Description

3.5inch~12inch DTH Hammer with model DHD 3.5/340/350/360/380/1120 for quarries drilling

Product Description

The optimum range of hole size for blast hole drilling with DTH is 90 mm to 254 mm (3 ½"–10"). Smaller blast holes are generally drilled using tophammer, and larger holes generally use rotary machines.
In other applications, like foundation drilling, DTH hammers can be used with single bit in hole sizes up to 750 mm (30"). With multiple hammer units CD (Clusterdrills) drill holes up to 70" or 1778 mm.


All products are interchangeable with various products manufactured by Atlas Copco.

Advantages

dth hammer: dth hammer spare parts
More efficient energy transfer. Valveless air distribution. More reliable.
Faster drilling speed, 15%-30% higher than others. Simple design of the piston, long life
Lower air consumption and lower oil consumption. oil consumption is about 10% lower than others Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated.
Direct factory price Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.

Application

DTH hammers and bits are widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering. it has the advantage of high flatness, smooth hole wall, high rigid of drill rod and hammer, independent of high axial thrust, no limit of drilling depth, low cost of devices and easiness to maintain.
