QL50 Rock Drilling Water Well Mining DTH Hammer And Bits
DTH Hammers Features:
* New products designed based on mining condition in china,
improving by advanced technology from global market.
* Superior materials, advanced process,guaranteed quality.
* Faster drilling rate.
* Hardness can be enhanced to expand the lifespan of hammer, and
lower the cost.
* Huge impulse with low consumption of electricity.
* The modern theory is adopted in the structural design, which
makes the stress.
* Wave duration longer, the stress amplitude is lower, and the
piston life is long.
