Complex oscillating gold ore crusher jaw directly suspended on the eccentric shaft, the eccentric shaft by the direct drive. The bottom of the moving jaw is supported by a thrust plate on the back wall of the frame. When the eccentric shaft is rotated, the movable jaw reciprocates the fixed jaw on the one hand, and at the same time, there is a great degree of vertical movement along the fixed jaw. The motion trajectory of each point on the moving jaw is not the same. The motion of the top is restrained by the eccentric shaft. The motion trajectory is close to the arc. In the middle part of the moving jaw, the motion trajectory is an elliptic curve. As a result of this type of crusher work, moving jaw movement trajectory is more complex, it is called the complex oscillating gold ore crusher, referred to as pendulum gold ore crusher.
In the course of work, the main part of the compound pendulum gold ore crusher horizontal movement of the top of the moving jaw is about 1.5 times the lower part of the vertical swing slightly less than the lower part of the whole moving jaw, the vertical swing horizontal swing 2-3 times. Because the upper part of the movable jaw is larger than the lower part horizontally, the upper part of the jaw cavity is strongly crushed. The large material is easily crushed in the upper part and the crushing effect of the entire jaw plate is uniform, which is beneficial to the improvement of the production capacity. At the same time, move the jaw closer to the fixed jaw, the extrusion process of the material, the top of the point also along the fixed jaw downward movement, but also to better hold the material in the jaw cavity, and to promote the broken material discharged as soon as possible . Therefore, under the same conditions, the production capacity of this type of crusher is 20% -30% higher than the simple pendulum gold ore crusher.
Complex oscillating gold used for the good return and have fun time for the user. The matter of lovely and ideal approach work as it bring good return. The matter of perfect essay leads a detail of paper writing service method.
