of the connection point with the thrust plate at the bottom is an arc line. Because the motion trajectory of each point on the movable jaw in this device is more complex, it is called a complex swing mobile jaw crusher.
There are obvious differences between the compound swing type mobile jaw crusher and the simple swing type mobile jaw crusher in structure and working principle. The compound swing type mobile jaw crusher has higher production efficiency and lower energy consumption, but the price is relatively more expensive; while the simple swing type mobile jaw crusher machine is more affordable, but the production efficiency is relatively low. Therefore, when choosing a movable jaw crusher, you should choose according to your actual needs.
