12 Inch Mining Rock Drilling Tools High Performance DTH Hammer
KSQ produce the broadest range of hammers, bits, and related
equipment. This means more choices for you. It means you can work
with the strongest support network in the industry, regardless of
your
equipment needs. It means that you can look to one reliable and
time tested source for all your equipment needs.
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 top hammer, 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 (Cluster drills) drill holes up to 70″ or
1778 mm.
Choosing the right hammer is largely determined by hole size and
type of rock formation. Ideally, the size of the hammer should
match the required hole dimension as closely as possible, leaving
just enough space for cuttings to evacuate the hole.
It is mainly featured in:
1.The strong energy of single impact and the low energy consumption
in rock crushing;
2.The weight ratio of Piston and Bit almost Reaches 1:1 to provide
long effective acting time, which leads to the improved efficiency
in rock crushing and the extended service life of the drilling
tool;
3.A good performance in central air exhaust and cuttings discharge,
which reduces the repeated crushing of rock;
4.A check valve device is available to drill holes finder water.
