Rock Breaking Equipments SRC531 RC Drilling Bits For Water Well
Drilling
Basics of Reverse Circulation Drilling:
(1) RC drilling uses rods with inner and outer tubes, the drill
cuttings are returned to surface inside the rods. The drilling
mechanism is a pneumatic reciprocating piston known as a hammer
driving a tungsten-steel drill bit.
(2) RC drilling utilizes much larger rigs and machinery and depths of
up to 500 meters are routinely achieved. RC drilling ideally
produces dry rock chips, as large air compressors dry the rock out
ahead of the advancing drill bit.
(3) RC drilling is slower and costlier but achieves better penetration
than RAB or air core drilling; it is cheaper than diamond coring
and is thus preferred for most mineral exploration work.
(4) Reverse circulation is achieved by blowing air down the annulus of
the rod, the differential pressure creating air lift of the water
and cuttings up the inner tube which is inside each rod. It reaches
the deflector box at the top of the drill string then moves through
a sample hose which is attached to the top of the cyclone.
The drill cuttings travel around the inside of the cyclone until
they fall through an opening at the bottom and are collected in a
sample bag. For any drill hole there will be a large number of
sample bags, each one marked to record the location and drilling
depth that the sample was obtained.
The collected series of sample bag cuttings are later taken for
analysis to determine the mineral composition of the drill hole.
The analysis results of each individual bag represents the mineral
composition at a particular sample point in the drill hole.
Geologists can then survey the drilled ground analysis and make
decisions about the value of the overall mineral deposit.
Features of SOLLROC RC hammer and bit:
-Spare parts are made of quality raw material with carburized
treatment offer good wear resistance.The hammer achieve excellent
wear resistance and high penetration rate
-Various selection for bit head shape,button shape and button
configuration.It can completely satisfy the customization
requirement and have adaptability to varies of conditions.
-Rc bit is interchangeable with well-known brand shank.The
interchangeable shank design helps customers to optimized
inventory.

Advantages of Reverse Circulation Hammer:
1) Non-Blocking:Our RC hammers are proved to ensure extremely low
rate of blocking during it works.
2) High Efficiency:The well drilling equipment carries with larger
power of impact frequency and torque, thus ensuring faster
penetration. Compared with others, the efficiency can be improved
10%.
