QL50 140mm DTH Hammer Bit for Open-Pit Mining and Water Well Drilling
DTH drilling is a percussion system driving a piston inside hammer
body with up and down motion by compressed air and transmitting an
intensive percussion energy to the bit to enable the drilling by
crushing the rock. Drilling method by DTH hammer exerts high
drilling performance especially for drilling hard rock and
contributes for shortening work schedule. Hence, this method is
widely utilized for foundation work, landslide prevention work,
quarrying services, marine civil work, etc.
KSQ makes and supplies the finest and most efficient Down-the-Hole
(DTH) hammers and bits for the mining, construction and water well
industries. Sansung DTH hammers transmit intensive impact energy
with low energy loss. This results in good rock breakage, high
penetration rates and high productivity. The equipment is designed
to give optimal hole quality, reliability, and long service life,
as well as the best blasting results and low total operation cost.
We can design and manufacture the personalized products to meet your specical apllication, such as changing the tungsten carbide insert profile (spherical, ballistic, etc.), face profile (flat face, concave, convex, etc.), and flushing holes.
Applications
• Underground mining
• Down the hole rock drilling
