Jaw crusher is often used for primary crusher and secondary crusher, which can be used to crush all materials with compressive strength below 320 Mpa, such as basalt, granite, marble, limestone and so on. It is widely used in mining, smelting, building materials, highway, railway and other industries.

The XKJ Group is a well-known mining machinery manufacturer with 30 years of experience. Its jaw crushers are exported to 130 countries overseas and are highly praised by customers.

1. Complete models
According to the width of the feed inlet, jaw crushers are divided into large, medium and small. Large: inlet > 600 mm, medium: inlet 300-600 mm, small: inlet < 300 mm.

2. Equipment advantages
1) High performance. By optimizing the moving trajectory and cavity of the moving jaw, the output of this model is greatly improved under the same power.
2) Good stability. Through the optimization of the overall structure and counterweight of the model to determine the structure of flywheel and grooved wheel and the weight of counterweight block, the vibration of the model has been greatly improved. Compared with the jaw crusher of the same specification, it has higher stability.
3) High reliability. The heat-treated forged eccentric shaft, oversized bearing and E-frame make the equipment more durable and reliable.
4) Easy to operate and maintain. The advanced side guard bolt fixing system makes this type of machine faster when replacing the side guard; The reasonable machine structure makes it more convenient for this type of machine to adjust the size of discharge port and replace elbow plate, which can effectively shorten the operation and maintenance time.
5) Widely used. It is suitable for various crushing processes.

3. Vulnerable parts and materials
Vulnerable parts: elbow plate side guard, dynamic jaw static jaw spring bearing, triangular belt elbow plate pad
texture of material:
Spindle: 42 Cr Mo
Shell: ordinary A3 steel
Jaw plate and guard plate: high manganese steel
Elbow plate: ductile iron

4. Adjustment mode of the ore discharge outlet
1) Shim adjustment. Place a group of gaskets with equal thickness between the rear thrust plate support and the rear wall of the frame. By increasing or reducing the number of gasket layers, the ore discharge port of the crusher is reduced or increased. This method can be adjusted at multiple levels. The machine structure is compact and can reduce the weight of the equipment, but it must be stopped during adjustment. This adjustment method is often used in large jaw crushers.

2) Wedge adjustment. With the relative movement of the two wedges between the rear thrust plate support and the rear wall of the frame, the adjustment of the ore discharge port of the crusher is realized. This is a stepless adjustment method, which is convenient to adjust, saves time and does not need to stop for adjustment. This adjustment device is often used in small and medium-sized jaw crushers.
