The large movable jaw parts designed and manufactured from G reat Wall Casting are advanced.


Advantages of large crusher Fixed jaw

1.We applies unique heat treatment technology, has improved the hardness and impact resistance of crush jaw. Thus, product performance is largely enhanced.

2.Crush jaws are made of high strength steel. We optimized the production of crush jaws according to operation features of mainframe, which largely secures crush jaws’ stability and working life under long-time running.

3.We has strong manufacturing capacities of steel castings. We are able to abundantly produce crush jaw within a short period.
