1.High reliability:
Hydraulic overload protection system is reliable and safer,and the water proof is good.
2.Great geology adaptability:
Revolution can be adjusted without grade and different cutting wheels are designed for different ground conditions.So it makes great adaptability.
3.High rock breaking efficiency:
The special design of large eccentric cone crusher can raise the working efficiency with secondary crushing which also makes rock pieces easier to discharge.
4.Good construction operability:
Jacking speed and slurry flow can be continuously adjusted that makes it easier to achieve a balance of jacking speed and delivery of slurry flow.
