For large, hard rock ore crushing problems, based on the design of high input and output,Kefid developed a modern high-performance crusher with low power and high capacity - HJ series jaw crusher. 

 

Compared with the traditional jaw crusher, HJ series jaw crusher make precision optimized in the whole structure, moving jaw trajectory, the chamber cavity type so that the models yield and stability are greatly enhanced. The machine is equipped with forged eccentric shaft, oversized bearings, E-type rack, labyrinth seals and other quality components which make the device more durable and more reliable. Even in the face of basalt, granite, quartzite of high hardness rock, HJ energy jaw crusher can also crush them to medium-size, reducing stress and wear of secondary and tertiary crushing equipment and reduce production costs. 

 

In addition to the construction of gravel and sand production field, HJ series jaw crusher is also has significant advantage in black, non-ferrous mineral processing field.
