1. High Performance. The model has a large output, by the optimization of the trajectory of movable jaw plate and the cavity, to determine the optimum
engagement angle and stroke property values, so that the productivity of this model has risen considerably with the same power.
2. High stability. By the optimization of the whole structure and the counterweight section to determine the structure of flywheel and driving wheel and the weight
of counterweight section, so its function of vibration has been greatly improved. Compared with the same unit jaw crusher, HJ series possess a greater stability.
3. High reliability. Heat-treated forged eccentric shaft, extra large bearings, “E” frame, labyrinth seals, etc, making equipment sturdy and durable, more reliable.
4. Easy maintenance and operation. Advanced side fender bolt system makes the replacing of the side shield more faster; reasonable machine structure makes it
more convenient for discharge setting and replacement of toggle plate. All this can effectively shorten the operation and maintenance time
5. Wide application. HJ series jaw crusher has a compact structure, compared with the same unit jaw crusher, it possess a smaller footprint. So that it can play a
greater role in the limited space to suit a variety of crushing process.
6. Finite element analysis technology is adopted to make the crusher much stronger.
7. Crusher chamber adopts "V" structure which could make actual feed width comply with the nominal one.
8. Bearing with larger model and higher load are used. All jaw crusher is equipped with larger bearing compared with same model of normal jaw crusher. Its higher load capacity and effective
oil seal will lengthen the life of bearing.
9. A newly designed tooth-shape side plate, makes the available area of jaw plate longer, and enhances the capacity.
10. Pressing bar and support type are used to fix jaw plate.
11. Heavy type protecting plate is installed for bearing seat, accidental damage of bearing seat is avoided.
12. Supporting bar under jaw plate protects movable jaw and frame from being worn down.
+  Working Principle
The crushing method of European type jaw crusher is dynamic squeeze. The working principle is: the electromotor drives the belt and pulley to make the movable jaw move back and forth,
up and down through the eccentric shaft. The raw material is squashed or split when movable jaw plate moves towards fixed jaw together with movable jaw. When movable jaw and
movable jaw plate turn back by eccentric shaft and spring, the raw material, which is squashed or split before discharges from the bottom outlet under jaw plate. The bulk-production comes
true while electromotor rotates continuously and the movable jaw crushes and discharges the raw material periodically.
