1266mm length dth hammers,
mincon air hammer
A kind of DTH hammer which is shorter but more efficient and energy efficient. we called them supper speed series DTH hammer.
High impact frequency, high drilling speed, low gas consumption.
Scope of application: drilling and blasting holes, guardrail holes, mountain reinforcement, anchoring holes, geothermal air conditioning holes, Wells holes and other fields in mines, quarries, highways and other projects.
1. The drill bit does not need nylon tube, thus saving the trouble caused by nylon tube breaking, breakage, thermal expansion and cold shrinkage.
2. Low impact energy loss, high impact frequency, and the drilling speed is 15%-30% faster than that of the same type of nylon pipe
3. The structure is very simple, the component reliability is good, the impactor life is long, the maintenance is simple, the cost is low.
4. Low air consumption, wind and oil saving, more than 10% oil saving than the same type of nylon pipe impactor.
