SP480 DTH Hammer
Working Pressure: 1.0-1.9Mpa
Air Consumption: 5.5/9m3/min
DTH hammers are used for blast hole drilling and blasting, mainly applied in Mining, Marble quarry or well drilling and other construction projects.
Main Feature:
New products designed based on mining condition in china, improving by advanced technology from global market.
Superior materials, advanced process,guaranteed quality.
Faster drillinq rate.
Hardness can be enhaced 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 amplitudeis lower, and the piston life is long.
