Jaw crusher is a new European style long-life jaw crusher manufactured by Oupai Group on the basis of 30 years of crusher manufacturing experience in Oupai Group, using three-dimensional design theory. Compared with the traditional PE series jaw crusher, it has larger capacity and crushing ratio, larger input particle size range, more uniform product size, more convenient maintenance, and longer service life.

1. Symmetrical deep crushing chamber is adopted to maximize the range of feed size, capacity and crushing ratio.

2. Three-dimensional software is adopted to optimize crusher parameters and reduce equipment self-weight, so capacity is increased by more than 30%.

3. Bearing seat is designed integrally, so manufacturing difficulty is greatly reduced, and bearing life is increased.

4. There is a thick replaceable plate on the top of moving jaw to prevent moving jaw from being impacted.

5. Wedge is adopted to replace traditional gasket, so the adjustment is much easier and more reliable. Discharging size can be adjusted into desired sizes as per requirement within the adjustable range.

The movable jaw is hung on the mandrel and can swing left and right. When the eccentric shaft rotates, the connecting rod reciprocates up and down, which drives the two thrust plates to also reciprocate, thereby pushing the movable jaw to reciprocate left and right to realize crushing and unloading. This type of crusher adopts a crank double-link mechanism. Although the movable jaw is subjected to a great crushing reaction force, its eccentric shaft and connecting rod are not subjected to much force. Therefore, large-scale and medium-sized machines are often used in the industry. Come to crush hard materials. In addition, when this type of crusher works, the motion trajectory of each point on the movable jaw is an arc centered on the mandrel, 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 low, and the crushing ratio is generally 3-6. Because of its simple movement trajectory, it is called simple swing jaw crusher.
