Water Well Drilling DTH Hammer Rustproof 80mm - 305 Mm Hole Diameter
Description
JCDRILL manufactures the finest and most efficient Down-the-Hole (DTH) hammers and bits for the mining,
construction and water well industries. Drill and blast engineers and water well contractors trust Rockmore’s
DTH equipment because of the precision engineering and high standards of drilling efficiency built into each
of our hammers and bits.
Optimal energy transfer is essential to DTH drilling efficiency – how much compressed air power is transferred
from the piston to the bit. That is why we have revolutionized air flow management in the new series high-performance
DTH hammers. Our patented Sonic Flow technology minimizes backflow and turbulence, enabling the piston to hit the
bit harder and with greater frequency. This means increased efficiency, more power, and faster penetration.
The streamlined design means fewer parts and easier maintenance.
Application
Advantages:
1. Out of the trouble of foot valve fracture and expansion and contraction.
2. Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% higher than the one with foot valve.
3. Simple structure, reliable parts, long life span, easy and cheap maintenance.
4. Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.

General.Operation
Series HD high air-press DTH are designed as a hammer drill. They differ from other rock drills,
however, through continuous operation down against the drill bit.Compressed air is led to the rock drill
thorough the dill tube string. Exhaust air is discharged through hole in the drill bit and used to flush clean
the drill hole. Rotation is delivered from a rotation unit and feed force from the feed is transferred the
DTH drill via the drill tubes.
