Compared with the simple pendulum jaw crusher, the compound pendulum jaw crusher possesses simple structure. Moreover, the movement path of each point on the moving jaw is different, the top movement is combine by the eccentric shaft, and its trajectory is close to arc.

2. As a professional mining machinery exporter, we will win your trust with our delivery speed, enterprises credit and product quality.

When the eccentric shaft rotates, on the one hand, the moving jaw swings back and forth towards the fixed jaw, on the other hand, it moves up and down to a large degree. And the jaw plate is liable to get abraded.

5.There’s a thrust plate at the bottom of the moving jaw to support the jaw on the posterior wall. The vertical travel of the moving jaw is comparatively large, that benefits the discharging especially these viscous and wet materials. At present, this kind of crusher is small and medium-sized. The moving jaw of the compound pendulum jaw crusher moves in different pace at the top as well as the https://www.gaugecase.com/product/ stainless steel pressure gauge factory lower end, crushing and discharging alternatively, thus the power consumption is even. At the time of crushing materials, the moving jaw bears great pressure which immediately impinges on the eccentric shaft.

3.Working principle of the compound pendulum jaw crusher

The moving jaw is hung directly in the eccentric shaft, driven by the eccentric shaft directly. It is light, compact and with higher yield capacity. As a result of its complicated movement path of each point on the moving jaw while it is working, it is called compound pendulum jaw crusher. The following are the good points and bad points of the compound pendulum jaw crusher:

1. Due to its large vertical travel, materials are both subject to squeezing effect and some grinding effect, exacerbating the material’s over-crushing phenomenon, augmenting energy consumption, generating large dust. In the middle of the moving jaw, the movement path is elliptic curve, the curve is longer when the trajectory is closer to the lower part.
