5.5'' RC Down Hole Hammer Shank PR54/PR54R for Blasting
Product Introduce:
RC series reverse circulation DTH hammer is the latest developed
product of our company.It's mainly used for deep exploration
drilling and core sampling
Reverse Circulation (RC) drilling is used to collect mineral and
rock samples quickly and efficiently using a large rotary drill and
air compressor. Reverse Circulation (or RC) drilling is one of the
most frequently used methods of drilling used across the world as
it is more cost effective and efficient then other methods of
drilling. When compared to RAB (Rotary Air Blast) and diamond
drilling, RC drilling seems to be somewhere in the middle when it
comes to cost, time, quality of samples, technique and depth.
Adavantages:
1.Based on previous experience of ordinary hammer, combined with
feature of reverse circulation hammer, optimized internal structure
and ideal energy transfer,thus ensuring the series of hammers
drilling with fast,smooth and continuous sampling.
2.The internal structure is very simple with components of high
rigidity,thus ensuring long life and easy maintenance of the
hammer.
3.The collection tube adopts an integrative design and can be
replaced without disassembling the hammer with carburizing
treatment, it has good abrasive resistance.
4.Equipment with bits designed with patent.Simply by replacing the
drill bit, the same hammer can drill holes of different sizes
ensuring that the sample is not contaminated.
5.In difficult conditions such as loose soil,hard rock and plenty
of water exist, sampling can be done well.
